Gelnon

Gelnon was a Vorta male who lead Dominion forces during the Dominion War. Among the Jem'Hadar under his command was Kudak'Etan.

In 2374, Gelnon's fighter attacked and damaged the USS Defiant (NX-74205) (I), which was engaged in a scientific study of a subspace compression. Gelnon's soldiers boarded the ship and took the crew prisoner. Gelnon left Kudak'Etan in charge to bring the Defiant to a Dominion base, while his ship launched an attack on the dilithium mines of Coridan III. 

Several weeks later, Gelnon formed an alliance between the Dominion and the Orion Syndicate. Gelnon's plan was for the Syndicate to kill the Klingon ambassador to New Sydney, an opponent of Chancellor Gowron who wanted the Klingon Empire to withdraw from the war. Gelnon believed that the use of Klingon disruptors would make it look like Gowron had ordered the ambassadors assination and turn him into a martyr for the anti-war cause and the dissolution of the Khitomer Accords. 

Gelnon continued to lead Dominion troops in the 25th century.
