Fall of Zeliath

The Fall of Zeliath was an Imperial defensive campaign conducted by the Dawn Guardians Space Marine Chapter upon the Imperial world of Zeliath, to recover vital ancient Imperial texts from the vile clutches of a Genestealer Cult, and the inevitable invasion of encroaching Tyranids.

Background
The Dawn Guardians send two Companies and a Demi-Company of Vanguard Space Marines to aid in the recovery of vital Imperial texts on Zeliath when Genestealer Cult uprisings threaten to shatter the world. The Vanguard of the Dawn Guardians carry out several successful archive recovery missions while the two Companies counter the insurgents. However, when Tyranid forces arrive on the world sooner than expected, the Dawn Guardians received a vicious mauling until they were able to pull out. Though Zeliath is lost, the Dawn Guardians escaped with the important texts and protected the knowledge on their pages. The survivors of the fall are marked with a campaign badge to honour their courage.
