Ahh finally someone that's at the very least read it. Over the last 5 years I have posted info on dozens of different boards, including MMORPG.com, and rarely does anyone ever bother to say anything. I did however get bashed like a red headed step-child on mmorpg on stuff that wasn't even related to the game, but I digress.
I'd thought about that, I even remember seeing that episode of Dr. Who and it got me to thinking, but still it's not quite fish-like enough. I had actually thought about a mask like the picture above and little anti-grave floaty things that would allow them to swim through the air. I really want them to be more "alien" than my other races but I just can't see it in my head and still being reasonably playable.
Anyway, thanks again, you've no idea how happy it makes me that someone actually read through even a portion of it.
