On a planet far from our own, there is no land above a endless sea, and oxygen is so rich that even humans can breathe water. Much like the legend of Atlantis, cities line the sea floor, sleek and bright.
Three tiers divide the waters - the light-filled Lumin Zone, the dim Drift Zone, and the pitch black Abyss below.
For generations, the Deepseas, beings born from the Abyss where humans cannot go, have lived alongside humanity as allies and friends, but as the borders are starting to close, and they may not longer be safe in the light.
