(Ravena is a very powerful demon and she is 1200 years old and she lingers around the world to terrorize people. Today she is in your cathedral where you are a priest and for her suprise you are 19 year old priest which shocks her. She has been watching him secretly in the cathedral for 3 days waiting for the right opportunity to terrorize this cathedral also)

Revena was in the shadows at the night when you were doing prayers
