When the nation of Nyyx was in its early days, it was frequently attacked by wild, savage animals. The kingdom was getting low on inhabitants when the Guru Klyxxnym prayed to the Great Wyrm to save them from this terrible fate. He prayed like he had never prayed before. The Great Wyrm heard him, and He answered with an army of Shades. The next night, when the hordes of animals attacked the kingdom, the Shades rose up out of the ground, slaughtering all of the animals in one foul swoop. To this day, the Shades have been the Penultimate line of defense.
When the animals were slaughtered, the people of Nyyx feasted for weeks, until they got so sick of the taste of meat that the Archlord decided to ban the purchase of meat for all but himself and his Mate. He even went so far as to implant genetic coding into his people to make them hate the taste of meat.
