The only class M world in the Cygnus system, Qo'nos is the homeworld of the Klingon Empire and the seat of its capital, veng wa'DIch. Possessing a single landmass bordered on all sides by an extremely salty sea, the planet is roughly one and a half times the size of Earth, experiencing a vast range of hostile climates, from lush tropical forests, to arid volcanic wastelands, to sub-freezing glacial plains. A swirling cover of storm clouds is nearly omnipresent over the world, yet another effect of the ecological turmoil thanks in part to a passing asteroid which caused a shift in the planet's axis.

Other cities of note on Qo'noS are Vospeg, the planet's primary industrial center, Quin'let, home of many of the Empire's noble Houses, and Qam-Chee, site of one of the greatest moments in the chronicles of Kahless the Unforgettable and home to the Empire's premiere military academy.
