The Tenge are elves who have unparalleled mastery over the domain of water magic. They use this magic to allow them to live underwater on the backs of large creatures that can only be compared to giant turtles. These creatures cannot be spoken to, nor influenced in any way, but they also don't seem to react aggressively at all. Scores of Tenge mages initially raise a shield composed of air to push back the water and allow building to occur on the turtle's back, and once a stable population has been established the innate magics of all the Tenge within the shield are used to maintain it.
A symbiotic relationship between the Tenge and sea serpents known as Leviathans allow the Tenge to move through the water with ease, gaining them the title of Ithoza's traders. They move goods up and down the rivers of Ithoza, spreading information and news along the way.
