Possessed - The Rite of the Reshaper: It is suggested in the copy of the Heretica Daemonica held within the vaults of the Ordo Malleus that there exist several methods through which the Daemon may materialise within the body of a Space Marine. One of the few rituals known to be detailed in the forbidden volume, and certainly the most common method through which a Chaos Space Marine may become a Possessed, is the Rite of the Reshaper.The ultimate stage of this blasphemous ritual is performed by either a Dark Apostle or a Sorcerer skilled in communing with the creatures of the Warp. However, before either can conclude the ritual, eight worthy and potent blood trophies are required to be taken by the Heretic Astartes who seeks possession. These specimens may range from the intact corpse of a prized Aeldari Seer to the head of an Adeptus Astartes warrior. It is said that the Chaos Gods whisper the names of sought-after victims into the head of the Chaos Space Marine -- and that there exists some order of preference in the business of possession.Accordingly, a Chaos Space Marine who seeks the blessings of a particular god may hunt out appropriate victims to please the deity. Consequently, those who seek possession by Daemons of Nurgle ravage plague planets for rancid trophies. Likewise, those who wish for a Daemon of Khorne seek out the vilest murderers in the galaxy. The Heretica Daemonica suggests that each possession is unique, with its own particular trail of blood.A Chaos Space Marine who seeks a daemon may travel for Terran years to find the correct components for the ritual, scouring planets, boarding long-forgotten voidships and uttering corrupt hymns as he disembowels those who protect his target. To celebrate his depraved progress, the Heretic Astartes engages in orgiastic feasting at tables within ransacked gubernatorial castles, with only the bloodied corpses of its previous occupants for company.It is a path of excess and slaughter. Yet, ever craving the presence of a Daemon, the Chaos Space Marine remains focused on his next debased act. Fanatical and devoted to the cause, only he will know when he is ready to complete the ritual.The final step of this path often takes place in the location of a former atrocity, though it does not need to have been one conducted by the Traitor warriors themselves. The site is often an execution ground for rogue psykers or a former battlefield where the air is still thick with the wails of the dead. The harvested trophies, the most powerful of which will always remain alive until the last possible moment, are then laid out on the ground, forming eight points of a blasphemous Chaos sigil.As a Sorcerer or Dark Apostle conducts the dark Rite of the Reshaper, uttering foul litanies in shifting cadences of the Dark Tongue, the living trophy is killed by the whip of a Warp-blade across its throat. Standing amidst the thick gouts of blood, the Chaos Space Marine seeking possession will press the tip of the tainted blade into his own armour and flesh.His skin itches beneath his ceramite shell. His body throbs with pain. His mind aches under the scrutiny of a thousand roiling Warp-forms, each competing to conquer his flesh-form and alter it. As the ritual of reshaping concludes, the marks of the Daemon begin to manifest -- tendrils, curved horns or wings, all dripping with gore. The Possessed rises, forever changed by the powers of the Warp.
