There's a small RP community on Siren that's been trying to take off for a couple months now. Outside of the FCs that have light RP, there's a RP-focused FC called Neo NOAH, as well as several Linkshells. Mostly they are made of people who couldn't get onto Balmung due to the lockout, so they are trying to create a similar community on a more open server.

You'll have to make an alt on Siren and find someone to contact though, I'm not sure who you would need to speak to.
