This triple system near Sol is known variously as Keid, Omicron2 Eridani or 40 Eridani. The first wave of colonists were refugees from the Technocalypse who arrived in 789 AT in arkships built by GAIA. Most colonists settled on Twilight, but a smaller fraction established colonies on Umbra and Orson, and in the L2 Lagrange point of Dawn.

The colonies joined the Eridanus League soon after they received the famous Charter Transmission.

The original colonists were joined by a fleet organised by TakiCorb which arrived in 1100 AT. The Keid colony became very pro-League and only a few fringe threshold bases in the outer system dissented from continued League membership. Etodist, Mondecumen, and FalunDafa missionaries were not as successful here as on other League worlds due to the prevalence of animist beliefs.

Twilight, which already had a limited xenoecology when discovered, became an important Inner Sphere world after the fall of the Eridanus League. See also the separate article on Twilight here.
