Lightbreaker

The Lightbreaker  is a Legion command ship situated in Felsoul Hold. It belonged to the demon commander Azoran who planned to use it to destroy Dalaran. The portal to the ship was locked by a key halved into two shards which Azoran had given to his two generals, the ered'ruin Vorgos and the jailer Kozak the Afflictor. While the Illidari Lyana Darksorrow held the demonic reinforcements at bay, the order leader who accompanied her crossed the portal and slew Azoran.
