The Daoine-Speir are a race of winged reptilian humanoids who had been all but forgotten by the world above prior to their involvement in the Ascention of Treth. There are still those who would balk at a proper description of them, but those who have encountered their army know better than to scoff.
With pale skin and wings that have long atrophied due to lack of use, the Daoine bear the scars of generations of exile having been driven underground millennia ago by an elven campaign of extermination. They are a generally tall and thin race with a strongly muscled barrel chest, a face reminiscent of dragons, a short tail, and backward bending legs with large, strong feet.
While much of the Daoine forces are now traveling with the human city of Treth in their efforts to topple the Infinite Empire, there is at least one splinter group who remains in opposition to that action and preferred to not get involved.
