Grimnak and his t-rex mount were summoned from Grut.
Grut is a primitive and savage planet.[1] It is known in Heroscape's canon for its unique blue-skinned orcs, and the dinosaurs and Ice Age era megafauna upon which they ride. It was the homeland of some of Utgar's prominent heroes such as Grimnak, and hordes of Grut Orcs formed the body of Utgar's initial invasion forces summoned to Valhalla.[2]

At one point, Grimnak was exiled from the planet, although it is unclear if this just means he was summoned to Valhalla by Utgar. At some point, Nerak returned from unknown circumstances.
