Derhart, Dearheart, various derivations of such. Yes you are correct. Extraordinarily mountainous and rough coast, deciduous and pine forests. For climate Im thinking: marine west coast climate or oceanic climate. In the Köppen classification, much of the coast is Cfb—temperate. But I could be completely wrong. Id have to go back to my maps and work it out. So you may want to avoid climate and plant specifics.

Haha yeah I saw that too and couldn’t help having the same thought. Also, most of those little Queendoms are eponymous. Only I think that I was thinking it’d be said closer to ‘sigh-lean’ rather than the normal pronunciation of Celine.
