Civilizations

900,000: Chodak Empire collapses. T'kon Empire begins in Kridnar - possibly Age of Cimi.^[1]
800–700,000: Possible origin of Z'Tarnis Nebula. The T'kon leave for unknown reason.^[1]
700–600,000: Udurioch and Orjoto civilizations emerge in Kridnar. They eventually fight to mutual destruction. T'kon visits - Age of Makto.^[1]
600–500,000: T'kon Empire collapses. Kridnar is visited by an unidentified possibly proto-Vulcan race.^[1]
500–400,000: Widespread destruction in Kridnar by left-over Udurioch/Orjoto weapons, a problem that would persist until at least the 24th century.^[1]
500,000 years ago to 100,000 years ago: The Forerunner Era was characterised by almost complete ignorance on the civilisations of the time. Knowledge was limited to a few scraps, while archaeology crossed over with paleoanthropology and geology. The best known civilisations were the Arret, the Fett and the Bursen.^[2]
Over 500,000 years ago: There was reliable evidence for interstellar travel dating back over 500,000 years, in the form of identical artifacts found on different planets, suggested it was already old and commonplace. The largest source for this evidence was in the Rigel system, containing fragments of most of the ancient cultures of the time, who all traded and fought through the worlds of Rigel.^[2]
400–300,000: Possible Iconian visits in Kridnar.^[1]
300–100,000: Iconian civilization collapses.^[1]^[3]
100,000 years ago to 40,000 years ago: The Emergent Era was better known to archaeologists and historians of the 23rd century. Three civilisations were dominant at this time: the Ena, the djKen and the Querat, though separated by three great Interregnums, marked by primitivism and a lack of interstellar space travel.^[2]
100,000 to now: Miscellaneous unclassified traces in Kridnar.^[1]
38,000 BC to 18,000 BC: The Preserver Era, in which the Preservers were active.^[2]
