What is "seefra"

Seefra is a fictional planetary system in the Andromeda universe.

Seefra-1 is considered to be the same planet as Tarn-Vedra, as discovered by Dylan Hunt in Season 5 of the show.

All characters are transported to the Seefra system at the end of Season 4, by Trance Gemini.

8 of the 9 planets in the Seefra system, save for Seefra-1, are destroyed during Season 5, as Trance Gemini's sun enters the system to become the new Seefran/Vedran sun. Not only are most planets destroyed, but the manufactured Methus suns are consumed as well. The new Vedran sun comes to a stop after consuming 8 of the 9 planets, which have been designed as an elaborate braking system.

Much of Season 5 centers on the discovery and decoding of the Methus Diagram which is a blueprint of the Methus suns, the repair of the Methus-2 sun, and the evacuation of the Seefran planets (2-9) before the approach of the new sun.
