Daenistrasz is a frost wyrm located at the bottom of the Great Sea. He was one of the red dragons that destroyed the Kul Tiran Third Fleet during the Second War, while the dragons were controlled by the Horde.

Objective of

 * Water-Breathing Dragon

Trivia

 * He is portrayed as a frost wyrm instead of an emberwyrm very likely because he was not raised by the Scourge. Alternatively, having a smoldering model in the water would be odd.
 * Given the names, Daenistrasz may be a reference to from  /.

Speculation
The Cursed Eye of Paleth may be the reason Daenistrasz is undead, as it also cursed sailors of the part of the Third Fleet found in the Wetlands to become undead.
