Gryphadin

Gryphadin is Brann Bronzebeard's trusty gryphon mount. He was purchased so that Brann could travel the South Seas. He is named after Muradin, Brann's fallen brother. While visiting Plunder Isle, Gryphadin was turned to stone by a basilisk. Brann was able to restore him using a packet of magic dust.

Brann's gryphon seen in the Ulduar trailer may be Gryphadin.
