Hatched on the floating island Aerie, Dania's people (the Bird-People) were originally from Sky-Island. At 14, Dania had spent most of her life watching Namor on video feeds, since she thought he was responsible for the death of her father (presumably the original Red Raven).
Namor's company, Oracle, Inc., sought to study the sunken Sky-Island and market the technology. However, the workers were attacked by Diablo, who sought to harness the island's technology for himself. Dania flew there to defend her people when Diablo alchemically resurrected the the Bird People (who were in a state of suspended animation), leaving Namor and Dania to fight them off. The reanimated version of Dania's father attacked her, and she was very distraught, but Namor defeated him. Diablo departed, exploding Sky-Island as he left. Dania chided Namor for his interference with Sky-Island, though she did win a grudging respect for the hero. Diana's father later organized his people into building a new Sky-Island.
During Civil War, Tony Stark listed Dania as a foreign national, who was still active in the United States.
Dania was one of the 16 super powered teens teleported to Murderworld by Arcade. After seeing Arcade kill Mettle, Dania in a panic tried to escape by flying up but hit a force field and came crashing down to her death.
