Morrowind. Dagoth Ur would bring about a paradise reality where everyone is shown how to wake from their slumber, and are endowed with something greater than the powers of all the gods, which will bring the ends of all suffering, sorrow, pain, hate, and jealousy.
He would unite all life to a frightening and beautiful singular purpose: a utopian reality would be created, where all life is sacred, and nothing is taken for granted; it would look alien, monstrous and strange, but that is the ultimate cost of profound and terrifying change.
Yeah and Yog Sothoth(known in the Elder Scrolls as herma mora) will free you from the prison of time. All it will cost you is everything that makes you exist.
Wait, Hermaeus Mora is canonically Yogg Soth-oth? Are Cthulhu or Nyarlathotep represented anywhere in the Elder Scrolls series?
