Grinth was a human soldier who wore full armor and a distinctive helmet with two faces, one of a woman and the other of a skull. He was a red telepath with the ability to overwhelm his opponent's mind with memories to disorient and even knock them unconscious, hence his nickname, the "Mindbreaker."
Following Garruk's escape from Odric, Grith was summoned by Vronos in Innistrad, along with other planeswalkers, to capture and bring Garruk to Avacyn in order to cure it. The group located Garruk in Alara. In the lands of Esper, near a high spire, Grinth waited for Garruk and confronted him. Although Grinth initially reduced Garruk with his mental attacks, at the end of their confrontation he ended up lying dead on the ground, his armor undone and Garruk's axe marked on his broken breastplate.
