Tol Amn, situated within the Hutt Space sector of the galaxy, was a tempestuous and shadowed planet. It resided in the same named star system. This world was positioned along the Oktos Route hyperlane, a conduit linking it to both Toydaria and the Trax Tube hyperspace path.
Hutt species members utilized Tol Amn for foodstuff production, where serfs of different species were used as labor. The Galactic Empire's Oktos Zone Imperial Outpost on Toydaria, utilizing hyperwave signal interceptors, possessed the capability to observe lightspeed activity occurring at Tol Amn.
The first mention of Tol Amn occurred in The Essential Atlas, a reference book from 2009 that was written together by Jason Fry and Daniel Wallace. It located the planet within grid coordinates R-11.
