Forest of Knives

The Forest of Knives is an ancient place, located deep in the frozen wilds the Norscan Peninsula, at the edge of the Chaos Wastes. The Winds of Magic blowhard there, corrupting all they touch.

History
Long before the Coming of Chaos, the Elves colonized the area and built a city in the Forest of Knives. But when the Polar Gates failed, allowing the Daemons of Chaos into the world, the colony was abandoned as Norsca was too close to the Northern gate. Even after the Daemon-tide was beaten back, the Norscan peninsula would forever remain tainted by Chaos.

The Elven City remained undiscovered within the forest for centuries, with its temple and Waystone remaining intact. Thousands of years later, the ruins of the city was discovered by escaping Imperial and Kislevite captives, who were by the Norscans during their raids to become slaves and sacrifices. As they were without a ship to cross the Sea of Claws, they settled in the ruins and were relatively safe for a time. That is until Vigrun Skraeling and his warband returned to Norsca after the defeat of Chaos in the Great War. A champion of Slaanesh, Skraeling traveled to the Forest of Knives looking for refuge and found the Elven city. He desecrated the still intact temple and took the City as his, forcing the refugees to flee to the surrounding Forest.
