#it's protection from backlash from wielding more power than a mortal soul should be able to handle

The backstory for Alastor in this AU is inspired by the fact that I always suspected that Alastor was under a contract even before the show confirmed it. The way his powers work seemed to go beyond being voodoo or radio-based. My original headcanon was that he had multiple contracts with several ancient eldritch beings but for this AU, his contract is with Roo.

It was a contract that was established when he was a child as every member of his father's side of the family is expected to have a contract with Roo. On his father's side, Alastor comes from a long line of dark magic practitioners who say that they can trace their ancestry all the way back to Cain. For generations, they had been trying to create the perfect vessel through which the will of Roo could best manifest itself. However, whenever they thought they were close to achieving it, the person was driven mad by the power. This was until the birth of Alastor.

Alastor's mother was a voodoo practitioner while she was alive. She didn't know what Alastor's father was involved in when they met. It wasn't until Alastor's 6th birthday that she discovered the truth. Alastor's father had tried to induct Alastor into the family cult. Alastor had proven to be a good conduit, too good. The magic was too much for someone so young. It twisted and bent the child, the same way it bent reality around him.

Alastor's father had not expected it to go so badly. He had high hopes for his child. He knew Alastor would be a good conduit but he thought he would have time to teach him control, to make him strong enough to withstand it. He didn't. It happened too fast.

It took the combined efforts of Alastor's mother and father to get it under control. Alastor's mother spent the rest of that night praying and pleading with her ancestors and the loas to help her save her son. She succeeded but the cost was high and even though she succeeded in saving him, he would never be allowed to be a practitioner of her religion due to being marked by evil.

The relationship between Alastor's parent quickly fell apart after that. Alastor's father turned out to be from a family with plenty of money and influence so he was able to take Alastor away from his mother. Alastor only got to see her once a year until she died when he was 12.
