{{SpaceMarinePortalSpaceMarinesPortal}}'''{{PAGENAME}}Ansellus''' is the current [[Chapter Master]] of the [[Sons of Guilliman]]. Sometime after the [[Great Rift]]'s creation, the [[Industrial World]] [[Drevaris]] was invaded by the [[Tau Empire]] and {{PAGENAME}} Ansellus and the [[Silver Skulls]] Chapter Master [[Argentius]], led their Chapters' forces to aid the world. In the ensuing battle between the two forces though, both sides were devastated and as it neared its end, {{PAGENAME}}Ansellus' strike force consisted of only two other Marines. Argentius' strike force was also shattered, but luckily for the Space Marines, the Tau's [[Tau Commander|Commanders]] took stock of the losses they had suffered and ordered a retreat. It is only a respite however, for the remnants of {{PAGENAME}} Ansellus and Argentius' forces, as the Tau Commanders plan on launching another attack, once their remaining [[Fire Warrior]]s have regrouped together.{{Fn|1}}
