Gor Thot Gor was a Breen soldier in the 24th century Breen Confederacy . He became known for beginning the relationship between the Confederacy and the Dominion , signing the Breen - Dominion Alliance . History . Gor became a thot by 2375 . He was approached in mid - 2375 by the Female Changeling for an alliance between the Dominion and the Breen , as the Dominion War , fought between the Dominion and the Federation Alliance in the Alpha Quadrant , grew to a stalemate . After several subspace communication s , Gor agreed to the proposed alliance and served as the Confederacy ' s first representative to the Dominion , foreseeing an opportunity for conquest as a share of the defeated Federation Alliance . Gor traveled to Cardassia Prime to sign the treaty between their governments . En route , his ship captured Lieutenant Commander Worf and Lieutenant Ezri Dax , who had been stranded on a planet in the Goralis system . Gor decided to bring them as a gift to the Dominion when he boarded Weyoun 7 ' s attack ship to meet Weyoun , Damar , and the Female Changeling . ( ) With the addition of the Breen forces , the balance of power in the war was shifted to the Dominion ' s benefit , and , for that , Thot Gor was given a lot of favor . He negotiated a secret protocol in the treaty for territorial concessions from Cardassia as well as access to all Cardassian database s , each over Damar ' s protest . He oversaw the Breen forces , and also was given authority on all military recommendations , including from Damar . This incensed Damar greatly . Gor went to work right away , recommending taking advantage of several weak points on the Romulan border , including the Unroth system . He also ordered a daring Breen attack on Earth . He later oversaw the Second Battle of Chin ' toka , which was a remarkable victory for the Dominion . ( ) Through these successes , Gor had an even closer relationship with Weyoun and subtly insulted Damar . Damar warned Gor that the Breen would be blamed , just as Cardassia currently was , for any failures . Gor defiantly did not expect any failures to happen . He also intrigued Weyoun – for example , by saying that was not particularly cold but then not revealing to him the real reason for refrigeration suit s which the Breen soldiers wore at all times . Gor watched , along with Weyoun and the Female Changeling , as Damar sent out a transmission calling for the beginning of the Cardassian Liberation Front . Gor was subsequently tasked with finding Damar , no matter the cost . ( ) Following the retaking of Chin ' toka , Gor was succeeded by Thot Pran as commander of the Breen forces . ( ) Appendices .
