Qo'noS

From Tardis Wiki, the free Doctor Who reference

In a parallel universe, the planet Qo'noS was the homeworld of the Klingons. Its First City was the capital of the Klingon Empire.

In a possible future shown to Captain Jean-Luc Picard by the Eleventh Doctor, the population of Qo'noS was converted by the Cybermen. (COMIC: Assimilation²)
