Elves

"A smaller and lighter horse, but restive and fiery, was brought to Legolas. Arod was his name. But Legolas asked them to take off the saddle and rein. 'I need them not,' he said and lightly leaped up, and to their wonder, Arod was tame and willing beneath him, moving here and there with but a spoken word: such was the elvish way with all good beasts."

...J.R.R. Tolkien, The Two Towers

Elves are most commonly found in the forests. They are the keepers of nature; they are told to know the names of the trees and the families of animals. They are a secretive people, but can be angered when others harm the nature they are so close to. They can be fierce opponents, able to move through the trees and underbrush in silence, usually armed with a bow and arrows.
