'''Samus (Daemon Prince of the Ruinstorm), The One Who Walks Behind Us'''{{Fn|6}} is the name of a [[daemon]] that was initially manifested on [[Sixty-Three-Nineteen]] near the end of the [[Great Crusade]].{{Fn|1c}}{{Fn|1d}} The creature went on to plague the Imperium throughout the [[Horus Heresy]].

{{spoiler|source=The End and the Death (Novel)}}

Like all particularly powerful Daemons, Samus is an echo of a particularly powerful act or emotion that has taken place within the [[Materium]]. The time of this act within the Materium is not particularly relevant to the Daemons manifestations, as there is no time within the Warp. Thus, Daemons may be spawned from acts that take place well after they first appear. In Samus' case his birth is the result of the murder of [[Garviel Loken]] at the hands of [[Erebus]].{{Fn|12}}

The entire "Samus incident" was hushed up by order of the [[Warmaster]] [[Horus]], to hide both the knowledge that an [[Astartes]] had turned on his fellows, and that it was possible for malignant warp-entities to corrupt them.{{Fn|1d}}

{{spoiler|source=Know No Fear (Novel)}}

Samus would appear again during the [[Battle of Calth]] as part of the demonic army summoned by [[Erebus]]. This time he possessed the body of [[Word Bearers]] [[Space Marine Captain|Captain]] [[Morpal Cxir]], who deliberately provoked [[Ultramarines]] Captain [[Teus Sullus]] into killing him, in order to "summon" Samus into realspace.{{Fn|2a}} Samus ran amok inside the Ultramarines' stronghold, but was finally banished after being stabbed by Captain [[Remus Ventanus]], using Cxir's own [[athame]] knife.{{Fn|2b}}{{Fn|2c}}
