I'd try finding your way to Seaside Grove. That's definitely where I saw the most "random roleplays." A snow leopard once ran off for now reason because I tried to hug her cubs, haha! In case you don't know how to get there, it's that random path of rocks in Lonely Cave that lead to the portal. There's also a portal in The Grounds. As stated before, Cherika is also a good place to hang around, being it seems to have become a sort of new Fluorite-- mappless RP central.
But, if you still can't find anyone to roleplay with, I'm always open for some dramatic roleplay, haha!
