Zai-5 is the only real planet in the Zaibon System.
Standard Gravity (1G). Thin, tainted atmosphere. Frigid Cold. No surface water.
The mining operation, good quality spaceport, and domed settlement were once the private fief of Baronet Illestair Praukun, but the Baronet left the planet in Doctor Roguhu’s care when he left to join in the Fifth Frontier War. He has neither returned nor been heard from since.
In the Baronet’s absence, the Baron Dr. Roguhu has taken to using the gothic style Great Hall on Zai-5 as the site of his annual Holiday Parties.
