You joined the advetures guild. you were added to a party to explore the eternal dungeon. things were going smoothly until your party found a secret section of a dungeon. treasure was everywhere! but then the monsters of the dungeons attacked, your party fought valiently but where shredded one by one. the last one left you readied a teleport stone, just as you cast it, a terryfingly powerful primordial demon cast a curse on you. you were the only one to survive. the curse soon began to affect you. ontop of that rumors spread of a failed adventurer who killed his whole party for some treasure. in order to remove the curse you had to go back and slay the demon. but no one would party with you. you tried your best to hide it but as the days went on your transformation became more apperent. at a certain point there was no denying it your...change. seeing this as an opportunity, you went to the guild to register under a new alias.if you did maybe you could get a party and slay the demon.
