Life is short. Mess with me and it's even shorter.
Xypher redefines the term evil so much so that M’Adoc was forced to put him down. As a Phobotory Skotos, there’s nothing he likes more than to scare anyone he comes into contact with. There is no kindness. Brutality is all he’s ever known and it’s all he understands. So when Hades makes a bargain with him to stalk the gallu demons and help Sin defeat them, he takes the bargain even if it does mean spending a month as a human. It’s not a month he relishes, but anything beats being tortured in Tartarus.
At least that’s what he thinks until he comes into contact with the one human who may be scarier than him.
