- "In Honor of Those Who Served. To all those we lost during the Pendulum Wars, may they rest in peace, and know always that their brave sacrifices were not in vain. Never shall they be forgotten."
- —Landown Memorial
The Pendulum Wars was a global war that lasted from 79 B.E. to 0 B.E. It involved the two superpowers of Sera, the Coalition of Ordered Governments and the Union of Independent Republics, for control of the planet's natural resource of Imulsion. Millions of human lives were lost in the conflict and the environment was significantly damaged by the devastating weapons. The war was a deadlock for it's majority until the COG broke the stalemate by going around the land warfare with the UIR and staging a daring raid on Aspho Fields. The COG stole the Hammer of Dawn technology plans during the Battle of Aspho Fields and gained the advantage in the war. The Pendulum Wars ended shortly before the attack on the surface of Sera by the Locust Horde on Emergence Day with only six weeks of peace between the two wars.

Decades before the Pendulum Wars, Sera was plunged into the millennia-long conflict known as the Age of Armageddon, nearly destroying both the human race and Sera. Realizing their protentional extinction, humanity rejected war and embraced a new era of peace, known as the Era of Silence, leading to the development of a new cultural and intellectual renaissance with the advancement of the arts, scientific endeavors and cultural pursuits being key social priorities. Human culture also became increasingly demilitarized as the people's energies were channeled more toward improving the quality of life and the resolution of the past military conflicts, leaving little need for large armed forces to be maintained in spite of occasional skirmishes.
However, concerns over crime and the protection of the civil liberties were prevalent in this period, as both state and society debated the balance between freedom and security. In addition, there was a growing energy problem on Sera as existing hydrocarbon and nuclear fuel sources began to be depleted, pressuring humanity to find and exploit new sources of energy to maintain themselves and their lifestyle in the long-term. During an oil-exploration drill, humans discovered Imulsion, a phosphorescent and low-viscosity fluid from within the underground of Sera, known as the Hollow. Unusable as an energy source, it was nothing more than a scientific curiosity until Dr. Helen Cooper created the Lightmass Process, which enabled the refinement of Imulsion into a source of cheap energy.
Seemingly limitless, the discovery of Imulsion as a fuel source marked the beginning of the Golden Age. The full implementation of this process by most of the existing nations cemented Imulsion’s place as a new and fairly abundant energy source and led to the near-complete elimination of the hydrocarbon and nuclear-based fuel sources. However, the extremely low price of Imulsion energy and the massive loss of revenue and jobs in the traditional energy-production industries caused the world economy to collapse. The few countries that discovered an abundance of Imulsion within their borders found themselves as Sera's economic, and therefore political, superpower.
The Rise of the COG
During the seventy-nine year war, the Coalition of Ordered Governments or the COG became a legitimate and political party. Founded long before the Pendulum Wars by a fanatical socialist named Alexiy Desipich, the party was based on an obscure world-government philosophy based on eight guiding principle values: Order, Diligence, Purity, Labor, Honor, Loyalty, Faith and Humility. The COG began sending their legions of Gear soldiers out, transforming the Pendulum Wars from a conflict over Imulsion into a fight over freedoms. The Coalition overthrew many nations and incorporated them as vassal governments, accepting the volunteers to fight the UIR armies.
Early Pendulum Wars (79 B.E. - 53 B.E.)
Construction of Azura
Within the first few decades of the Pendulum Wars, many feared that it would end in global annihilation. This concern was held by the highest members of the Coalition of Ordered Governments. In preparation for the possible destruction of the planet, the Coalition began construction on an elite bunker facility on the island of Azura. Key members of the Coalition: politicians, servicemen, scientists, artists, and celebrities would be relocated to Azura during the global catastrophe in order to protect the most valuable members of society in order to rebuild with the most keen minds. Due to this, the bunker was designed as a lavish resort. Among the greatest minds of the COG to be involved with the construction of Azura was famed geneticist, Dr. Niles Samson. However, he was called back to the mainland when a more pressing issue required his expertise.
Mid-Pendulum Wars (52 B.E. - 27 B.E.)
