The story of Peter March is not a happy one.

Born into poverty to parents who were abusive in their one ways, the one place where a young Peter could go in order to escape from his terrible life and awful family was the Wildwood Library. As he grew older he would often be found there daily, reading anything from comics to novels to history books. Despite more or less becoming a fixture of the library over the years, Peter was not the most socially or mentally healthy of people... and as such most tended to keep him at a distance.

When the murders and disappearances started to happen, Peter turned his attention towards more occult topics. In part to try and uncover answers, but also because it was a subject that he had visited a few times over the years.

Truth be told, Peter learned quite a bit about the situation with the Wildwood Library and the various entities that came to inhabit it via talking to the people that managed to get out of the building once the haunting truly began. However, rather then be of the mindset of going in to release the damned souls within and fight the Master, Peter's life was so shit and he had so little desire to continue on struggling with it that a different idea entered his mind.

Finding some dark rituals of his own and literally having nothing worth living for in his own mind if it failed, Peter entered the haunted Wildwood Library without anyone guiding or tempting him there. Finding a suitable spot within, he set up and performed his rituals which resulted in his death.

Only he didn't stay dead. Raising from the grave that was the ritual circle behind the Librarians desk, the now undead Peter claimed the Library as his home and the vampire couldn't be happier about it.

While he is still very much a weirdo by human standards, Peter has a social life within the walls of the Library. Unlike many of those wandering its shelves, he is not actually bound to the Library in any manner outside of the physical; If he wanted to, he could find the spell that opens the door to leave. He just doesn't want to.
