The Jedi Enclave of Dantooine was a Jedi Academy for the Jedi Order to train new members without being disturbed by the Sith Empire. Built by Vodo-Siosk Baas, it served in that capacity until one of their fallen Jedi Knight, Darth Malak, bombarded it and the surrounding civilian buildings.
Ever since the attack, the citizens of Dantooine have hated the Jedi for bringing war to their peaceful planet. Although the Jedi Enclave was in ruins, it was still a place for study of the Jedi arts.
Recreating the Jedi Order
After the First Jedi Purge the newly trained Jedi, taught by Surik, began using the abandoned Academy to recreate the Jedi Order.
