Death is close...
C'Thun is one of the Old Gods: ancient and powerful creatures who had once ruled Azeroth long ago, but were defeated and imprisoned by the titans. C'thun currently resides imprisoned within the city of Ahn'Qiraj in Silithus, where it sent the qiraji to conquer the world in the War of the Shifting Sands, though the qiraji were defeated by the combined forces of the night elves and Dragon Aspects. Thousands of years later, following C'Thun's awakening, it prepared to imprison any dragons who dared enter its lair, but while its gaze was fixed upon them, a group of mortals managed to breach its chamber and kill it against all odds.

More powerful than G'huun who threatens to rupture Azeroth like a giant boil), Multiverse level via environmental destruction (Responsible for the corruption of the timeways and could potentially have corrupted the main timeway, which would result in doom and destruction throughout countless universes.
