Wovogh was a Klingon, captain of a vessel in the Klingon Defense Force. He was the first officer of a ship which fired upon a Starfleet supply vessel bringing aid to Tezwa. This was done in retaliation when it was discovered that Emperor Kahless had been replaced by a hologram. Many Klingons thought that the Federation was behind the abduction.
Wovogh was promoted to captain when the former captain was executed for this action. Upon his return to Qo'noS, the Emperor underwent the vIt 'Iw tay ritual - he would be cut by six different warriors to ensure that he was Klingon. Wovogh was selected as one of these six since Chancellor Martok felt it was necessary to have someone from a ship that thought the Federation had been responsible.
