Commander Dolim reclines in his thermal chamber.
Thermal chambers are extensively heated quarters used by Xindi-Reptilians on their ships. Because the Reptilians are cold-blooded, they frequently require the extra heat provided by the chambers' massive sunlamps to keep them energized and active.
Commander Dolim had a personal thermal chamber on board his vessel in 2154. (ENT: "The Council", "Countdown")
