Zonek Karle was a Cardassian sleeper agent inside Federation space that used the alias Jeremy Gleason and piloted the Solanco. In the year 2374, Karle was sent on a critical mission to deliver a Changeling that had infiltrated Starfleet on Earth and gained access to codes that would shut down the minefield in front of the Bajoran wormhole to Terok Nor. (*) realized that these codes would allow the Dominion to end the war and its feast, so (*) caused tension among Karle and the Dominion contingent, eventually ending with Karle setting the ship on a course for the Hunyadi Rift, killing the Changeling, and being killed by the Jem'Hadar troops. The Solanco would continue on its course to the Rift and be lost there. (ST - Tales of the Dominion War short story: "Night of the Vulture")