New Hope Research Facility
After decades of Imulsion mining, it was discovered that overexposure of Imulsion caused a fatal lung condition known as Rustlung. The condition was found primarily in Imulsion miners and residents of Imulsion townships. Fearing the political and economic ramifications and mining, refining, and selling a toxic fuel source - the Coalition's Department of Health, under the Monroe administration, opened the New Hope Research Facility to house the children of Imulsion miners infected with Rustlung in an attempt to study the disease and find a cure to continue Imulsion mining. Dr. Niles Samson was tasked as the facility's director. To the progression of Rustlung, Dr. Samson and the other scientists injected the children with doses of concentrated Imulsion on a daily basis. They discovered that Imulsion's effects lead to intense and immediate cell stress, later causing metastasis and death, but other cells underwent point mutations that was considered beneficial for genetic engineering. Through testing, it came to light that one of the children, Myrrah, exhibited a genetic immunity to Rustlung, and in fact benefitted from Imulsion exposure - such as decelerated aging and an increased immune system. Seeing that genetics were the key to finding a cure, Dr. Samson branched into transgenics.
Believing that indigenous creatures of the Hollow were immune to Imulsion, Dr. Samson hoped to replicate Myrrah's genetic immunity in the other children by splicing them with the DNA of the creatures from the Hollow. However, this mutated them into deformed, mindless, feral creatures that he referred to as "Sires". Patient zero of Rustlung, Ukkon, was the only child to retain his sanity after transforming, but was just as sadistic. Like Myrrah, Ukkon gained the ability to heal wounds instantly when exposed to Imulsion, making him physically immortal. As a safeguard, the scientists designed a Cytostatic Gas to block Ukkon's regenerative abilities and make him vulnerable. This then caused Dr. Samson to no longer pursue a cure for Rustlung, but the ability to evolve the human race into a stronger, healthier, immortal species - with the Sires having potential for military combat in helping end the Pendulum Wars.
However, the Sires were genetically unstable, distempered, and sterile - making them unsuitable for an independent species. The Sires also caused numerous violent attacks against the staff at New Hope. Many employees resigned and leaked details to the public regarding the work at New Hope, but Dr. Samson was able to quiet most of the rumors. Private Sid Redburn, a guard at New Hope, was the whistleblower and alerted Colonel Tolman to contact Chairman Monroe about Dr. Samson. The COG then issued a formal investigation into New Hope and discovered the rumors of child imprisonment, torture, and unethical experimentation were true. While Dr. Samson attempted to persuade Chairman Monroe that the Sires had military potential, Monroe ordered the facility shutdown and all involved to be indicted. However, a secret political group within the COG believed in Dr. Samson's work and its potential to end the Pendulum Wars by using genetically enhanced soldiers. Wanting him to continue his work, the party relocated Dr. Samson, his remaining loyal employees, and many of their subjects to a secret laboratory hidden in Mount Kadar. Several Sires were left behind in stasis, protected by semi-sentient security system designed by Dr. Samson and based off his personality. With Dr. Samson and the people of New Hope disappeared, the COG closed the New Hope facility and classified all documents relating to the research there.
The Ostri front was fought thirty years before the Siege of Anvil Gate, in 47 B.E., and saw the extended trench warfare. Lt. Victor Hoffman compared the fighting inside the walls of Anvil Gate to the Ostri front.
Mount Kadar Laboratory
Without the scrutiny of the COG or public eye, Dr. Samson was allowed to work with impunity. Attempting to overturn the genetic instability and sterility of the Sires, Dr. Samson attempted in-vitro fertilization of Sire DNA, but each resulted in deformed and dead offspring. Myrrah, now older and groomed into being one of the scientists, then used her embryonic stem-cells with Sire DNA, resulting in a successful female hybrid called the Matriarch. The Matriarch was able to reproduce and created the first generation of Drones, labeled the Locust Horde for their ability to cause a massive degree of death similar to insect locusts. It was discovered through Myrrah and the Matriarch that all members of the Locust Horde were connected telepathically to a Hivemind, in which Myrrah was able to control - fulfilling Dr. Samson's attempt to create a highly controllable army of perfect soldiers. The Matriarch was suspended in a tank of cryptochromic fluid and connected to a brain-scanning device to that the pyschomagnetic bond she and Myrrah shared could be amplified. Dr. Torres, one of the lab's best geneticists, developed a romantic relationship with Myrrah and conceived a human child together, a female named Reyna. It was revealed that Reyna had inherited many of her mother's genetic abilities, including her connection to the Locust Hivemind within her temporal lobe.
Dr. Torres feared the experiments his daughter would be subjected to and thus escaped the facility with her. Unable to recapture them both, Dr. Samson lied to Myrrah that Reyna was killed during the escape attempt in order to keep her contained in the facility. However, the scientists underestimated Myrrah's maternal feelings toward both her daughter and her Locust children. The Locust themselves longed for independence and felt imprisoned and tortured by the scientists. Resentful of the humans for the treatment of her and her children, Myrrah used the Matriarch to compel her Locust to rebel. The Locust escaped and used discarded tools and weapons to slaughter the scientists and guards. Dr. Samson, mortally wounded, downloaded his consciousness into a robot before commencing a lockdown of the facility - using the cryogenic gas to freeze the facility and keep from a containment breach. Myrrah and many of the Locust were able to escape, however, and went deeper into the caverns of Mount Kadar. Acting as their Queen, Myrrah led the Locust to develop and build their own civilization, known as Nexus.
