Or in other words with such a short prologue, pretty much one paragraph for the child, you've made her dangerously Mary Sue.
Then there's the fact you really rushed and vaguely set up the land, and the clans; you could have focused on them more, and then finally, nearing the end of the prologue, set it up to where Eva, the lone survivor of her massacred clan, was found by the Mightyena, though it confuses me.
You have it many Mightyena are there, yet have it only one was smart enough to seek aid? Why did they only try and rescue the one babe? How was she overlooked? It may be a Prologue but you left it so vapid and up in the air it just screams you're setting yourself up for a Mary Sue.
I suggest heavily revamping this first, before making a first chapter. And reading Advice for Aspiring Authors, and taking a Sue test, to be sure your character avoids becoming a sue of any sort.
