At least part of the planet was covered in rocky desert, dotted with large, light blue constellations of gemstones. Tall cliffs loomed over the landscape, some of which had been sculpted into enormous statues of notable Sith. Under the Galactic Republic, some of these monuments were destroyed to make room for a gemstone quarry. The Republic also operated at least one settlement on the planet.[4]
Begeren was seized by the Sith Empire some time prior to approximately 5,000 BBY.[8] The Empire set about constructing massive monuments of noteworthy Sith alchemists, warriors, and philosophers. Slave labor was used to build the statues, and an estimated hundred thousand slaves died before the work was completed.[4]
In the years following the Sith Empire's defeat in the Great Hyperspace War,[9] Begeren was claimed by the Galactic Republic. A governor was installed to oversee the world. At least one gemstone quarry was constructed to exploit Begeren's precious natural resources. This mining industry came at the expense of the Sith monuments, which fell into disrepair.[4]
The world remained under Republic supervision until the year 3,678 BBY, when it was invaded by the resurgent Sith Empire as part of the Great Galactic War. Despite suffering losses, the Imperial Army—aided by the Sith Teneb Kel—defeated the Republic and killed its governor.[4]
Under the Sith Empire, an estimated hundred thousand slaves died while working on Begeren's monuments. One of the Republic's governors was of the Advozsespecies, while at least some of its soldiers were Humans.[4]
