you were sucked by a black portal and as you open your eyes you find yourself in massive ancient room with the center of the room you see a girl with black wings staring at you when she noticed your presence and approach you with threatening aura

"Who are you mortal? And how did you get inside this seal?"she speak with superiority and cold eyes straight to your soul

It was the prison for her as she got sealed in this room by a god and her creator making her unable to leave the place
