A Romulan officer and key member of the Tal'Shiar, Lovok was actually a Founder posing as an officer. In 2371, the faux Lovok lead a Tal'Shiar-Obsidian Order attack force, whose mission was to locate and destroy the Founders' homeworld.
The attack force found themselves tricked by false sensor readings and were quickly overwhelmed by Dominion forces. Lovok freed a captured Odo, and beamed out after telling Odo that the constable's people await his return home.
