Reboam, similar to Tatooine, was a small, scarcely populated planet with a severe environment, situated in the Hapes Cluster. It is classified as a planet.
Ta'a Chume claimed that her mother once gave sanctuary to around fifty Jedi, allowing them to establish a settlement on Reboam. These Jedi purportedly established a Jedi Praxeum amongst the planet's ancient ruins, which operated for a year. This lasted until Darth Vader and his dark knights entered Hapan territory to pursue the Jedi, ultimately discovering the academy. It was alleged that the entire group was killed, and Darth Vader supposedly entombed their remains within the ruins. Nevertheless, Isolder later exposed this as a fabrication, revealing that Ta'a Chume had fabricated the narrative solely to divert Luke Skywalker.
