Rov, Son of Pekdal was a Klingon member of Klahb, and in 2379 led the attempted takeover of the Federation Embassy on Qo'noS. He had been hired as a kitchen stewart at the embassy sometime in the month prior to the takeover.
It was Rov who insisted that they must capture Worf and attempt to use him as a hostage. Worf was not captured in the initial assault, but Rov went ahead with his plans anyway assuming that he soon would be. He contacted the Klingon High Council and demanded that Martok step down as Chancellor, that the hologram impersonating Kahless be deactivated, and that Empire declare war on the Federation.
During the takeover, Rov personally killed Damir Gorjanc, an embassy employee, and Vark another leader in Klahb. Vark was angry with Rov when he found out that Rov refused to serve in the Klingon Defense Force during the Dominion War because they would not grant him the status of an officer and wanted him to serve as a bekk.
Eventually, Worf was able to regain control of the security system and flood the building with anesthizine gas knocking everyone unconcious. Rov was able to escape in the confusion. He later turned up broadcasting his demands to the entire empire from Pheben V. The base was destroyed by a Klingon fleet patrolling the nearby area; however, Rov was likely using some sort of remote transmission device as his body was not recovered.
