Guerra de la Cólera
In the extreme north-east, beyond the Pelóri, was the Helcaraxë, a vast ice sheet that joined the two continents of Aman and Middle-earth before the War of Wrath. To prevent anyone from reaching the main part of Valinor's east coast by sea, the Valar created the Shadowy Seas, and within these seas they set a long chain of islands called the Enchanted Isles or Magic Isles.
