Hundreds of millennia ago, seven tribes of pegasi journeyed to the south pole of the planet Equus. In a world of hostile predators, these primitive ponies decided to utilize the bitter cold of the arctic as a defense against the outside world.

These tribes were known as the Ullens, the Cristali, the Izens, the Glacens, the Whittox, the Glisseaux, and the Iafins.

This is the story of those seven tribes, and how they developed over time to become the prosperous nation known as Ulluria.
