The mercenary ship of Antonia Chillingsworth.
The Kublai Khan is a mercenary ship, a plantation operation the ship loads mercenaries at port, as many as it can carry, keeping them frozen in cryogenic stasis.
Then the ship, and its mercenaries hunt down hundreds of bounties filling the cryogenic storage with as many as it can. Presumably the bounties are taken back and cashed in, with certain bounties being kept for Antonia Chillingsworths private collection.
The Ship is built to hold hundreds of people in cryogenic storage, prisoners kept opposite of mercenaries. There is a private room called The Conservatory that keeps certain prisoners alive frozen with their minds still active as gruesome trophies. There is also a flight-deck on the ship that carries at least five smaller ships.
- The ship is mentioned on the Blu-Ray copy of the Chronicles of Riddick in the u-contol menus encyclopedia, where its name is misspelled as Kublai Kan.
