When it comes to the Dragon-kin, I'd much prefer if you went with Dragonborn. It's the same concept but without wings. As for the leviathan, I have to say no to that. It's simply to monstrous.
@Kazemitsu As said in the CS, most fantasy races will be allowed. From things like Elves and Dwarves to Dragonborn (Like DnD not Skyrim) and Tieflings. There aren't many races we would say no to, as long as they are humanoid.
Hey, I've been looking to bring in some new blood to our table, but I live in the middle of nowhere near Memphis. Not a whole lot of TT fans in the Bible belt sadly, or at least it's hard to find them.
Don't worry about it. I'm happy for the attention though.
I love these kind of in the dark type roleplays. I GM Pathfinder with friends and family but they hate not knowing things so I rarely get to do these anymore.
