N'Vak colony

The N'Vak colony was a Klingon colony in the 2150s.

In 2154, N'Vak was one of the first colonies outside the Qu'Vat colony to be struck by the Qu'Vat virus. The Klingon High Council ordered the destruction of the world after it was infected. 

In 2156, told Captain Jonathan Archer that part of the reason the High Council refused to help Earth in the Earth-Romulan War was the spread of the virus beyond N'Vak.
