Lettow

Lettow was a Core Worlds planet. After leaving the Jedi Order in 24,500 BBY, the Jedi Knight Xendor founded the Legionnaire Academy on Lettow for studying alternative Force-user traditions. Other like-minded individuals who came to follow Xendor named themselves the Legions of Lettow, and the group eventually came into conflict with the Jedi. After Xendor's death at the Battle of Columus, Jedi armies attacked the Legionnaires at Lettow, who held them off long enough to escape beyond the borders of the Galactic Republic. Over the subsequent millennia, Lettow became a legendary lost world.
