Tharrill is a rich, agricultural garden world with a near-ideal, utopian environment conducive to most sophonts.

Description (Astrography & Planetology)[edit]

Remarks: Tharrill is a pleasant agricultural world with a fairly unremarkable history.

  • Settled from the Carrillian Assembly shortly after that state's formation, the colony never joined, preferring to remain a quiet, independent backwater world.
  • This system is part of the Grendal Group.
