kaldor draigo
Kaldor Draigo is the current Supreme Grand Master of the Grey Knights Space Marine Chapter.
Lost in the Realm of Chaos within the Warp for at least the last standard century, he is sometimes able to return to realspace to fight alongside his battle-brothers in the Grey Knights during particularly dangerous Daemonic incursions.
But one day, when his Chapter and the defenders of the Imperium of Man know their darkest hour, he will return to the mortal realm permanently to lead them to victory.
