Kepzyr
Kepzyr was the home planet of the Kepzrs.
The ancient Kepzyrs built temples on the planet in the 29th century.
By the 39th century, heavy deforestation was carried out on Kepzyr.
In the 49th century, Kepzyr was savage and underdeveloped. It was the location of the Unheard Treasure of Kep-ili-Koo.
In the 109th century the planet was supposed to be a thriving mid-level civilisation. The actions of Frank Reade Jr turned it into a wasteland by this time. There were no mountains or valleys, no oceans or continents. The only thing in the atmosphere was slight traces of nitroglycerin, dating back sixty centuries.
