The Po'Tun and Tsaesci were both greatly weakened by the war and became archenemies.
The ensuing war wiped out all the Dragons of Akavir, with all survivors fleeing to Tamriel.
The Red Dragons were enslaved and the Black Dragons fled, some of them seeking sanctuary with the Po'Tun, a race of tiger people native to Akavir but likely related to the Khajiit. When the invaders were fought off, the surviving Akaviri in Tamriel were granted amnesty, and some of them pledged themselves to the Dragonborn Emperor Reman I, becoming the ancestors of the Blades.Īkavir was the original home of the dragons, but the Tsaesci attempted to 'consume' them after the Akaviri.
The Akaviri are now thought extinct in Akavir, but a force of them traveled to Tamriel with their Tsaesci masters when they invaded Tamriel. They were enslaved, and eventually 'eaten' (possibly literally) by the snake-like Tsaesci, also natives of Akavir. The Akaviri are - or were - a race of men native to the continent of Akavir. Also, they did not return to Akavir because they are not from Akavir.
