Group of star systems located in the region of space once containing the Tion Hegemony. The area was largely devoid of human life at the time of the founding of the Republic. Various corporate interests negotated for ownership of many of these systems. Long home to a largely corpro-capitalist population, it came as no shock when these systems declared their independence from the Republic.

The present head of state of the Tion Principality is Davrosh. Once a part of the New Sith Empire, the Tion Principality broke away after the death of Bellisarius. Presently one of at least three major powers (others being the Jedi Order and New Sith Empire) struggling for dominance while loosely allied against the Dark Swarm.
