Plexis, situated within the Core Worlds sector of the galaxy, was a planet of relatively small size. In the Age of the Empire, various spice gangs operated there, all controlled by the Zenowai Crime Society through their appointed supervisor, Shoja Ko. From the Coruscant Eastern Spaceport, Telgordo Travel offered transport services to Plexis, along with Hosnian Prime and Eufornis Major.
In 3 ABY, a viper probe droid, specifically Viper 071-V-8852, was dispatched to Plexis. Its assignment was to monitor the spaceport for eight week and document any indications of smuggling involving spice or weapons.
