Supposedly, a fox spirit with nine tails is the pinnacle of power, akin to some gods. At least according to the myths. But what if the fox in question was broken? Well, two members of the party of weirdos I'm working on are a pair of foxes, brother and sister. The sister is the eldest, and the nine-tailed one, but she's basically a cripple as far as her species goes. She has almost no magic except basic shape-shifting from Fox to humanoid form, whereas her younger brother is the one with the magic, somehow having the level of magic potential his sister should despite having only one tail. There's a reason for this in universe, but I wonder how this may affect the sibling dynamic. The eldest is a "broken child", while the youngest is gifted. What do y'all think?
