Harrow was born into a household of 4 siblings. When he was younger, Harrow was attacked by a wolf while hunting with his dad. He grew sick rapidly, but was unable to figure out what it was until the effects were too late.

Harrow's memory became hazy- and he began to lose a feel of the world around him, until the only prominent emotion to occur to him was a strong, burning insatiable hunger.

He was investigated by The Medical Council of Vastern, where he was diagnosed with Lycanthropy. Unable to determine what to do with him, he was originally meant to be dispatched; but the Guardsmen Sorin chose to instead control, utilize, and harness his abilities in order to track down the illegal use of Magic.

Harrow is bound by runes to obey this command, only able to fulfill the command by the contract ending, or by curing his Lycanthropy.

In order to cope with the feeling of hopelessness, Harrow grew into this role, and projects a brash, overconfident, and obnoxious personality. He is invasive to cope with his constant curiosity of the world, and often drives others mad as a result of it.

Harrow's curiosity often causes him to step out of line, and it is typically up to Sorin to push him into calming down.

During one mission, Harrow encountered a gorgeous Friesian with a thick black coat, infected with a similar corrupt magic that consumed his being as well. He sympathized with her, and as a result the two bonded. After being permitted to keep her, he named her Misty.

Harrow often feels as if he is undesirable, unloved, and self-isolates as a result. He doesn't find any problem with this, however, and continues to lean into his own projections to cope; Resulting in him failing to admit that he desperately wants to be cared for, and would give anything to feel that way.

Due to the corruption of his magic, Harrow cannot drink water because it turns to ice from his touch, he handles this by eating ice, but this does have it's consequences.
