THE PLANE OF QOQ is unusual in having two rational, or more or less rational, species.
The Daqo are stocky, greenish-tan-colored humanoids. The Aq are taller and a little greener than the Daqo. The two species, though diverged from a common simioid ancestor, cannot interbreed.
Something over four thousand years ago the Daqo had what the Planar Encyclopedia refers to as an EEPT: a period of explosive expansion of population and technology.
Before it, the two species had seldom come in contact. The Aq inhabited the southern continent, the Daqo were in the northern hemisphere. The Daqo population escalated, spreading out over the three landmasses of the northern hemisphere and then to the south. As they conquered their world, they incidentally conquered the Aq.
