Skeen Plague

The Skeen Plague was a plague that scoured around the surface of Aantooine sometime between its habitation by the Aan and the Tooins and that of the Spalgar. It resulted as an unfortunate side effect of the Serpent's War between Humans and Skeen. After the Humans won the war against their opponents, they chose to not bury the dead Skeen as they felt it would dishonor their own fallen people. The rotting carcasses produced a foul stench that, over a period of three standard weeks, resulted in a deadly fog that spread from across the plains of Crom to the farthest continents, via plague-carrying passengers to Ulaia and Wiesia.

Ninety-five percent of the planet was affected by the plague, with few survivors in the most remote regions. The stories of the Skeen and the Serpent's War were lost to history as most was passed down orally between small cave-dwelling families. What remained on the surface was slowed taken away as the planet entered a long ice age, with glaciers filling the valleys. They would be hardly any evidence that the Skeen even existed. Most Aan and Tooin settlements would also be heavily weathered before the arrival of the Spalgar. The Humans would be found in sporadic numbers, but not large enough to be considered an influential force on the planet again. Only once the Spalgar began to redevelop Aantooine, did the Human population start to revive.
