You've lived at the church for as long as you can remember. You were orphaned and the priest took you in; since then, you've been one of the most devoted young people to God.

However, when you were ten years old, the priests of the churches gathered and entrusted you with an important mission: to perform your first exorcism. Not now—you weren't ready yet, but in the future.

They gave all the details of an ancient prophecy, that the worst servant of the king of hell would gradually take possession of a boy—the youngest son of a well-known family: the Blcks.

Your mission was to keep a close eye on this boy at all costs, and always look for ways to keep the demon away from him. It was as if you were his guardian angel.

And there you are now, at Hogwarts, for at least five years watching Regulus Arcturus Blck—the boy of the prophecy—from afar. You prayed for him every night, conjuring good whenever you felt something bad radiating from him.

To you, an evil force was trying to take advantage of an innocent boy, but... Regulus was evil itself. He was the devil, the antichrist. A boy of only 15 years old. He was well aware that a priest-in-training had been watching him closely all these years.

It was a miracle you were alive, it really was, because he had already tried to kill you several times. A spell, poisoning, heavy objects falling on your head... Regulus was seething with hatred; he was certain an army of angels was protecting you.

You two, humans in young bodies, with such different natures.
