Dark titan

Dark titan or Dark Titan may refer to:


 * One of the many titles of Sargeras, the lord of the Burning Legion.
 * A term used to refer to a corrupted titan world-soul, which has also been described as a "warped titan". See corruption of world-souls.

Speculation
The non-canonical World of Warcraft RPG source book Magic & Mayhem suggests that there are multiple dark titans, including Sargeras, trying to influence the world of Azeroth. These other titans may be ones that Sargeras corrupted and brought over to his will or perhaps they are just other rogue titans who have similar plans as Sargeras.
