The governance of this world is from Inthe (Spinward Marches 2410). It is a member of Third Imperium in the Lanth Subsector of Spinward Marches Sector and in the Domain of Deneb. Treece, as a member world of the Third Imperium, holds the estate of an Imperial knight and the fiefdom of a viscount. Both are members of the Imperial Nobility charged with overseeing the 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.
