The Algoryn Prosperate is a league of independent worlds that includes Algoryn colonies as well as affiliated worlds peopled by other pan-human types.

The Algoryn are descended from root human types over many generations. They lack hair upon their heads, which are instead covered with crest-like keratinous growths. Similar nodules of keratin form a thick scaly layer upon their exposed flesh. This dense protective layer shields the Algoryn against the harsh rays of the twin suns of Algorya, which periodically bathe the planet in dangerous levels of heat and radiation.
