From Warhammer 40k - Lexicanum
'''Roboute Guilliman''' was the [[Primarch]] of the [[Ultramarines]]. Roboute was lethally poisoned by the traitor Primarch [[Fulgrim]] and was interred in a stasis field at the moment of his death.
He now resides within the[[Temple of Correction]] on [[Macragge]]. Many pilgrims visit every year, claiming his wound on his throat is healing. This technally impossible within the stasis field, but enough people belive the story that they come back year after year to pay their respects to the Primarch
