Pre-Republic Era

The Pre-Republic Era was the earliest-known period of galactic history, and saw the formation of the galaxy itself and the propagation of lifeforms, species, and the midi-chlorians.

Legacy
"It's a biological chronology of the fall of this pre-Republic civilization." "Hmm. So your interest in this trip is in determining when exactly the galaxy fell into chaos and despair in the past."

- Ardanna Glie and Kirana Promenti

Information on planets and civilizations from this ancient era was lost in data-purges carried out by the Imperial Survey Corps and the Galactic Hyperspace Planning Council, though scholars including Ardanna Glie of the University of Bar'leth studied ancient ruins in an attempt to piece together details of former civilizations and empires. She joined Grummgar and Kirana Promenti on a quest to Rakata Prime to learn more about a fabled first Force-worshiping order.
