Valiant Mountain
From Warhammer 40k - Lexicanum
Valiant Mountain is an Imperial Space Station in orbit of the planet Phellur III.[1]
History
At one point a Chaos ritual was enacted aboard Valiant Mountain. However, when the ritual was interrupted by Imperial Guardsmen of the Death Korps of Krieg, a warp rift opened at the heart of the station which allowed Daemons of Tzeentch to encroach on the Materium.[1]
The Death Korps were reinforced by the Tempestus Scions of the 29th Zetic Tygers regiment. They led a series of strikes against the attacking Daemons, breaking through to the Lord of Change commanding them. On defeating the Lord, the warp rift was sealed.[1]
