'''Crask''' is a [[Castellan (Imperial Guard Hierarchy)|Castellan]] of the [[Cadia|Cadian]] XVIIIth.^XVIII{{Fn|1 }} who was dispatched as part of an [[Imperium|Imperial]] fleet to fight in the [[Damocles Crusade]].

When his fleet emerged from the [[Warp]] they immediately besieged the [[Tau]] [[Sept]] of [[Kel'shan]] but hadn't realised that one hundred and fifty years had passed and the Damocles Crusade had already come to an end. Shortly after [[Hive Fleet]] [[Gorgon (Hive Fleet)|Gorgon]] descended upon Kel'shan and, faced with a common enemy, Crask and [[Kor'o]] [[Valroth]] agreed to a truce. Together their fleets turned on the hive fleet destroying nearly all of it's its [[Bio-ship]]s. Gorgon, unique for its ability to rapidly evolve its bioforms, was unable to adapt quickly enough to the disparate nature of the [[Tau]] and [[Imperial Guard]] forces combined and, at the [[Battle of [[Worldspine Ridge]], the forces of Gorgon were finally defeated. Valroth's truce with the Imperium also ended shortly after.^{{Fn|1}}
