Eru Illuvatar

Eru Ilúvatar or The One is the single omniscient and omnipotent creator. He has been existing eternally in the Timeless Halls and possesses the Flame Imperishable in his spirit which kindles existence from nothingness.
== The Creator ==
Eru created the Ainur before anything else, whom he kindled with the Flame Imperishable. Each Ainu came from a part of his mind. To further their comprehension, he presented his thought in the form of music, and listened as the Ainur picked up his themes and elaborated on them, slowly learning to sing in harmony with each other. Eventually he showed them his greatest theme, and made them sing it in harmony and develop it with newly granted powers. This was the Music of the Ainur.
Out of this great music, Eru showed them the Vision which showed vast halls of spaces and stories unfolded in the deeps of Time, and some Ainur were drawn to it. Eru said "eä" ("let it be") and thus Eä, the universe, was created.
== The God ==
The Ainur entered Eä and shaped the world according to the Music. Eru delegated most direct action within Eä to the Ainur, including the shaping of the Earth (Arda) itself.
The Ainur were not omniscient and there were some things beyond their comprehension; those were the creation of the Elves and Men, who are directly the Children of Ilúvatar (Eruhíni) created without the delegation of the Ainur. Other things known by Eru alone are their destiny, and the End itself.
The activities of Eru in regard to the life of Arda or Eä are not clear. Manwë was the vicegerent of Eru on Arda and it is known that he sought for his consent several times, like before the creation of the Ents or before the Battle of the Powers. Instances of Eru's direct intervention were:
* Sanctified the creation of the Dwarves by Aulë, giving them life and sapience, and were his "adopted" Children.
* At the behest of Yavanna, he allowed the Ents into being.
* The creation of his Children, the Awakening of the Elves and Men.
* The Changing of the World something that the Valar themselves could not have done.
* Several coincidences and signs of higher providence throughout history, such as Bilbo Baggins finding the One Ring.
* The resurrection of Gandalf after he was killed by Durin's Bane, something that could only be done by an Authority higher than the Valar.:203
* The fall of Gollum into the fires of Mount Doom, thus indirectly causing the destruction of The One Ring and dissipation of Sauron.
Eru would someday enter Eä to save his Children. It is said that after the end of days, Eru will unite the Ainur and the Children of Ilúvatar to create a music even greater than the one of creation.
