Ick... This is how I know when I'm losing my groove again. I will post up the coloured version once I get it back.
They may be intelligent creatures, but they are still wild beings. I based their nature on lions - The males are larger than the females, and their only natural enemy is themselves. There can only be one male in a school of these folks, and he has to be able to fend for himself and his family or else another male will swim in, challenge him, and claim his throne. He will chase his male pups out once they are about to reach maturity. The older the males are, the bigger they get, and the more faded their colours will be.
