The Silvan Elves were descendants of the Nandor (and thus in origin Teleri), who had lingered in the Anduin Vales during the Great Journey of the Eldar in the Elder Days. The Silvan Elves hid themselves in their woodland realms beyond the Misty Mountains and became a scattered folk hardly distinguishable from Avari. While some of the Nandor continued to Eriador and later entered Ossiriand, some remained in the Vales of Anduin, and from these latter originated the Wood-elves.
