"Contractors, READ THIS FIRST! Use the Thorium charges in this locker only as a last resort to clear a blocked door. This structure is very old and unstable, and cave-ins could damage or destroy the artifacts we were sent here to collect."
Datapad found by the Jedi Exile on Korriban[src]

Thorium charges were high-explosives used for demolitions. A thorium charge was more powerful than a comparably-sized thermal detonator.

Akkere had some in his possession in 3951 BBY, and may have sold them to the Jedi Exile. Some were also carried by contractors who explored the Sith Academy on Korriban.

Behind the scenesEdit

The player character in Star Wars: Knights of the Old Republic II: The Sith Lords can obtain thorium charges from Akkere through dialogue near the end of the Dantooine mission or by killing the merchant, and can find them on Korriban accompanied by a datapad highlighting their destructive nature. The charges are in a nearby footlocker, and if the player character chooses to "bash open" the footlocker instead of cracking its lock, the thoriam charges detonate, causing damage to all party members nearby.
