The Raynor Glacier was one of the great glaciers in the north of Terisiare, during the Ice Age on Dominaria. The glacier grew over the northeastern kingdom of Storgard, and destroyed its castle. Later, Soldev would be founded on its ruins.
A cavern inside the glacier was known as the Labyrinth of Raynor. It was here that Tevash Szat’s Phyrexian priest amassed black mana and where Jaeuhl Carthalion found the Amulet of Quoz at the end of the Ice Age.
