Okay after watching a video about the Lore of Tamriel and Mundas, this bothers me... Those are the moons that orbit Nirn, the planet with 5 continents on it. Tamriel (Skyrim, Cyrodil Hammerfell... etc) Akavir, The continent where dragons come from is to the east of Tamriel and has had conflicts with the continent many times. Akavir has invaded Tamriel many times in the past and Tamriel has invaded Akavir at least once. The continent, Atmora, is the landmass North of Tamriel. And legend says that it was from here that humans first came. Ysgamor fled cival war in Atmora, determined to make a new life for his people in Tamriel. The ancient Island Yokuda... you know what... Screw it here's a link to the video I got this from. They deserve the credit.
