Sergoz was the first officer of the IKS noH'pach in 2376.

When the USS Euphrates was sabotaged by Prynn Tenmei the noH'pach assisted her. Taran'atar, who had kidnapped Tenmei, killed the party sent to help them and boarded the noH'pach. He killed both Sergoz and the captain with the second officer's disruptor. (DS9 novel: Warpath)
