Sol Tres

Sol Tres is the third planet in the Sol System. Tres, as it's called, is a former hospitaple world, now only a dead rock. The one known only as the Gnarly Old Man is said to have come from the planet, long before it's destruction.

History
Seeing as the Gnarly Old Man is the only known former resident, the history has been documented from his words. Apparently, Tres was once a lush, beautiful world. In the centuries before his birth, the world was constantly at war with one another. Finally, the people of Tres, or Tresians as they have been nicknamed, came to peace. Being at peace, the Tresians began looking to the stars. They started work on a Space Program. The Space Program was completed when the Gnarly Old Man was around thirty. He voluntered for the Grand Tour of the Stars.
