On Chysyl, a moon orbiting the gas giant of Peridor in Jaern's star system, there exists a world filled with many creatures much more intelligent than anyone expected. About ~30 years ago a psionic burst granted the avian races of the moon sentient life, and since then they've built up a civilization with each other.

The avians of Chysyl can be most easily split into four categories, Eufalconi, Sphenecine, Akvo'avians, and Verraerians (though hybrids of these do exist as well as many subspecies.

Eufalconi often take the roles of rangers, peacekeepers, and soldiers for society, due to their superior aerial mobility and history as hutners.

Sphenecine are amongst the more long-lived of the avian races. Their innate psionic powers sometimes gets them heralded as great ones, but other times causes them to get shunned as strange magic holders.

Akvo'avians, most often found at the poles of Chysyl, are known for their active expansion war campaigns, trying to win at all costs. They are also fond of tourists.

Verraerians often run the tree-top cities as they were the first to start establishing governments and laws.
