History & Background (Dossier)

Heroni is a Puzzle World and is designated as an Amber Zone. It presents particular risks and dangers due to the environment or native life forms, laws or customs, or other conditions that are not well understood.

• Visitors are advised to act with caution.

Heroni is ruled by a king, who also controls the Royal Mercantile Navy of Heroni — a fleet of small freighters operating on several steady-profit routes in the surrounding subsectors. Heroni is heavily industrialized and Heroni goods find markets on lower-tech worlds throughout the subsector and beyond.

World Starport (St)

Heroni 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)

Heroni has a population of 7,000,000,000 sophonts (billions).

World Government (G)

Heroni is governed by a Non-charismatic Dictatorship. This is a continuation of the charismatic dictatorship, where the original leadership has died or retired and been replaced by allies or protégés. The justifications for the original change in government remain as well as the assertion of rights to rule.

World Law (L)

Heroni has a high law level with laws covering many areas of interactions of people, corporations, and the government. A few worlds with this law level may be Amber Zones. Any interaction with the judicial system requires an Advocate trained in the local legal system. Law enforcement is present almost everywhere, either as people or via technology. Legal proceedings can take weeks to months to resolve and involve a dozen or more people. All objects specifically manufactured as weapons are typically regulated or prohibited (outside private residences or visiting starships).
