Bet she's a dragon lol, or some sort of horned mythical beast.

Or a goat

goat isnt really mythical and also not necessarily healing, though I did think it was a possibility too-just not likely

It actually is very mythological, as it representants demons :)

yeah but in the sense of this story, where livestock are generally common, I wouldnt figure a goat would be considered mythical. I mean "rare". Dragons were listed as the top of the triangle of rarity in this story, meanwhile average animals(such as livestock and herbivores) seem to be a lot more common, and less powerful. Unless its a special type of goat, I doubt she'll be a goat.
