The Pathfinder Chronicles Gazetteer contains all the common races you're used to—dwarves, elves, gnomes, halflings, the half-breeds, and humans. It also contains, however, numerous human ethnicities that exist across the Inner Sea region of Golarion. Among the most numerous of these ethnicities are the Chelaxians, a group descended from the ancient Azlanti themselves. The following quote appears in the Pathfinder Chronicles Gazetteer, in a sidebar dedicated to this elegant and haughty ethnicity.
"The distant, bastard descendants of Azlanti refugees spread throughout southern Avistan as if entitled to the land by the gods themselves. Sharp-featured with dark hair, dark eyes, and pale skin, Chelaxians differ from their duskier Taldan cousins due to widespread intermixing with pale-skinned Ulfen raider-merchants in the distant past (from whom they also gained the legendary Chelaxian wrath).
"Chelaxians are best known for their pride and ambition, possessing a sense of entitlement that has followed them through history. They tend to sneer upon savagery and respect strong authority. Quick to be offended and slow to forgive, Chelaxians hold grudges longer than most other humans. They are most common in the current and former holdings of the once-vast Empire of Cheliax, including Andoran, Galt, Nirmathas, Molthune, and the southern reaches of Varisia. Most speak Taldane."
