Osmium was a chemical element with symbol Os and atomic number 76 that was mined on Sera. It was a hard, brittle, bluish-white transition metal that was utilized in applications where extreme durability and hardness were needed.


The Coalition of Ordered Governments mined osmium for use in the manufacture of various tools and devices. COG Armor was made using osmium and polyethylene fibers, and the bayonets of Mark 1 Lancer Assault Rifles were coated in osmium. One of the COG's sources of the metal was Osmium Mine Bravo in Tyrus, which was run by Nethercutt Mining and provided countless tons of ore before running dry and being shut down prior to Emergence Day.

Mining MethodsEdit

Osmium was extracted deep below Sera's surface using shaft mining methods. Massive elevator platforms called ore transporters were used to carry vast quantities of osmium ore from the depths of a mine to the surface, where it would be processed.


Osmium is in fact a real world mineral element. It is a transitional metal and is the densest stable element currently known. Osmium also has a blue-gray tint in line with the COG party's colors.
