History & Background (Dossier)[edit]

World Starport (Sp)[edit]

Taproban has a Class B Starport, a good 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 most kinds of repair, and construction of non-starships. Most ports of this classification have both a Highport and a Downport.

World Population (P)[edit]

World Demographics[edit]

Humaniti, population 100%

World Government (G)[edit]

Taproban is governed by a Civil Service Bureaucracy. The leadership of the government is another form (democracy, dictatorship, oligarchy), but the bureaucracy leadership influences policy. The government leadership may select the bureaucracy leadership, but not its membership. Usually the governmental leadership is divided, or incapable of setting policy and the bureaucracy provides a stabilizing influence. The bureaucracy may be the full government bureaucracy or a section with limited jurisdiction but considerable influence like the military.

World Law Level (L)[edit]

Taproban has a moderate law level with laws covering many areas of government and interaction. These laws are simple enough that most people can act as their own advocate, though for serious issues a professional is recommended. Law enforcement officials will be present, but not in great numbers. All firearms, and anything more destructive, are typically regulated or prohibited.

World Technology Level (TL)[edit]

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

World Military[edit]

In 1105, Taproban was both the host to half the 61st Fleet, and sponsored its own colonial squadrons[2]:

  • 1st Taproban Assault Squadron
  • 2nd Taproban Assault Squadron
  • 1st Taproban Scout Squadron
  • 2nd Taproban Scout Squadron
  • 1st Taproban System Defence Squadron
  • 2nd Taproban System Defence Squadron
  • <Unnamed> Mercenary Squadron
  • <Unnamed> Mercenary Squadron

and had issued some 24 Letters of Marque

World Economy[edit]

No information yet available.

Trade Data[edit]

Taproban had a significant trade surplus mainly because it is on a minor trade route running from Atsah Subsector into Vargr territory[3].


The habitations of Taproban have historically been constructed to be defensible because of the continued low levels of Vargr buccaneering that have occurred over the centuries of its settlement. They were not generally sufficiently large as to make tempting targets for massive strikes while being large enough for collective defence.

As much as 10% of the population (Just under one million people) were based in orbit at the planet's peak occupation.

World Infrastructure[edit]

This world possesses TBD infrastructure.

World Culture[edit]

No information yet available.

World Language/s[edit]

Because of the proximity of the Vargr Extents, Aekhu is also spoken by starport officials
Taproban's local patois of Anglic includes a number of words that can be traced back to an ancient, and otherwise extinct language called "Tamil", and a large smattering of Vilani loan words.

Imperial Landed Nobility (N)[edit]

Taproban, as a member world of the Third Imperium, holds the estates of two members of the Imperial Nobility, who are charged with overseeing the world.

Taproban is the fief of the Marquis of Million[4].

World Timeline[edit]


Taproban was unsettled in pre-Imperial times


Taproban troops played a key role in the Civil War (600-629)/Second Frontier War (615-620) when they successfully fought to stabilise the border against Vargr incursions[5].

For centuries Taproban formed a triumvirate of power in Million Subsector with Fel (Deneb 2904) and Aerfor (Deneb 3104)), drawing on support from, and supporting both the Duchies of Atsah and Antra at various times[6].


Taproban was completely deserted by 1136 as part of the Abandonment.
