I will bring you into my debt...
Viciously irritable and rather annoying in his spite for the others. He hates to be around them, much preferring to lurk in his misty maple wood at the border between Life and Death. He is absolutely obsessed with death; it is both what got him caught up as a Guardian, and what got him killed.
He uses Mender to heal, of course. His weapons are scalpels.
Working as a doctor in the underground, he healed assassins and changed appearances for those who needed to disappear. When Avis saved his life, he was forced into Guardianship by the debt. He never got to repay that debt, or put Avis into debt as he so often said he would, because one of his gambles got him killed first.
