Koros

Koros is a Warsmith of the Iron Warriors Traitor Legion, and as such a master of attacking and defending every manner of citadel.

History
Warsmith Koros is a veteran of the Iron Cage, and one of the Daemon Primarch Perturabo's lieutenants, having proved himself worthy of command of one of the Iron Bastions on Medrangard, the planet-scale fortress Daemon World which is home to his Legion.

Koros has been dispatched to the Jericho Reach in order to oversee the fortification of numerous worlds about the Hadex Anomaly, and to lend his assistance in the planning of a grand counter strike against the forces of the Imperium. What price the various factions opposing the Imperium have agreed to pay in return for the Iron Warriors' aid is not known, but it must certainly be high.

Warsmith Koros is known to be in league with the corrupted Mechanicus of the heretical Forge World of Samech, who have equipped him and his forces with numerous items of heretek, some of which was undoubtedly constructed according to his own specification.

It is now suspected by several within the Chamber of Vigilance that Warsmith Koros and the Dark Mechanicus of Samech have entered into an unholy alliance, the only result of which can be the creation of a new generation of previously unseen and abominably powerful weaponry.

Armed with the twisted fruits of such a dark union, the servants of the Ruinous Powers might finally be able to break the deadlock that has befallen the Acheros Salient, and begin to push the lapdogs of the Corpse God Emperor back to the Well of Night, finally expelling them from the Jericho Reach.
