Sardior

Sardior is a demigod honored by the gem dragons. Little of his history is known, except that he chose to aid the Estorians in their attempts to create a race of psionic dragons to battle the illithids. Since their release into Syra, Sardior has secluded himself in a flying castle that perpetually stays in the night, served by six gem dragon thanes. Though many gem dragons honor him for the part he played in their creation, he neither asks for nor receives their worship.
