Corio Vexa

Corio Vexa is a Line Warden of the Adamant Wardens chapter, seconded to the Deathwatch relatively recently under a requirement based on his Xenos murdering expertise.

Initiation
Corio was born on the chapter homeworld of Brigg to a family seeking noble power from the Great Knights of Adamantine, so they had sent their strongest son to go and try. He died. Then they proceeded to send a brother to this son up to their tower once more, a gruff and stoic child who was beaten for his quite common rebuttals and insolence to other children in their staunch warrior culture. He often never threw punches in return, but when he did those children were often worse for wear. His strength was never known and nor did he look the part or speak much. He was sent in the wake of his elder brother at 11, soon training as an aspirant and training with them for a year before starting his surgeries successfully. His records came in at above-average level, and were a sign of a talented warrior.

Soon came the rite of decimation near the twilight of his surgeries after a handful of engagements. All of them were lined up, and the War Priest(Chaplain) selected one tenth of their initiate pool and ordered everyone to kill them, Corio was on this list and was not about to die lone. He fought off every initiate, preferring to incapacitate but he did kill a few after all of his selected brethren died. He was commended for his strength and given an honor as his training progressed.

Astartes Career
Corio went on to become a decently useful Warden in the tactical field, getting several notable accolades and facing a number of xenos threats overall. Soon this expertise came into question and his Siegesmith ordered him be seconded to the deathwatch, being sent off with a salute and parting words to a Watch-Fortress.
