We do know that there are/were humans from Akavir, to the Tamrielians they were initially known as the Akaviri before they learned of the existence of different races from Akavir. After that they started to call the Akaviri humans the Tsaesci(As all the races from Akavir are called by the name of their nation). All the Akaviri Invasion of Tamriel were by the Tsaesci. The Invasion of Akavir by the Empire was also in Tsaesci(The nation) and they encountered the humans. The confusion is because some books call the Tsaesci serpent-men. In Tsaesci it has some of the theories. All the theories include humans in the Tsaesci. The Theories are:
 * The Tsaesci are entirely human.
 * The Tsaesci are entirely snakes, but have enslaved the humans(Akaviri) on their continent (instead of eating them) and use the humans to make up the bulk of their armies. As political savants, the Tsaesci were wise enough to limit their direct interaction with humans from other lands to only high-ranking nobles of both races. In this case, both the snake people and their human slaves would be considered Tsaesci, with the humans being able to blend in with Imperial society. Since the invading armies of the Tsaesci were more often referred to as "Akaviri" instead of "Tsaesci", it would seem the invasions mainly consisted of human Akaviri footsoldiers, with the Tsaesci only being present as high-ranking officers. This also puts a slightly different spin on the "amnesty" granted by Reman I -- it may have been more of an asylum for the human slaves against their Tsaesci masters.
 * The final theory is that there were two races of beings, one human and one snake-like. It is worth noting that the humans are never directly referred to as "Tsaesci" but usually as "Akaviri". This supports the idea of two different races. During the two invasions the human Akaviri still lived but sometime after the Empire's failed invasion they were wiped out by the snake-men, the Tsaesci. Thus today there are no more humans on Akavir.
