As explained in The nature of spirits and the fey, the fey are collective entities comprised of many (dozens to millions) of kami, all bound together by a common obsession with some aspect of mortal life. The sages of the Western Empire divided them into four groupings named after the seasons; if this distinction has meaning for the fey themselves, they're not saying. But they acknowledge the distinctions and do not take offense when such terms are used. Which, I guess, is good enough for this poor student of such beings.

This document attempts to elucidate some of the distinctions between the types of fey, as well as noting some of the social structuring that seems to exist among them. Your guide, the humble Walker, bids you welcome to the strange world of the fey.

Who are the shadowy forces behind the endless tide of frozen invaders from the Nocthian Caldera? Why do they hate the dragonborn of The Remnant Dynasty so much?

When the First Wish broke the titan's runic reign and caused them to degenerate, two major peoples resulted from choices made. The dwarves are the more common (at least in Noefra) of the two; the giant kindred are the others. The name the learned use for the giant kindred is the Jazuu, the Written People. While most people in the Federated Nations believe that the Jazuu belong to multiple races, the truth is more complicated.

At the end of the First Age, when Titan and Wyrm rose to domination, not all aelvar resigned themselves to the yoke of bondage. Some fled through natural gaps in the veil surrounding the Mortal Plane and approached the Center of Worlds in the Astral, begging for admission and refuge. The exact request and the response of the Great Mechanism and its guardians is unrecorded, but Cysgor lore contains the following fragment:

Dwarven culture is entirely clan-oriented. The clans are both family and government, although multiple clans may live in one city.
