Daled IV

A planet inhabited by two factions of allasomorphs divided by civil war throughout their recorded history. The planet was locked in synchronous rotation—one rotation for each revolution around the Daled star—and the resultant all-night/all-day hemispheric split gave rise to the two disparate cultures. A child, Salia, was born of parents from both sides and spirited away soon after their deaths so she could be raised in safe seclusion and return at age 16 in hopes of bringing peace to the planet. The world had no formal contact with the Federation, but Starfleet ships served as Salia’s courier both ways. Daled IV also had at least three moons, the third an inhabited Class-D world.^[1]
