Arda (Q: "Realm", pronounced [ˈarda]) was the Quenya name for the world as a whole. Arda was created within Eä by Eru Ilúvatar. It was then shaped by the Valar, with continental masses such as Middle-earth and Aman, and oceans, like Belegaer.
Cosmology is the structure of the universe, its creation, and divinities.
Eä was created by Eru Ilúvatar and the Valar in the Ainulindalë. Within it, there is Arda, the world, with its geography and such physical features as the layers of the atmosphere, the Vista, and above it, Ilmen and Vaiya. Above, it was Menel with the stars and constellations.

Arda was first brought into existence with the Music of the Ainur, for the purpose of creating a home for the Children of Ilúvatar. Ilúvatar appointed the Valar as its masters, and was built mainly by Manwe, Aule and Ulmo. They invented its geography, for at the time it was largely without feature and gave it symmetry and form. But then Melkor wanted Arda for himself, and the two sides engaged in the titanic First War where Arda was marred and its plan was altered.
As for light source, the Valar decided upon two lamps. One, a blue light, was placed at the north, and it was called Illuin. The other, a golden light, was placed at the very southernmost point, and was called Ormal. Aulë, craftsman of the Valar, forged two towers: Helcar and Ringil, placed at the north and south respectively. The Valar chose as their own home the green isle Almaren.
It was at that time that Melkor made his first attempt, spreading chaos across Arda. He destroyed the Lamps and the Towers, ruining the symmetry of the world. Continents formed: especially Aman, Endor, the Dark Land, the Hither Lands, and the Land of the Sun. So Arda was created.
 Before the Shifting
Arda was originally flat, like a plate. Encircling the continents was Ekkaia, the Encircling Sea. Farthest to the West was the great continent of Aman, composed primarily of two geographical features: the Plain of Valinor, and the Pelóri Mountains. Taniquetil was the highest mountain in this range, and in the world. To the east was the great sea of Belegaer.
Across Belegaer, to the north, was Endor, or Middle-earth. The west side of this land mass was called Beleriand, the north Dor Daidelos, and the east Palisor. According to Tolkien's earlier maps, it was in Palisor that there was the great inland Sea of Helcar, and the shores of Cuiviénen. Middle-earth was dominated by many mountain ranges and forests.
To the farthest east possible was the Uttermost East, with a great curved mountain range called the Wall of the Sun. In the Ambarkanta it is called the “Dark Land of the Sun”. Corresponding to Taniquetil was the mountain Kalormë.
 Second Age and Beyond
During the tumultuous War of Wrath, the Valar broke and reshaped much of the world. The most prominent change was the drowning of Beleriand. Also Ossë raised Andor – a large, star-shaped isle – out of Belegaer.Drowning of Númenor. The world was stretched and made into the shape of a sphere. The continents shifted. At that time Aman and the island of Tol Eressëa were removed from the Circles of the World, and became inaccessible save by the Straight Way.
The Elves held to the concept of Arda Marred. In the beginning, at the time of the Music of the Ainur, was Arda Unmarred. According to the idea of Arda Unmarred, the world was originally “unstained” by evil. It became Arda Marred after Melkor entered and introduced chaos. They also clung to the idea that one day the world would become Arda Healed. According to this belief, Arda Healed will not come about until the Dagor Dagorath, the Last Battle.
 TengwaQuenya of the twenty-sixth letter of the Tengwar alphabet. It is a modification of Rómen (letter 25). In written Quenya Arda is used for RD. In other modes this letter represents voiceless R (or RH). The Westron name for this letter is Rhó.
 Other names
Arda is the Quenya name of the World, with its atmosphere and the celestial objects. The term Ambar is roughly equivalent and it probably refers to Earth without the celestial objects. It was also called Kingdom of Earth/Arda/Manwë and Little Kingdom.
 Other versions of the Legendarium
In the next phase of the legendarium, as described in The Ambarkanta, the world has the Qenya names Ilu (being the wholeness of existence, the world, with its sky and air, equivalent to Arda of the later Legendarium) or Ambar (being the "earthy", concrete part of Ilu) suspended in the Void.
Arda first appears in a later version of the Ainulindalë from 1951, where the term "Ea" also appears, with Arda now being just a small part in the vast regions of Creation and not equated with it.
In the later Round World version of the Silmarillion, there is the consideration that there are other worlds in Ea beside Arda where the innumerable Ainur labored, but Arda is of central importance in the Great Tale of Eä, as it is the stage of the conflict between the Great Enemy and the Eruhini. The distant worlds, and the Ainur who shaped them, are beyond the thought of Elves and Men.
