Mainworld Data

Mainworld Size (S)

Treece is a Meso World between 5,600km and 7,200km in diameter. The world has low gravity between 0.32G and 0.46G. The horizon will appear about 3.6km away.

Mainworld Atmosphere (A)

Treece has a pressure of 0.10 to 0.42 atmospheres. The very thin pressures require a respirator or Oxygen Mask. TL–5 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Treece has 15-25% of its surface covered by liquid water or ice. There may be a few small seas. Wilderness refueling is possible. Water for the inhabitants needs to be imported and extensively recycled. These worlds are Hell Worlds or Poor Worlds depending on their atmosphere.

Mainworld Geography and Topography

No centrally held map of the world exists within AAB Library Data records.

(Blank map, predominantly dry world.)

History & Background (Dossier)

In addition to the City of Treece, other major settlements on Treece include Witmansburg, Dishak, and Kihulam.

A significant population of Llellewyloly dwell on this world.

The poverty stricken world of Treece was most notable for its export of gallowglass troops for use by interested factions in the Imperial government, or by anyone that could afford their services. When the market for mercs imploded in the Post-Collapse period, the world subsisted upon remittances sent home by the large Treecian contingent in the military and Quarantine Service. The world gained its independence in 1162, perceiving that Inthe was stealing a good portion of this money for its own use.
