Menti Celesti

The Menti Celesti were a group of deities which the ancient Gallifreyans worshipped during the Pythia's rule. They were made up of the leading Eternals, including Pain, Time, Death, (PROSE: Cat's Cradle: Time's Crucible) Life, and Fate. (PROSE: Hark! The Herald Angels Sing)

Death once explained to Timothy Dean that she and her many sisters were the dreams of Time Lords, leaking across the universe and occasionally given form by beings such as the Timewyrm. She also mentioned that they appeared to some Time Lords in nightmares or near-death experiences and made deals, sometimes even making the Time Lord their Champion. (PROSE: Human Nature)

Prior to the War in Heaven, all the goddesses save Death fled the Spiral Politic in their six-folded home. (PROSE: Hark! The Herald Angels Sing)

Behind the scenes
Mags L. Halliday's A Handful of Silver from the 1999 charity anthology Perfect Timing 2 asserts there is another Gallifreyan Goddess named Fate. Chris McKeon's unlicensed 2008 completion of Craig Hinton's Time's Champion introduced Life, Hope, and Disciple.
