During the recent Federation/Klingon
conflict, Cpt. Cantrell and a few other
members of the command crew of the
USS Serendipity were assigned on a covert
mission into the heart of the Klingon Empire.
Under the alias K'Trel, his mission was to
probe the areas around Gowron and find a way
to insert Cpt. Sisko so he could expose Gowron
as a changling and restore peace between the
Empire and the Federation so that together
they could fight the real enemy: the Dominion.
