Kolvax
Warsmith Kolvax was commander of a Grand Company of Iron Warriors based upon the millennia-old fortress world of Forgefane. His personal citadel was called Ironblood Citadel and was said to have rivaled Perturabo's own fortress.[1]
During the invasion of Forgefane by Hive Fleet Leviathan, Warsmith Kolvax arrogantly declared that he would single-handedly defeat a Trygon they had named Tremorbeast. He was eaten whole by Tremorbeast shortly before it breached the defences of Ironblood Citadel and the fall of Forgefane.[1]
