Uldras are enigmatic fey from the frozen north. They are strange and reclusive, preferring the company of wild animals to humanoids. Uldras are wild and free-spirited, and see themselves as the protectors of the arctic; they angrily resist contact with outsiders and react violently to humanoids who disrespect the natural world. Uldras are mercurial creatures whose temperament can rapidly shift from merry laughter to savage anger to peaceful contemplation.
Even smaller than halflings, uldras rarely stand over three feet tall and weighing only 30-40 pounds. They have spindly limbs with only four digits on their hands and feet. Their skin is pale blue or snow white, while their hair is usually a darker blue or black. Uldras have a strongly elvish appearance, with pointed ears, large eyes, and otherwise delicate facial features. As they are resistant to cold, they have little use for clothing except as fashion, wearing only light furs. Uldras love hats, especially pointed ones, and take pride in showing them off.
Uldras are nomads who shun permanent settlements and even buildings, making temporary homes out of caves, hollow trees, or ice tunnels. They live in small clans of three to six family units in which all are considered equal; leadership is a temporary position assumed by the loudest or strongest individuals, and usually only lasts for a few weeks at most.
The only creatures whose company uldras enjoy are wild animals, other fey (particularly dryads), and gnomes; they consider gnomes close relatives due to their fey origin and similar temperaments. They have nothing but animosity for the despoiling orcs and goblinoids, and view dwarves and humans with suspicion at best for felling trees and mining mountains for the sake of industry.
Uldras are little-known on most of Golarion, where they are confined almost solely to the Crown of the World. They range across the frozen northern continent, where they have a peaceful but distant relationship with the native Erutaki humans and Snowcaster elves. They are found in the greatest numbers on the peninsula of Almhult, where they frequently clash with the Ulfen settlers. Uldras are found in smaller numbers in Avistan in the Lands of the Linnorm Kings and Realm of the Mammoth Lords, while rumors tell of tribes of evil uldras serving the Witch Queens of Irrisen. Uldras were once common in the ruined kingdom of Sarkoris, but since the creation of the Worldwound only a handful of demon-tainted survivors remain.
Uldras are much more common on the wandering planet Triaxus during the times when it strays further from the sun and enters its decades-long winters, ranging across the entire snow-covered world. When Triaxus moves closer to the sun and enters its long summer, however, the uldras retreat to hidden enclaves in the First World, spending years in isolation as they wait for winter to come again.
Uldra are native to the northernmost reaches of Senksen, where they fight to maintain their ancient territories against the oppressive dragon-ruled humans of that continent.
