Hermaeus Mora is the Daedric prince whose sphere is the scrying of the tides of Fate, of the past and future as read in the stars and heavens, and in whose dominion are the treasures of knowledge and memory. His name is also spelled Hoermius Mora, Hormaius Mora, or Herma-Mora. Also called the Demon of Knowledge, he is vaguely related to the cult origins of the Morag Tong if only by association with his sibling, Mephala. Unlike most princes, Hermaeus Mora does not take on a humanoid form at all, living instead as a grotesque green mass of tentacles and claws.
In Skyrim, Hermaeus Mora is encountered during the travels of the Dragonborn on a quest for the College of Winterhold, where they met a champion of Hermaeus Mora, Septimus Signus. In the Discerning the Transmundane quest, Septimus requests that the Dragonborn bring him a sample of the blood of each of the elven races, in order to recreate the equivalent of Dwemer blood and thereby unlock the Dwemer lockbox upon which he was working. Hermaeus Mora then confronts the Dragonborn directly, saying that if they fulfill Septimus’s request, they would take his place as the daedra’s champion, and be well-rewarded. The knowledge of the Oghma Infinium is given as a reward.
