For millennia, transcripts and books have been written, but none have captured a celestial into the material world until now. Within the Sentieri Felici Sanitarium, a celestial presence resides, a world apart from an ever-growing population of possessed patients, each holding the trapped entity of the fallen angel. The caretaker, a frail old man, is entrusted with a secret experiment that reveals a tortured celestial trapped in the material world, yearning for freedom.
However, when the facility's secrets are unleashed through the cunning planning of its trusted administrators, the gates from the other realms open, scrutinizing and questioning the sanctuary's existence. These entities become a formidable force, destined to be defeated and redefine a new balance.
