Hi, Stelaphina.
Kingdoms are very large and contain groups that are into RP, and groups that aren't. It would be a good idea to visit the kingdom discords, get to know the dukes, duchesses, counts and countesses and their people. See where you fit in and who you click with. you'll find people who love RP in any kingdom.
If you're going NA-W server, may I suggest visiting Atravia Riftwood? There are those who are into RP in my duchy, for instance, it is important to us and very much supported and encouraged.
