If you're still looking for partners, I'd love to explore the Zuko/Katara pairing with you! It's been years since the show ended, but I'm still not over it.
I must admit, I'm really in love with "Hearts of Gray", because I haven't done an Old Republic styled Star Wars roleplay in a very long time, but all of your plots look fantastic. I'd love to hear from you if you're still looking for partners!
