So close. You were so close to acting like a rational and functional person. Also, why the hell did nobody pass down the reason for the curse, even within the royal family? I assumed they were unrepentant dipshits, but if ignorance was the problem, Rovel could probably have come by himself to tell them off too.
Also, also, why didn't Origin show up back then? Obviously she very reasonably hated this guy's guts, but at least show up to end the spirit's suffering. Are spirits not allowed to kill humans?
