One of the dragons I killed during my stay in Northrend was Cyanigosa, a mighty female blue dragon, sent by Malygos himself to assault Dalaran. She was attempting to free prisoners in the Violet Hold, barely held back by the Kirin Tor. Several others and myself entered and fought the dragonkin, the nasty creatures they did free, and in the end, Cyanigosa herself.

A dragon in a confined space can be interesting, but she did not put up much of a fight.

Her death meant that Malygos’ assault on Dalaran was doomed – and eventually, the Aspect of the blue dragonflight would fare no better than Cyanigosa.
