The Bosmer are the various barbarian Elven clan-folk of the Western Valenwood forests. In the Empire, they are collectively referred to as "Wood Elves," but "Bosmer", or "the Tree-Sap People", is what they call themselves. "Tree-Sap" suggests the wild vitality and youthful energy of Wood Elves, in contrast with their more dour cousins, the Altmer and Dunmer. Bosmer reject the stiff, formal traditions of Aldmeri high culture, preferring a romantic, simple existence in harmony with the land, its wild beauty and wild creatures. These country cousins of the High Elves and Dark Elves are nimble and quick in body and wit, and because of their curious natures and natural agility, Bosmer are especially suitable as scouts, and thieves. But most of all, the Bosmer are known for their skills with bows; there are no finer archers in all of Tamriel. Their ability to command simple-minded creatures is also well known. They are also religiously carnivorous and cannibalistic, but do not destroy trees or plant life, though they are not averse to using wooden or plant-derived products created by others.
The Elves of Valenwood have always been involved in political arguments between the other races of Tamriel, but have never waged war with other nations, only defended their lands countless times, from the Khajiits of Elsweyr and the High Elves of the Summerset Isle.
They have never been truly allied with other nations because of mistrust and their own beliefs and traditions.
