There have been multiple mentions of the Unseen World across The Lord of the Rings: The Rings of Power's first two seasons. Adar (then played by Joseph Mawle) tells Galadriel in the series' first season that Sauron wanted to use the Unseen World in order to achieve a "power over flesh rather than a power of the flesh." Pre-destruction Sauron (Jack Lowden) mentions this again in the prologue of The Rings of Power's Season 2 premiere. These lines have been vague at best. In its latest episode, though, The Rings of Power finally offers viewers some insight into what the Unseen World actually is.
