Trihexalophine1138 was an experimental Separatist bioweapon that was to be tested on Naboo. It was carried on a Lucrehulk-class Core Ship, the Gahenna, which was destroyed above the planet Honoghr during a space battle. The resulting crash, coupled with the release of the toxin into the soil, crippled Honoghr's ecosystem. This event paved the way for the forty-year slavery of the Noghri by the Galactic Empire.
Allusions to George Lucas's first film, THX 1138, are made often throughout Star Wars material, and these homages have been officially acknowledged.
