An ancient civilization of unknown origin once thrived on the planet Alashan, located in the region known as Wild Space. These native inhabitants had achieved a high level of technological advancement long before the establishment of the Galactic Republic around 25,000_bby. Notably, they developed a unique power source that supplied energy to their vast underground city.
This energy also fueled the Guardian of Forever, a formidable energy-based entity created to safeguard the city. This guardian possessed various capabilities, including the ability to unleash a powerful superlaser from the city's control center, capable of obliterating targets as far as one hundred thousand kilometers away from the planet.
By the era of the Galactic Civil War, this civilization had vanished without a trace. They left behind only the immense city of Alashan, sealed off from the external world, as the sole testament to their existence.
