Hello and welcome! There are some RP prompts up in the roleplaying areas of the forums that you might be interested in. I think "Secret Life of a Coterie" is still looking for people and that one might be up your alley given those search terms. There's a lot of other things there as well you could get interested in as well, and I'm sure a lot of people would be happy to have you!
If you're on discord at all, the server for STC is a great place to hang out, and you're welcome to come chat with us there too. Otherwise, feel free to wander around the site as well, and let us know if there's anything we can help you get started with. Hope to see you around!
