Hubirus is a barren world with no overt population, government, or law level.

• This world could be populated if anyone had an inclination to do so...
• It is an unclaimed Non-Aligned world located in the Ykoroni Subsector of Iphigenaia Sector.

• This world is a "Twilight Zone World", a planet that is tidally-locked to its star. It has a hot side that permanently faces the star, a cold side that permanently faces away, and a narrow twilight zone in-between.

Description (Astrography & Planetology)

The system is a binary, made up of two relatively close stars.

• The two stars orbit a barycenter once every few weeks.
• The worlds that make up the system follow near-Bodean circumbinary orbits around the pair.
