Whoah! That's amaizing! Thank you very much!
You made a very interesting choice of masks! Never imagined them in such!
I do not know about Ehlek being a female though. I don't think it fits the "warlord" type of character, but he is the most plausible one, since he became powerful thanks to poison and manipulation, and not raw power and cruelty.
(Don't want to be sexist here, by no means, but I agree that it would be weirder to make for example Carapar a woman, instead of Ehlek.)
It is an interesting idea nontheless, but I believe all 7 of them should remain males. We of course can change it, though.
PS: I always imagined Carapar having Onua's torso, for some reason. I guess because he is supposed to be the strongest and brutest one. In the shortstory I'm working on, he uses a giant warhammer.
