The Shrine World of Torfal becomes another important stepping stone for Castor - it was his first tangle with the Sisters of Battle. It was the daemonhost Karnak Zul that led Castor here – he claimed the head of the Dusk Hag was kept locked away at a remote temple. That proved to be the case. It also proved to be the case that the temple was heavily guarded by Sisters of Battle. They put up quite the fight, but in the end Castor did (of course) prevail. 

Following the raid Castor called his banners so to speak. It was time that Torfal was brought into the light. Several generations ago the Inquisition purged the world of 90% of its population. It has since recovered somewhat and dedicated its existence to placating the God-Emperor. What better place to test the mettle of his warriors? What better place to build a pyre and sacrifice the worthless followers of a dead god? Castor invades - and ravages the entire capital province of Orlist, killing or enslaving every man, woman, and child.
