Queen Diamond was an IceWing animus and the queen of the IceWing tribe during the events of the book Darkstalker (Legends). She was the cause of most of the IceWing and NightWing rivalry due to her decided rage towards Prince Arctic and Foeslayer's scandalous romance. She was also one of the very few IceWings who used their animus powers more than once, mostly for vengeance. Diamond hated Foeslayer so much that, once Foeslayer was captured, she decided to make the NightWing immortal and lock her up so she could be killed over and over by future IceWings, in an event known as the Diamond Trial later on by her royal descendants and all IceWings recorded on the rankings.
