Gallifrey (Regenerators' timeline)

On one Gallifrey, Rassilon failed to complete the Eye of Harmony. This was because he trapped the Krilig. Romana II, Narvin and Leela were trapped there after stopping the Krilig from escaping. (AUDIO: Forever)

After these events, the slaves were released and settled on a Zeiton-7 field which the mining guild wanted to mine. (AUDIO: Emanciptaion) There were plenty of scientific research facilities scattered along the outlands, one of which was where Hector's Time Experiments were held. (AUDIO: Evolution)
