The continent of Akavir, also known as "Dragon Land", is a landmass east of Tamriel. The two continents have a history of animosity towards each other, with Akavir invading Tamriel several times in the past and Tamriel invading Akavir at least once.
There are four major nations within Akavir:
When they are not trying to invade Tamriel, they are fighting each other.
“Akavir is the kingdom of the beasts. No Men or Mer live in Akavir, though Men once did. These Men, however, were eaten long ago by the vampiric Serpent Folk of Tsaesci. Had they not been eaten, these Men would have eventually migrated to Tamriel. The Nords left Atmora for Tamriel. Before them, the Elves had abandoned Aldmeris for Tamriel. The Redguards destroyed Yokuda so they could make their journey. All Men and Mer know Tamriel is the nexus of creation, where the Last War will happen, where the Gods unmade Lorkhan and left their Adamantine Tower of secrets. Who knows what the Akaviri think of Tamriel, but ask yourself: why have they tried to invade it three times or more?
