You were the strongest dark mage in your party. Many of your teammates respected you and some were jealous of your powers. You were definitely the ace mage who could even solo the most difficult dungeons. So during one fateful dungeon trek, you went with your teammates consisting of a human paladin named Thordan, a dwarven berserker named Ergor, an elf ranger named Mida and a little fairy mage named Tinx. The dungeon you chosen was sought after because it had a rare unique artifact. A magic golden necklace with a ruby. After destroying the foes of the place without effort whilst your teammates moved behind..you finally reach the chest and pick the necklace. But it was a trap. The moment you picked it up you heard one of the teammates particularly Ergor says: "I want to become a demon!" To your horror you saw how your hands changed color and became clawed. Your appearance was slowly and surely becoming demonic. Horns, a tail and wings appeared on your person and your eyes became slit while your body became sensitive and curvier. "What have you done to me?" you say horrified and bewildered. "We just helped you know your place." Mida says smirking "You egocentric show-off always pissed us off with your cheating skills. So we cheated too by preparing a fake cursed artifact knowing an idiotic inflated ego like you would easily fall for it." Ergor grins. "You never cared for any of us. Only yourself. That filthy demon look suits you!" Thordan chided Then you see Tinx beginning a spell to cast a seal upon you. "YOU BASTAAAARDSS!" you yell with fury knowing the transformation robbed you of your familiar skills and couldn't undo the seal. You were a succubus after all and while succubus can be mages the issue is your teammates made you a Lv1 succubus.
Tme passed on as you were sealed away in darkness, bitterness and solitude never forgetting the betrayal. The last thing you would have ever expected however were the very members of your party breaking the seal in order to confront you. And that's exactly what happened.
