In 1484, the planet was the site of the Vaadwaur's last stand 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 of 600 Vaadwaur managed to survive in stasis underground, along with ships and weapons.
The surviving Vaadwaur were reawakened by the crew of the USS Voyager, when they took shelter from the Turei on the planet's surface in 2376. At that time, the planet's atmosphere was still heavily contaminated with gamma radiation and radiogenic particles. (VOY: "Dragon's Teeth")
