Valhallan System

The Valhallan System is an Ultima ice well whose principal world Valhalla was a green colony until an iron comet knocked it off its orbit and froze the oceans. Survivors dug cities into the ice and learned to hate Orks in the War of Survival.

Ice Warrior regiments still treat cold as a home advantage. After the Rift the world sits in Imperium Nihilus. Tanna tea is the local comfort; the corridors are not. This is a Guard home, not a Fenris copy.

The Valhallan System still matters as the freezer that keeps exporting Ice Warriors. Unofficial summaries keep the Ultima parent and do not relocate the pin to Segmentum Solar.
