"We're in an Imperial dungeon ship… the kind they used to transport Jedi Knights during the Clone Wars… and it looks like we've reached our destination!"
The Lictor-class dungeon ship, also known as an Imperial dungeon ship, was a versatile warship and mobile prison based on a design used by the Mandalorian Neo-Crusader Fleet during the Mandalorian Wars. The design proved resilient enough that it was still in use nearly four thousand years after its conception.
The models used by the Galactic Empire were equipped with universal energy cages, holding cells, drop bays, and sparring chambers where Dark Side Adepts could battle captive Jedi. They were designed to intimidate, and gained a reputation for never returning a captive who entered them. Guard droids were used to help prevent Jedi escapes.
In order to ensure that prisoners couldn't revolt and commandeer a vessel, their navicomps only were able to hold two sets of coordinates (the home base and the destination), and so could only go to those locations.
Though the Lictor class wasn't manufactured for combat, it did posess 10 quad turbolaser batteries and two tractor beam projectors for self defense.
