'''Saint Tylus''' is a [[Shrine World]] of the [[Imperium]].{{Fn|1}}

==History==
In '''999.[[M41]]''', [[Ortan Cassius|Cassius]] led a force of [[Tyrannic War Veterans]] to the planet to reinforce the [[Ultramarines]] [[3rd Company (Ultramarines)|Third Company]] during an invasion by the [[Tyranid]]s of [[Hive Fleet]] [[Leviathan]].{{Fn|1}}

Above Saint Tylus, Cassius located a large form of [[Bio-ship]], the first time one of its type that had been discovered by the [[Imperium]]. As it was producing smaller [[Tyranid]] organisms at an alarming rate, Cassius attacked the ship with a contingent of Tyrannic War Veterans alongside a [[Space Marine Company|Company]] of [[Deathwatch]] Marines from [[Fort Excalibris]], managing to destroy it with [[Cyclonic Torpedo]] charges from within despite heavy casualties.{{Fn|2}}

Thanks to the tactics used by Cassius, the [[Chapter]] achieved the fastest known victory against a Hive Fleet assault.{{Fn|1}}
