The 29th Zetic Tygers have proven their iron resolve on numerous occasions, but never more so than on the space station of Valiant Mountain above Phellur III. After the Death Korps of Krieg interrupted a strange ritual aboard Valiant Mountain, a Warp rift opened at the centre of the superstructure, emptying thousands of Tzeentch 's minions into the star system. The Death Korps had proven too few to cope with the onslaught, and the 29th Zetic Tygers were despatched to make a sequence of strikes around the space station. By the time the Scions arrived, the Astra Militarum force had been all but destroyed.
