Nogo (Gliese IV) is the fourth planet from the sun of the Gliese system, Banu Protectorate. A lush, temperate planet with an oxygen-nitrogen atmosphere and a variety of climates, it is nonetheless avoided by the Banu. It is unclear why Banu refuse to live there, especially in light of ample evidence that they lived there in the past.
After a long analysis period that determined that the planet was safe, Humans constructed multiple colonies and have lived there ever since. Agricultural exports to the nearby Lyris flotilla make up the bulk of Nogo's economy.
