Sheol

Selkis Stapleton was an ordinary rich girl in the country of Zephia. Her sole duty in life was to seduce and marry a wealthy lord. Bored with her stuffy life and overprotective parents, she began meeting with a mysterious stranger named Tefen and his friend, Penn, in order to learn the forbidden secrets of Magic. Thus, the Green Dragon Guild was born. Magic, and its patron goddess, Sheol, seemed rather harmless and intriguing at first, but soon the three friends would be sucked down into a vortex of madness, murder, and divine wrath.
