From WoWWiki

The Dawnchaser is one of the three blood elf destroyers in the waters north of the Sun's Reach Harbor, Isle of Quel'Danas. She is the northeasternmost ship of the fleet.

This ship is one of three containing Dawnblade blood elves, as reinforcements for Kael's forces on the Isle of Quel'Danas.

After having set the sails ablaze, this ship is no longer able to continue to its destination.
