History & Background (Dossier)

World Starport (St)

Halcyon has a Class A Starport, an excellent quality installation which includes all the expected amenities including refined fuel for starships, brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing annual maintenance, overhauls and other kinds of repair, and construction of both starships and non-starships. Most ports of this classification have both a Highport and a Downport.

World Population (P)

Halcyon has population of 800 sophonts (hundreds).

• This is a Low Population World and the population would be too low to sustain itself without moderate outside assistance. This may represent a large transient population such as the crew of a fleet of starships, the dwindling remnants of a dying colony, a construction team building a new colony, or an outpost that could evolve into a colony.

World Technology Level (T)

Halcyon possesses a Technology Level of TL–11 or TL-B in Hexadecimal Notation.

• Common Communication technologies for this TL include: Holovision, Personal Global Communications, and advanced Translators.
• Common Power Generation technologies for this TL include: Increasingly advanced fusion plants and advanced fuel cells.
• Common Transportation technologies for this TL include:
  • Land, Water & Air: Personal G-Tubes and advanced gravcraft.
  • Space: Advanced interplanetary spacecraft (System Craft).
  • FTL: Jump Drive-2.

World Government (G)

Halcyon is governed by a Corporate Polity, having a single corporation with a typical corporate structure as a government. Essentially, this is a "company town" (or world). The typical corporate-run world usually has a single purpose. Examples include mining, agriculture, or other kinds of resource extraction. But rather than a simple base of operations, there are facilities for housing workers and their families, including hospitals, schools, and other infrastructure. How, or if, the children of the workers are incorporated into the workforce varies with companies. The corporation running the world may be a subsidiary of a larger interstellar corporation.

World Law (L)

Halcyon has no law in practice. It is an Anarchy. On many worlds, this by itself justifies an Amber Zone advisory. There are few laws, covering only important areas. There may be few or no law enforcement officers, the expectation is citizens will bring law breakers to the attention of the Judicial system. Legal proceedings will be fast, with few people involved. For interactions outside of the framework of the laws, cultural norms dominate.

• It holds the estate of an Imperial knight.
