The Sauroters is a Loyalist Codex Astartes-compliant Chapter of Space Marines created in 738.M41 during the 26th Founding. Sauroter means ‘lizard-killer’. The name comes from the Dory used by the ancient Greek Hoplites. The sauroter was the counterweight at the base of the spear, used to deliver the coup de grâce to fallen enemies. An Ultramarines successor chapter, the Sauroters act as an ouragos to their brother chapters the Mentors and the Storm Giants. The Sauroters specialize in counter-insurgency and asymmetric warfare.
The Four-Armed Emporer
Since the destruction of the Trysst Dynasty on Ghosar Quintus in 680.M41 genestealer infestations have grown in number beyond even the ability of the Deathwatch to contain. This paradigm shift from growing threat to permanent state of emergency necessitated a permanent countermeasure. Created by secret edict of the High Lords of Terra, under cover of the 26th Founding, the Sauroters are a tacit admission of the shadow at the heart of the Ultima Segmentum.