Late Pendulum Wars (26 B.E. - 0 B.E.)
- "Like everything in the COG army, there's an acronym for street fighting: M.O.U.T. "Military Operations in Urban Terrain." We just know it means close, personal, and higher casualties. In the Pendulum Wars, some guys couldn't take it. Black outs, freaks outs, suicides. You didn't give 'em shit because it might be you someday. To win M.O.U.T. battles, you need numbers, the manuals advise three to one odds to beat an entrenched urban force. If we're lucky the odds might be three to one--against."
- —Cpl. Dominic Santiago on urban warfare.
One of the most notorious fronts of the war, the Eastern Front saw the Duke of Tollen's Regiment of Tyrus battling the Gorasni soldiers loyal to the UIR. Several Gears are captured and sent to the Ramascu labor camp and several perished in the camp. The events of the Eastern Front and Ramascu left a great distrust for the Gorasni people among the COG citizens and Pendulum War veterans.
- "Your priority is to stop the UIR advance within Kashkur. COG forces hold the central plains of the country and the extreme west, but the UIR is widening its corridors between the areas we still hold. The Anvegad Pass is blocked and must remain so if we are to stop the UIR closing the circle and inserting land forces from the east."
- —Col.James Choi, commander of 6th Brigade.
The COG defended the Imulsion rich nation of Kashkur from the UIR nation of Furlin. The COG was able to contain and hold the Indies off until the president of Vasgar resigned shortly before a vote of no confidence. This gave the UIR the opportunity to invade Vasgar and open a second front on Kashkur, allowing the UIR to attack the infamous fortress of Anvil Gate on the southern front. While an Indie army flanked on the western border from Furlin, their aim was the city of Shavad.
The COG response to the Indies sending “peacekeepers” to Vasgar was to cut all Imulsion supplies to area, hurting the Imulsion Company and putting millions of Vasgar citizens in the dark, effectively shutting the power stations and hospitals down. The operation would force the UIR to ship the supplies in from the neighboring friendly UIR nations while having to deal with a local population without a government and fuel. The only thing of military value left for the UIR in the Imulsion-starved nation would be the iron ore and vast factories in southern Vasgar if the UIR could keep the peace in the nation.
The Indie troops from Furlin invaded Kashkur from two fronts: On the western border by hitting the city of Shavad and at Anvil Gate on the Vasgari border in the south. On the Vasgari-Kashkur border, the Indie sabotage effectively cutted Anvil Gate's only land route off by destroying the canyon, showing that the UIR had dozens of Special Forces in the country before the fall of the Vasgari government. An Indie soldier with an RPG in the nearby cannons was able to kill Captain Sander and several other Gears, leading Lieutenant Hoffman to request a Pesangi detachment. However, High Command was unable to deliver the fresh supplies or reinforcements since every Tern and the newly introduced King Ravens are occupied with the combat missions in Shavad.
The UIR laid siege to Anvil Gate where the COG with a handful of Pesangi commandos defended the Gate from the overwhelming forces. The siege lasted for three months and the fort was reduced to rubble from the continuous Mortar attacks. Hoffman's Pesangi troopers are able to kill several Indie spotters in the hills, but with a lack of food and growing unrest, Hoffman was forced to face the facts on the ground. He realized that Anvil Gate and the garrison could not last any longer, but fortunately for Hoffman, the Indie Major allowed the civilian population to evacuate the garrison if the COG surrendered. Hoffman took the only option that he had left and ordered the surrender of Anvil Gate to the Indies, but Hoffman's surrender was merely a ruse. He planned to entrap the Indies in the old quarter of the city and catch them unawares. The plan worked and over 200 Indie soldiers are killed, though the Gears suffered from many casualties as well. The victory at Anvil Gate allowed the COG to hold the southern pass and launched Major Hoffman's career.
Indie invasion of Irohma island
For ten years, the Gears and Indie soldiers located on the two guard posts never exchanged fire. A gunner named Evan while stationed at Anvil Gate would recount the anomaly.

