Ivanoch is a Changeling Thief. He was one of the three Original Party members who fought and killed Tharizdun.
Ivanoch began adventuring after he, Coderous, and a Wilden escaped from an arcane magic testing prison. He fought in the Mind Flayer War, killing the lead Mindflayer. Sometime later, while he and Coderous were keeping watch on a reportedly haunted graveyard, Orcus appeared and attempted to kill both Ivanoch and Coderous. Both Ivanoch and Coderous prevailed however, and soon were appointed as personal assistants to the Gods, along with Gregory. After a devistating earthquake caused by the death of Allabar, Ivanoch, Coderous, and Gregory went through the planes, killing the evil gods who posed a threat to the world.
