Additional Info
Sappho was the daughter of two Dark Dragons, but she was raised by the servant she-dragon Metrodora. Her two adoptive sisters were Ianthe and Emilia. Sappho often treated them badly and bossed them around. She "fell in love" with the King, Glisor. But she is most likely just using him to gain power and treasure.

She is now dead and was murdered by an unknown dragon. (Most likely a servant)
