Star Trek Expanded Universe

The CUW Prenkar was a Galor-class cruiser that served during the 24th century. (Star Trek: Sigils and Unions)

The Prenkar, commanded by Gul Igrun, was one of the three warships in the vicinity of Septimus III when the Klingon fleet attacked. The Prenkar, Sherouk, and Romac immediately came under a withering Klingon assault and before either of Igrun's fellow guls could intervene, the ship broke up and the pieces were incinerated on re-entry into the planet's atmosphere.

Septimus Massacre survivor Tayben Berat would be deeply haunted by his inability to save the Prenkar, and this loss, along with that of the Eleventh Order, would solidify his decision to enter into open rebellion against the Dominion. (Star Trek: Sigils and Unions: The Thirteenth Order)
