The following is a list of planets in the area of space formerly known as the Delphic Expanse. The perimeter of "the Expanse" was made of dangerous thermobaric clouds making it difficult for ships to enter or exit the area, but the clouds were dissolved in 2154 and the area returned to normal space.
