The poor dragoness stood in fear of the most evil creatures ever, Ponies! Why would a dragon fear a pony? Same reason a human would fear a Brazilian Wandering Back or a Black Mamba Snake. Ponies are the most evil creatures ever, they use their magic to enslave the minds of dragons. An innocent dragon was forced out of his cave by some jerk pegasi.

....is what this dragoness thought anyway...of course she did not get all the details and thanks to her village's propaganda, believed ponies to be dangerous creatures with nasty intentions.
