I was going to ask if he became a member of the Royal Guard. If so, he could be in the city on duty. He could request transferring to the Hunter's Guild.

Or he could be on a hunt by himself or with a group of other guards. Hunting whatever you want to write about. I want to move the hunters back to the city to gather everyone together again but we have to wait until the fight with the vampires is over.

Well I doubt it. Do they take a suicidal depressed man who killed his entire family save his daughter when they all turned to be mad vampires? It could work though, if the whole thing happened recently and he's leaving the Royal Guards full of grief and personal demons.
