Saragosa is a great blue dragon who circles high above the Nexus. She serves both as guardian and consort to Malygos. If any serious threats arise, she alerts her master of the danger. Saragosa meets her death in  Saragosa's End.
When Saragosa first is summoned and lands on the platform, she is in her dragon form and a level 73 elite. When the fight actually begins, she turns into her human form and is a normal level 73.
