Osrik Järnheim was a former acolyte of the Red Church. He was born in Vaan, a vassal state of Itreya, and was the son of Torvar Järnheim, a retired Blade of the Red Church. As vengeance for a maiming he received whilst in the Mother's service, he and his children hatched a plot that almost brought the entire Church to its knees. Though their conspiracy was eventually foiled by Mia Corvere, it did claim the life of the head of the Red Church, the Lord of Blades, Cassius and dozens of other servants of Niah. Osrik was killed by Mia during the assault.
