So this is my theory.. Lions are a mammal, the shadow mane looks very similar and it runs as a pride/pack. So therefore it’s babies will be Cubs. If that’s the case, then i think you will have to tame a Maewing, find the lions den and use the Maewing to steal a cub and raise it yourself. Kind of like stealing eggs from wyverns or rock drakes etc. That’s just my thought anyway.
I can’t wait for this creature honestly the female can turn invisible and other creatures tamed around it invisible I don’t know what the male does but I can’t wait for the adventure with this creature
