So I had this idea a while ago where depending on your kings karma your king will either get a halo (like all lions currently do) when they die for good karma or devil horns if they had bad karma.

For lionesses it obviously wouldn't work in the same way but maybe it could be personality based or player chosen since I know some people may have say an evil personality lioness but have written a back story of the lioness being a good lioness instead. If anyone has any other suggestions as to how it could transition to females since they don't have karma feel free to drop your idea below!
