Nightbane is a summonable raid boss in Karazhan. He is a fiery skeletal dragon, transformed by Medivh from Arcanagos and formerly of the blue dragonflight. While not the ruler of Karazhan, a position apparently held by Prince Malchezaar, many consider Nightbane to be the true final boss of the tower, due to his superior difficulty in the early days of the dungeon's release. A raid member must have completed the File:Neutral 15.png [70] Medivh's Journal questline to summon the boss. This means Heroic Shattered Halls and Sethekk Halls must be partially completed in order to obtain the [Blackened Urn], which is used to summon Nightbane.
