In 2371, Korinas represented the Obsidian Order as an observer during Commander Benjamin Sisko and Gul Dukat's search for the USS Defiant, which had been captured by Thomas Riker and the Maquis from inside the Cardassian War Room of the Cardassian Central Command.
Korinas questioned Dukat's abilities during the search mission and also ordered to secure all intelligence information with a level four classification and above. During the search mission Korinas threatened Dukat and the starships of the Cardassian military when they headed for the Orias system where the Order secretly and illegally built a base protected by Keldon-class warships.
Background information Edit
