Immaterium - Realm of the Dead: Many cultures of the Milky Way Galaxy, both Human and xenos, believe that the Immaterium is the final resting place for the souls or spirits of the dead. Certainly there is some truth to this notion. The Aeldari believe that upon their deaths, their souls travel into the Warp where they are immediately devoured by their species' ancient enemy, the Chaos God Slaanesh.Because the Aeldari's hedonistic and intensely psychic nature was responsible for bringing Slaanesh into existence within the Empyrean following the Fall of the Aeldari sometime between the 29th and 30th Millennia, it can be said that Aeldari souls have a form of "psychic gradient" in which they are immediately consumed by the hunger of Slaanesh upon the death of their physical bodies if protective measures are not taken.For the Aeldari of the Asuryani craftworlds, this protection takes the form of the Spirit Stone worn by every one of their number which immediately absorbs their soul's psychic energy upon death so that it can later be deposited for safekeeping within their Craftworld's Infinity Circuit. There it will exist for all eternity as part of a gestalt collective mind of the dead.The Drukhari take a predictably more savage course. They are partially protected by their existence within the Labyrinthine Dimension of the Webway from consumption by Slaanesh, but "She Who Thirsts" will eventually consume even a Drukhari soul unless he draws psychic energy to protect himself from the psychic agony of others.It is for this reason that the Drukhari are such malevolent creatures, seeking out an endless supply of slaves whose torture they not only enjoy but which actually keeps their twisted souls intact.Amongst the mortal servants of the Chaos Gods, there is no doubt: when a mortal dies in realspace, their soul is immediately swept into the Warp at the moment their physical body dies, where it will be devoured by the Daemons and other Warp entities or made into their pitiable plaything for all eternity.The only salvation from this grim fate is to give oneself over body and soul to the worship and service of the Ruinous Powers either collectively as Chaos Undivided or individually as the Dark Gods may grant their more successful and powerful followers a favoured place within the Realm of Chaos upon their deaths.The most successful devotees of Chaos can even look forward to an existence as a Daemon Prince, a position of guaranteed immortality and control over one's own small demesne or Daemon World within the Realm of Chaos or a Warp rift like the Eye of Terror.The devotees of many variants of the Imperium of Man's Imperial Cult also believe that when a person dies, their soul is transported to the Warp.But a devout worshipper of the God-Emperor of Mankind holds that the Emperor protects His faithful within the Warp from all entities that might seek to harm them and gathers the souls of the faithful to Himself.Only someone who has not been faithful to the Emperor and carried out His will or obeyed His commandments is at risk of being devoured by Daemons of the Warp or otherwise punished for all eternity within the Empyrean.In this way, the devotees of the Imperial Cult see the Warp as an analogue of the old Judeo-Christian concept of Heaven and Hell -- the Warp is Hell for those who have been unfaithful to the God-Emperor, but can become a form of Heaven for those who have been true to His will.Whether there is any truth to this belief is unknown, but the psychic nature of the Empyrean means that the collective and strongly-held beliefs of mortals in realspace tend to take on a reality of their own within the Warp. And there are a great many Human beings in the galaxy, and a great many of them are fervent, even fanatical believers in the Imperial Creed.What is known with certainty is that those men and women of the Imperium who have displayed unshakeable faith in their concept of the God-Emperor like Euphrati Keeler and various other Living Saints have sometimes been able to enact feats that can only be considered miraculous by any fair use of the term.These feats have been particularly potent when deployed as weapons against the servants of Chaos, Daemonic and mortal alike. It may be possible that as the ancient credo tells us, the Emperor protects...
