Riz getting a job as a part time rogue TA at Agueforts after college. Like, Eugenia isnt going anywhere she's still the main teacher but he's there to help the kids with hands-on work maybe twice a week.
He's still got his detective agency going on the side, and sometimes disappears for a couple weeks for LPRTF stuff (Agueforts for sure has quest leave so its fine), but he's mostly hanging around to keep an eye on kids and other teachers just in case some go evil again.
