A human settlement on Unzervalt aka Vela I
Unzervalt is a planet in the Vela system. The name "Unzervalt" was given by its Human colonists; this meant "our world", likely originating from the German "unsere Welt". Captain I. Burton of the Star Control Cruiser Tobermoon took refuge here after escaping a Hierarchy attack during the Ur-Quan Slave War, discovering a massive Precursor installation hidden beneath the planet's surface. She later returned leading a Corridor Nine-sponsored science mission to attempt to salvage the ruins; when the mission was recalled and the Tobermoon called back into combat service with the disastrous Alliance defeat at Rigel, most of the expedition remained behind to oversee the reconstruction of the station and the creation of The Flagship.
Unzervalt has a variety of native flora and fauna. Some of these, after identification by the Precursor databanks, were key in the survival of the early colony. These include the blue-flowered Iccamullon, the six-legged Ortog, and the winged Libixx. Some colonists that ventured far beyond the original colonies came back with tales of additional, strange native life-forms.
The Captain was born on Unzervalt, and it was he who discovered how to operate the facility and the Precursor starship. An expeditionary force was assembled for a voyage back to Earth. Star Control II picks up when The Captain arrives at Sol with his Flagship. By backtracking his path, an Ur-Quan Dreadnought discovered the colony shortly after The Captain's departure, and erected a slave shield around it. The Dreadnought can still be found in the system in Star Control II.
