The Enchanted Isles consisted of a chain of islands set by the Valar in the Shadowy Seas as both a defence and cloak for Aman following the poisoning of the Two Trees and the rebellion of the Noldor. Neither the exact number of islands in the chain nor their positions were known. Few ever passed into their net, and any traveler who set foot upon the Enchanted Isles slept until the Change of the World. (The only exception to this being Eärendil and Elwing, who, by the light of the Silmaril and the permission of the Valar, escaped enchantment.) It is presumed that the Enchanted Isles went with Aman and Tol Eressëa after they were removed from the Circles of the World at the end of the Second Age.
