The Eaür were one of the precursor races that gave rise to the Endless.
Eaür society, though sedentary and communal, was ever at risk from the large numbers of predators that stalked the oceans.
For this reason the Eaür were the first to aggressively adopt and integrate other species into their society. Using them to serve their needs in their industries.
The Eaür were a race of sedentary hunter/gatherers, these ocean dwellers evolved from many-armed sea creatures, growing and tending the great purple coral reefs that provided both food and shelter.
