The Icegraves is the traditional burial site for the leaders of the Varki people in the Linnorm Kingdom of Icemark. After having their brains and entrails removed (which are offered to the sky on a platform), the Varki bury the bodies in a grave melted out of the ice. Anyone who visits the burial site can see countless bodies amidst their burial goods perfectly preserved in the ice.1
