Shakalak

The Shakalak was a Romulan warhawk under the commander of Commander Zanex. The ship was the only one of three warhawks to survive ambushing a Vulcan frigate. It escaped to Federation space, at which point it was repaired. The Shakalak was short a tactical officer after fighting the Vulcans, so Lieutenant Commander Tovar took the opportunity to escape his troubles on the USS Anomaly by volunteering to serve in the position. Once aboard, Tovar learned that the ship's first officer, Sub-Commander Nural was actually his adopted sister Audrey Bain, who had been sent by Section 31 because events on the Shakalak and with the Vulcans were not what they seemed. She told him that they would be saving Earth but they wouldn't be coming back. (Strategic Retreat [BG])
