were called Valar; the lesser Ainur were called Maiar. Ages of Arda Spring of Arda When the Valar entered Arda, it was still lifeless and had no distinct geographical features. The initial shape of Arda, chosen by the Valar, was much more symmetrical, including the central continent of Middle-earth. Middle-earth was also originally much larger, and was lit by the misty light that veiled the barren ground. The Valar concentrated this light in two large lamps, called Illuin and Ormal. The Vala Aulë forged two great pillar-like mountains, Helcar in the north and Ringil in the south. Illuin was set upon Helcar and Ormal upon Ringil. In the middle, where the light of the lamps mingled, the Valar dwelt at the island of Almaren upon the Great Lake. This period, known as the Spring of Arda, was a time when the Valar had ordered the World as they wished and rested upon Almaren, and Melkor lurked beyond the Walls of Night. During this time animals first appeared, and forests started to grow. The Spring of Arda was interrupted when Melkor returned to Arda, creating his fortress of Utumno or Udûn beneath the Iron Mountains in the far north. The period ended when Melkor assaulted and destroyed the Lamps of the Valar. Arda was again darkened, and the fall of the great Lamps spoiled the symmetry of Arda's surface. New continents were created: Aman in the West, Middle-earth proper in the middle, the uninhabited lands (later called the Land of the Sun) in the East. At the site of the northern lamp was later the inland Sea of Helcar, of which Cuiviénen was a bay. At the site of the southern lamp was later the Sea of Ringil. After the destruction of the Two Lamps the Years of the Lamps ended and the Years of the Trees began. Years of the Trees After the destruction of the Two Lamps and the kingdom of Almaren, the Valar abandoned Middle-earth, moving to the continent of Aman. There they built their Second Kingdom, Valinor. Yavanna made the Two Trees, named Telperion (the silver tree) and Laurelin (the golden tree) in the land of Valinor. The Trees illuminated Valinor, leaving Middle-earth in darkness. The Years of the Trees were contemporary with Middle-earth's Sleep of Yavanna (recalled by Treebeard as the Great Darkness). The Years of the Trees were divided into two epochs. The first ten
