Yep. The thread is here.

Before you post, though, let me make some edits to my post. Right now it's written like it's just an ordinary fire-breathing dragon.

How much do you know about Fallien? I don't know if you've poked through the region info at all, but if you haven't, I can give you a quick rundown on what you need to know.
