Andromeda

The Heart of the Journey (1) (5x21)

:

Dylan and his crew deal with the survivors on Seefra One promising them that it will soon become like Tarn-Vedra once was. Harper works on getting the "low-tech" mechanism inside the planet to work properly, while Trance explores her new powers resulting from the re-establishment of her sun. She introduces Dylan to the group that her impersonator worked for, "the Nebula," a group of stars controlling all the galaxies, also an enemy of the Abyss.
