Harlequin has both an unbreathably 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. It is a member of Third Imperium in the Sapphyre Subsector of Dagudashaag Sector and in the Domain of Vland. Harlequin, as a member world of the Third Imperium, holds the estate of an Imperial knight, a member of the Imperial Landed Nobility who acts as an Imperial representative to the world. During the Long Night this world was named Leka Id.

Astrography and Planetology

Harlequin is a member of the Dagudashaag Main.

System Data

A remarkable double planet system, Harlequin and its twin Pierrot (H2A6103-9) orbit a bloated star in the final stages of evolution. The star, Gastoyne, has reached the stage where it has started to blow off its outer layer and a steady wind of carbon soot is being blown out of the system. Over the millennia this carbon dust has settled on the outward facing hemispheres of Harlequin and Pierrot. The pair are tidally-locked, giving both worlds a characteristic black-and-white appearance.

History and Background

In 827, the Bolivaran petrochemical corporation Stahimeyer-Ramires SA conducted a detailed survey of the system and found that the complex organic oceans on Pierrot included a significant percentage of buckminserfullerenes and lanthanum-doped nanotubes (a naturally occurring superconductor). Randolph Stahimeyer immediately authorized the purchase of much of Harlequin/Pierrot, and the construction of a plant to exploit Pierrot's petrochemical resources.

Construction began on a beanstalk system connecting the two worlds, designed to pump raw nanotubes to refining centers on Harlequin. In these plants they would be turned into lanthum carbosilicate wires used in starship jump grids.

Construction of the 'Worldbridge' began in 836 at the midpoint of the Harlequin/Pierrot system, the shaft of the Skyhook extending slowly toward the surfaces of both planets. Despite technical problems and labor disputes which greatly increased the cost of the project, work proceed until 841 when the ends of the Worldbridge were barely a thousand kilometers above the surfaces of the worlds.

Stahimeyer-Ramires, its financial resources so depleted by the Worldbridge project, was the victim of a hostile takeover by Interstellar Petrochemical Processing (IPP). IPP replaced Sashimeyer's senior management, took over the most profitable refining plants in Pact and Bolivar, and sold the rest. The subcontractors on the Worldbridge went bankrupt and the project was abandoned barely a step from completion.

Three centuries later the Worldbridge has become Randolph's Folly, an interplanetary derelict. Forty thousand kilometers of spun monocrystalline plasteel tubing has attracted a great many salvagers and wildcat scrap merchants. Incompetent attempts to dismantle the structure have left parts of it critically unstable. In 1102, two hundred kilometers of skyhook cabling broke free and fell onto the surface of Harlequin, damaging several habitats. The people of Harlequin have appealed to the Imperial Navy to make the structure safe but no official moves have been made.

World Starport (Sp)

Harlequin has a Class C Starport, an average quality installation which features amenities including unrefined fuel for starships, some brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing maintenance and other kinds of repair. Ports of this classification generally have only a downport, unless this is a trade port or system with an hostile environment mainworld.