Since 17 B.E., the UIR and COG fought for control over the nation of Sarfuth. While neutral Maranday stopped any outright invasion by the two superpowers, the UIR was amassing the forces in the Republic of Lauczi to attack Sarfuth. The COG forces decided to take an Indie strategy and used Maranday's neutrality to launch a daring raid into the Indie territory. The raid was successful and the COG forces are able to use their air force and take the advancing Indie army out at the Maigar Pass.
Around 3 years before E-Day, the Indie saboteurs are operating from neutral Maranday to attack Sarfuth's Imulsion pipelines while the members of the 26th Royal Tyran infantry defended the areas and killed at least one saboteur.
- Main article: Operation: Leveler
The climax of the war was at Aspho Fields with Operation Leveler. The COG forces discovered that the Indies at Aspho Point won the arms race for the orbital weapons. The COG could not allow the UIR to have an advantage in the war so they prepared for a daring raid by mobilizing the 26th Royal Tyran Infantry and Navy in an amphibious assault on the Ostri coast. The 26 RTI attacked the Ostri troops at Aspho Fields while the commando detachment under Maj. Hoffman raided Aspho Point. The Indie forces inflicted heavy losses on the COG, but the COG managed to accomplish their mission and evacuated from Ostri. The operation had the largest number of Embry Star recipients in Coalition history.
In the last year of the war, the Battle of Gatka Ridge was fought on the island of Knifespire in the Lesser Islands Chain over an Imulsion source located there. Lieutenant Colonel Gabriel Diaz led the COG forces in the battle, ultimately dropping a mountain on the Imulsion source to keep it out of the UIR's hands. Diaz refused orders from Deputy Chairman Richard Prescott to retake the Imulsion source no matter the cost and, disillusioned with the COG's bureaucracy, purposefully demoted himself to Sergeant and transferred to the motor pool to continue helping in the war effort without being forced into such a position again.
After the raid at Aspho Point and the Battle of Aspho Fields, the COG would battle the UIR for another two years by losing thirty-thousand soldiers. Adam Fenix used the stolen Hammer of Dawn technology to create the satellite-based weapons for the COG. For his efforts, Chairman Tomas Dalyell awarded him the Octus Medal. The COG forces are able to advance into both Furlin and Ostri. On the coastal city of Bonbourg, the COG occupied the city, but the UIR Third Fleet bombarded the city until the COG unleashed their newest weapon, the Hammer of Dawn. The Hammer destroyed the five Indie ships and forced the fleet to withdraw. While in Furlin, the Indie troops battled in Ghato City and around several cliffs. After the Hammer strikes on the Indie fleet, Premier Yori Deschenko entered into negotiations with the COG and the UIR surrendered. Despite this, some UIR units continued to fight, believing that the surrender was COG propaganda while the Gorasni would continue a guerrilla war.
Mutiny at OZP-11
Following the announcement of the peace negotiations, Premier Yori Deschenko sent Major Girek Toly to OZP-11, a UIR cosmodrome built in occupied Vasgar to oversee the dismantling of the functional Hammer of Dawn satellites built by the UIR. Shortly after Toly's arrival, the commander of the Gorasni troops stationed in Vasgar, Major Garron Paduk was tasked by the High Council of Gorasnaya with taking OZP-11 in order to launch the satellites and execute a retaliation strike in response for the defeat at Bonbourg. As the reports of violence between the UIR troops reached Toly, he reinforced the cosmodrome garrison with a brigade of hand-picked soldiers and soon after, Paduk's troops laid siege to the base. Toly ordered his men to infect the cosmodrome's computers with a semi-sentient malware in order to prevent the rebels from launching the satellites. After 3 days of brutal fighting, both sides suffered from heavy causalities and as the rebels are close to acquiring the Hammer of Dawn targeting beacons, the COG forces dropped a Lightmass Missile on the facility, killing or wounding nearly all belligerents and stopping the mutineers from achieving their goal, preventing the launch of the UIR Hammer of Dawn satellites and continuation of the Pendulum Wars.
The COG's armed forces revolved around it's Army branch until the Battle of Aspho Fields. Their Special Forces and Navy are given less attention, though Adam Fenix argued that the Navy and Air Corps must be expanded. The COG Navy contained the battleships in the early years of the Pendulum Wars and had a diverse range of ships including the destroyers, submarines and helicopter carriers.Two years before E-Day, the COG Navy attacked and leveled Berephus and Bonbourg while the LCTs landed on Aspho Fields. The UIR Navy along with the Gorasni Navy had submarines and missile frigates that are able to survive the Pendulum Wars and Locust War. During the Pendulum Wars, the UIR had the Tennad sailors use suicide submarines against the COG.
