Reboam was a planet located within the Hapes Cluster which was noted for being a small world with a harsh climate that was relatively uninhabited and was comparable to Tatooine. According to the claims of Ta'a Chume, her mother once granted refugee of a group of up to fifty Jedi to settle on Reboam. There they formed a Jedi Praxeum by the ancient ruins of the world which ran for a year until Darth Vader and his dark knights came to Hapan space to hunt down the Jedi where they uncovered the academy. The group were all reportedly slain and Darth Vader was said to have sealed their remains in the ruins. However, this was later revealed by Isolder to have been a lie as Ta'a Chume only said the story in order to distract Luke Skywalker.
