The Dark Aster was a three mile wide Kree Warship that served as a flagship under Ronan the Accuser's command and the base from which to launch his personal vendetta against the Xandarians. Though the vessel had no weapons of its own, it served as a carrier for the Necrocraft, housing hundreds within its rotating wings.
The Dark Aster served as the flagship of Ronan the Accuser, a renegade Kree terrorist that refused to honor the treaty between the Kree and Xandar Empires. Embarking on a campaign of his twisted version of "judgment", Ronan traveled the galaxy butchering many Nova citizens with the help of his soldiers and ships. Among its targets was the Kyln, the high-security prison of the Nova Corps.
Eventually Ronan, in possession of an Infinity Stone, attacked Xandar in order to destroy the planet. In a fierce battle involving the Nova Corps and Ravagers, the ship was eventually brought down to the planet's surface, where it was destroyed.
