Alysrazor

The beautiful green dragon, Alysra, was once a loyal servant of the Green Dragonflight and their master, Ysera. Unfortunately, when Ragnaros returned to purge the world in flame, Alysra betrayed her allies and freed the mad Archdruid, Fandral Staghelm. As a reward, Ragnaros purified her in flames and was transformed into a dreaded Fire Hawk.

When Malfurion's forces assaulted the Firelands, home of Ragnaros himself, they found Alysrazor flying over the battlefield, watching her master's armies fight the invaders.

She made her final appearance as a boss in the Firelands raid instance, where in a final epic battle, Alysrazor was slain, thus allowing the heroes to get closer to their goal in Ragnaros' demise.
