In 1484, the planet was the site of the last stand of the Vaadwaur before the Turei and their allies. The planet was the subject of a massive orbital bombardment by plasma bombs, which wiped out all life on the surface and caused a nuclear winter that rendered the planet uninhabitable for centuries. A battalion and their families, approximately 600 Vaadwaur, managed to survive in stasis underground, along with ships land vehicles, and weapons.
The surviving Vaadwaur were re-awakened by the crew of the USS Voyager, when they took shelter from the Turei on the planet's surface in 892 years later. At that time, the planet's atmosphere was still heavily contaminated with gamma radiation and radiogenic particles. Tom Paris described it as in "the middle of a nuclear winter".
