To be honest, the Kamal as refered as way too many things to really think well of what they are.
Yesterday I spend half afternoon researching, I've an RP event to do, and I kinda need to know how the Kamal looked like for certain things to make more sense. I've looked everywhere on how the Kamal looked, some people just say they look like yeti, because "snow demons".
It's so frustrating to have a character who fought the Akaviri in their invasion, yet have no idea how they look like xD Then in RP you're asked: "How did they look like?" and well, you can't really answer that because you've no idea. Does it really make sense? That there are -tons- of books, written reports of people in the Invasion, and nobody gives a single description. Reports that are supposed to go from soldiers to their superiors, why not describe the Kamal? I wish the loremaster could give us some more hints, or directly a description ._.
