This is a sketch of an older VIP vessel used during the "Great Purge" to ferry cardinals and their inquisitors around the Dominion. Although not heavily armed, they were almost always accompanied by other Dominion warships. They were equipped with gravity harness drives and were able to descend to planetary surfaces - some only a few classes of the day the day that could. The prow of the vessel was dedicated to the cardinal's sanctum, an expansive space in which the cardinal or other VIP would be able to receive dignitaries, conduct negotiations and meditate. A typical Cardinal's Frigate would carry a crew of 100 as well as 50 inquisitors and was equipped with a gaol and inquisition chambers where confessions were heard and the guilty punished for their crimes.
Few Cardinal's Frigates remain as they are outdated, although some of these ships can be found far beyond the rim doing service as VIP transports for crime lords.
