OOC : For the hybrid question, they’d most likely be banished, making them ‘non-kuros’ in the Kurosian’s eyes. Most likely however, they’d be hunted down shortly after banishment by other Kuros. For training purposes, for game, many reasons. But most wouldn’t want the shame of the Kurosian people to keep walking around.
PS – Also, YES. Some kuros could be bipedal. I don’t have a separate breed for em or anything.
