Jekyll has both an unbreathable thin atmosphere and a lack of surface water making habitation by sophonts difficult. The system has a population between 10,000 and 10 million, lacking the industrial base to be completely self-supporting. This is a high technology world with available technology over the standards for Charted Space. It is a member of Third Imperium in the Ushra Subsector of Dagudashaag Sector and in the Domain of Vland. Jekyll, as a member world of the Third Imperium, holds the estate of an Imperial knight, a member of the Imperial Nobility charged with overseeing the world. During the Long Night this world was named Gipu Irim.

Astrography and planetology[edit]

Jekyll is a member of the Dagudashaag Main.

The name is taken from an ancient Terran novel Dr. Jekyll and Mr.Hyde, given by the Solomani who settled on this world. It is a story of a doctor who uses drugs to change his personality to open up and release his darker side. The analogy was drawn when the settlers first experienced the wildly fluctuating climate. At the equator the summer temperature switches from 65ºC to -11ºC between day and night. At the same latitude the temperature changes between 65ºC and -64ºC from summer to winter. There are more extreme fluctuations at higher latitudes. This has kept colonization to a minimum, but the world is well served with a class A starport as Jekyll is an important transport nexus within the subsector.

History and background[edit]

Jekyll only has one city, an underground settlement connected to the surface starport by multiple grav-tube elevators. The city is called Hyde after Jekyll's dark aspect. Although extremely warm and comfortable due to tapping the planetary magma, the city has no natural light and its access tunnels are poorly lighted creating an extremely gloomy atmosphere.
