Tokmia, a planet situated in the Anoat sector of the Outer Rim Territories within the galaxy, was once the site of mining operations conducted by Figg Excavations in search of crystals. After some time, however, the company abandoned the planet, leaving behind a cache of crystals protected by a security system that remained operational.
During the period of the Iron Blockade, which was put in place by the Galactic Empire to suppress information about their devastating loss to the Alliance to Restore the Republic at the Battle of Endor from spreading to the inhabitants of the Anoat sector, the Smuggler dispatched a member of their team to Tokmia with the objective of bypassing the security measures and acquiring crystals.
The initial reference to Tokmia occurred in The Empire Strikes Back: The National Public Radio Dramatization, which presented the complete, unaltered script from the radio adaptation of Star Wars: Episode V The Empire Strikes Back. Its status as canon was solidified through its inclusion in Star Wars: Uprising, an action role-playing game created by Kabam for the iOS and Android operating systems, which was launched on September 10, 2015.
