There are Mulhorandi (both NPC and PC) in Kohl, though activity is a bit low. It wouldn't be too extraordinary to find out that there are Mulhorandi living in Kohl after some
big events in Khem. (fyi Khem is a non-canon island in the Alamber Sea off the coast of Mulhorandi and is for all intents and purposes a part of the Mulhorandi nation; something your char would probably know!)
I can say for certain that I know one PC that would definitely help. Unfortunately I'm not on her that much, but we can arrange a meeting via PM! She's very hard to miss and lives in Kohl (for reasons that would be completely obvious once meeting her
)
