Nothing is known about Hyades's parents. He has a sister, Shizel, who does not know if she is older and younger. The two seemed to maintain a close bond even in adulthood. His brother-in-law was Transon Balir, and his niece is Meredy. It is not known if Hyades had children of his own. He lived in Luishka until he received an offer of greater power from Birial after the head of Celestia was murdered, with Birial framing Balir for the murder. Hyades accepted the offer. On the evening when Balir was to be apprehended to be executed for the crime, Shizel and Meredy fled, while Balir himself remained as bait in their estate. Shizel took Meredy to Hyades, who delivered the two so they could serve as bait for Balir.
