This is a newer interpretation of the Álàntúr.
The first interpretation was a more humanoid creature (there's a picture of it in my files) but I thought it would make more sense to give them the form of an aquatic creature. After all, they were born out of water and never really left the sea.
So I made them this way: like an enormous dragon-like water snake. I know you can't really see any proportions in this picture, but if you read the description of the first interpretation you'll get the idea. It should say enough that they created a structure many times the size of the earth to live in.
I'm not sure if I'll keep this interpretation. Perhaps I'll change it again later on.
