The initial Technocalypse-refugee colony died out before the arrival of the second wave of colonists at 40 Eri A-I. At first they called this tidally-locked world 'Dawn', but over time they changed the planet's name to Twilight.

The TakiCo. leaders joined the Eridanus League soon after they received the famous Charter Transmission. They became very pro-League and only a few fringe threshold bases on the planet 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.
