Qo'noS

From FEInfobase

Qo'noS was the homeworld of the Klingon people. It was also the capital world of the Klingon Empire. Contact was lost with the planet in 2388 during the the Borg War.

In 2403, the planet was re-explored by a Klingon Task Force in conjunction with the USS Enterprise F. They found a desolate world infested with Borg nanites but with no Borg population. It was determined that large scale atmospheric reprocessing would be able to purge the nanites and create a world suitable to re-populate. Given the importance of the planet to the Klingon people and for further re-development of the Alpha Quadrant, it was determined to be a worthwhile effort for resource allocation. The planet is undergoing heavy atmospheric modification at this time with several dozen large processors anchored in orbit.
