Death's Demise

Death's Demise is the title associated with the achievement, being the first raid on a realm to slay Yogg-Saron on heroic difficulty without the assistance of any keepers. The title comes after the character's name, in the following format:
 * , Death's Demise

Inspiration
This title appears to refer to a famous couplet from the works of H. P. Lovecraft (which are also the basis for other features of the Warcraft universe, such as C'Thun and Yogg-Saron himself):


 * That is not dead which can eternal lie.
 * And with strange aeons even death may die.
