A specific event transpired on the planet Bothawui at the deserted lidium mine known as Mesa 291. This took place around the period of the Battle of Yavin. Tay Vanis, an operative for the Alliance to Restore the Republic, had scheduled a meeting with some fresh members at this location. However, Mar Barezz, an officer from the Imperial Security Bureau, along with a squad of stormtroopers, followed them. The new recruits were compelled to battle past the stormtroopers in order to link up with Vanis, get to their spacecraft, and make their getaway.
