Many generations past, a pack of wolves hunted in the lands we now know as Mulgore. There was plenty of prey and clean water, and, better yet, no humanoid races existed to threat their well being.
Still, the wolves longed for bloodshed, even when their bellies were full. They were bloodthirsty unlike the other noble packs. Many outsider wolves perished under the fangs of the vicious pack, which fought only due to their lust for the precious life fluid.
One day, the terrible Alpha who had been leading the pack in their ways of destruction perished. A new Alpha took charge and, although he had been born with a pure heart, he had been corrupted by his pack's constant violent acts.
The new Alpha had not been completely blindfolded, however, and thus he had to make a choice: either stay in the comfort zone, letting the wolves of the pack do what they did best or attempt to change their ways and kill those who refused, even if that meant the extinction of his own pack, or his own death.
After pondering, the Alpha was wise enough to choose the hard but most rewarding path. He fought bravely and killed many of his peers, but finally the survivals' eyes were opened and they became another pack of noble beasts.
Still, there were things left to do; codes of conduct among the pack were changed and forgiveness was asked to the other packs. In time, the once murderous pack proved itself and the other packs conceded the forgiveness they deserved with great piety.
The lesson of this tale is simple, but important. It is necessary sometimes to leave the comfort of our habits if that is going to make those around us, from our family circle to the ones we have not yet met, happier.