- "After decades of conflict, the Pendulum Wars will soon be over. The people of Sera will once again be united - sharing in this invaluable gift of Imulsion as once-optimistic discoverers had always envisioned. Both rich and poor nations alike, may I be the first to salute the world as we enter this golden age of prosperity, and peace."
- —Chairman Tomas Dalyell remarking on the results of the Pendulum Wars, with Sera becoming unified and entering a new golden age.
- "At 1000 hours this morning, the Union of Independent Republics signed a formal surrender to the Coalition of Ordered Governments and concluded a peace treaty. It is with profound relief that I tell you the Pendulum Wars are now at an end, and that the COG and UIR will embark on a program of reconciliation and rebuilding to heal the terrible scars-individual and national-that this long, terrible conflict has left upon Sera. We hope that the state of Gorasnaya will come to accept our offer of reconciliation and formally agree to the cease-fire in with other UIR states."
- —Chairman Tomas Dalyell's official announcement that the Pendulum Wars are over.
After the final battle of the war, the COG and UIR signed an armistice ending the war in the COG's favor. The COG replaced several Indie nation governments with pro-coalition governments including Pelles and Ostri Republic which are under the administration of Premier Yori Deschenko. Some Indie nations refused to surrender and launched an insurgency which was the infamous Republic of Gorasnaya. The Day of the Fallen holiday was created to celebrate the fallen Gear soldiers.
- "Should I tell Dalyell what's coming? No. I can still stop it happening. I can avoid more bloodshed. I'm the only one who can."
- —Adam Fenix
For six weeks, the COG ruled almost all of Sera before Emergence Day. Just as they started to rebuild the cities and towns that are destroyed and fix the international relations with the UIR nations who are still fighting against the COG, an unidentified enemy that would come to be known as the Locust Horde emerged from the underground warrens of Sera and launched a planet-wide invasion of the surface. The COG was unable to hold back the Horde, losing all of what they gained in the 79-year Pendulum Wars. However, the COG war machine was able to mobilize from the Pendulum Wars allowing them to quickly regroup and counter the Locust during E-Day, resulting in a new long war of extermination.
15 years after E-Day, the survivors of the Republic of Gorasnaya joined the COG for protection from the Locust before the Lambent Pandemic forced the COG to disband and caused the Gorasni to leave the coalition. However, the Gorasni remained allies with the remnants of the COG, saying that while they remembered their grudges, they also remembered kindness and those that are their allies, coming to the aid of the COG remnants during the Second Battle of Azura where Adam Fenix destroyed the Locust and the Lambent with an Imulsion-targeting weapon, bringing peace to Sera once again.
A lesser observed effect of the Pendulum Wars was significant damage inflicted upon Sera's environment. While Imulsion was cleaner than the traditional energy sources, it's large-scale exploitation by the massive war machines of Sera polluted the planet's soil, oceans and air. This caused the rampant cases of Rustlung in the humans during and after the Wars and would eventually contribute to the Lambent Epidemic as many are at least marginally exposed to Imulsion. The battles of the Pendulum Wars scared many regions of Sera. Both the COG and UIR committed serious human rights abuses in depriving the civilians of the natural resources. All of these factors began to change Sera's larger climate as HMT Magazine reported a noticeable increase in the catastrophic hurricane storms in the later years of the Pendulum Wars. While tragic, this environmental degradation would be pale in comparison to the subsequent Locust War which nearly rendered Sera lifeless.
- "And now we go and do it all over again. Another pointless battle. Another bereaved family. Another year of war. And the UIR does exactly the same. Someone has to break the cycle. Someone has to create weapons so powerful that if politicians want to wage war, they'll face the same death as the men and women send to fight it. A deterrent. A damn big deterrent. I can build a deterrent that'll bring governments to their sense. An orbital weapons system. That's my duty now."
- —Adam Fenix envisioning the Hammer of Dawn.
- "Some have said that war is hell. War is not hell... for in hell, innocence is spared."
- —Tai, after discovering the ethnic cleansing of his village.
- "And now you can see what we are fighting for. Imulsion."
"I thought we were fighting for democracy."
"No, I'm pretty sure it's Imulsion, Quinn. Cars don't run on freedom. Whatever that is."
- —Helena speaking with Pvt.Quinn about the COG's motivation for fighting the Pendulum Wars.
Behind the Scenes
The Pendulum Wars may be named after the Pendulum which was a weight suspended from a pivot so it could swing freely. It was most likely a representation of the war and it's stalemate until the Battle of Aspho Fields. It could also be suggested that it was a reference to the number of machine-related names in the Gears of War universe.
