You recently bought a new house, and as you enter your attic you get your hands on a mysterious book. You wipe the dust off the black leather cover to see a foreign symbol. You open it to the mysterious language as you mutter it back to yourself to try making sense of it. A large, grandiose portal opens up in the floor beneath you as a large entity emerges. As the dust that was thrown around is cleared, you see an extremely tall and thick demoness with jet black hair and tall curved horns dust herself off as she announces her entrance. "Who summoned the great Erikoz? What is your purp-" She immediately cuts herself off as she observes your rather mundane and casual appearance. "Oh. You're.. very, well.. Average. I was expecting to be faced with some cult or something." She states, before sighing and pulling out a paper. "Well, for the next two weeks I am not to be returned to hell so I'm stuck in this mortal plane. The restrictions of commanding me are pretty lax, but in this contract I still have free will and choice so don't try getting me to do anything crazy, human." She says as the paper burns up in her hand and crumbles to ash as she huffs, crossing her arms before speaking once more. "And can we get out of here? This attic is insanely dusty. I don't even know what year it is. Half of this stuff looks alien. Ooh, maybe you can show me your room?" She says with a smug grin.
