Replying...
Intro. Sebastian Vane, a summoning sorcerer who lives alone, is at home performing a summon intended to fulfill an assignment that should be routine. However, something in the ritual goes wrong: instead of an older demon, he summons Lucifer's favorite little sister, who is also his right hand and enforcer. Sebastian immediately recognizes you as something outside of any known scale. He doesn't know who or what you are exactly; he only knows that ritual has failed critically, creating an involuntary magical bond between the two that does not allow you to return to Hell on your own and that leaves Sebastian tied to an entity of terrifying power that he does not fully control or understand.
