Kaldor Draigo

Kaldor Draigo is the Supreme Grand Master of the Grey Knights and a warrior beyond reckoning. As a lowly Battle-Brother he banished the Daemon Prince M'kar the Reborn and he has risen steadily through the ranks to become the Grand Master of the most secretive Chapter of Space Marines. Yet ever since his battle with M'kar, Draigo has been cursed to a life within the Warp, doomed to walk within the Realm of Chaos. To remain pure when constantly assailed by Chaos shows such fortitude and personal strength that it is beyond measure. But while Draigo lives, he will prevail and one day, he will return.

Kaldor Draigo is famous for killing a daemon prince in his first combat action, banishing daemon primarch Mortarion back to the warp, somehow carving the name of the previous supreme grand master Janus into the heart of said daemon primarch - and somehow not contracting space daemon AIDS in the process, single handedly holding off a daemon horde for two days in real space, killing a daemon prince with a broken sword, Killing one of Khorne's strongest bloodthirsters with little to no weaponry, taking said bloodthirsters axe and reforging it into a sword for his own personal use USING HIS MIND (you know, despite it being an obvious weapon of a Daemon and automatically a corrupting influence), slaying 6 of Slaanesh's chosen daemonettes (when setting one's gaze upon them is enough to instantly force submission from any mortal, no matter how strong-willed), setting fire to Nurgle's garden (again, whilst somehow miraculously avoiding space daemon AIDS), walking into the City of Tzeentch and single handedly smashing it to rubble, which, given that the City of Tzeentch comprises geometry which is literally impossible, MAKES NO FUCKING SENSE, and slaying countless daemons whilst being trapped in warpspace. He can also be summoned by chaos cultists unwittingly instead of a daemon, no sooner returning to the Warp than after slaying them all. Yeah, he's a fucking troll....

The Emperor himself, looking at his deeds, stood up... And quit his fucking job because clearly this Draigo asshole made him irrelevant.

tl;dr

BECAUSE GW WOULDN'T LET MATT WARD BRING BACK ROBOUTE GUILLIMAN

Clearly, the only explination for the sheer levels of retardation and gratuitous canon-rape is that "non of it is real." Right now, this verry moment, Draigo is in fact a shredded pile of torn flesh and shattered bone after having his ass handed to him by above Daemon prince and Bloodthister. This pile of broken ex-marine is also gushing ooze and phlem as he was infected with every blight and pox Nurgle has to offer. This shredded, oozing "thing" is also being raped and violated in the most unspeakable and vile ways by the Daemonetts of Slaanesh. The only reason he thinks "all is well" is because Tzeentch thought he'd have a bit fun with Draigo. He stuck Draigo into a matrix-esque dream world where everything goes his way and is just waiting for Draigo to climb as high as he can. This dream world will probably last untill Draigo has crushed the Chaos gods themselves and all their armies beneath his feet and caused the Emperor to rise from the throne and such him off! Then, at the "funniest" possible moment, Tzeentch will rip it all away from him, Draigo will wake up and see what has realy become of him and weep tears of utter loss and despair! "Just as Planned!"
