Eru is transcendent, and completely outside of and beyond the world. He first created a group of angelic beings, called in Elvish the "Ainur," and these holy spirits were co-actors in the creation of Arda through a holy music and chanting called the "Music of the Ainur." He is known also as "the All-Powerful".
Eru is an important part of the stories of The Silmarillion but is not mentioned by name in Tolkien's most famous works, The Hobbit and The Lord of the Rings (He is alluded to as "the One" in a part of Appendix A that speaks of the downfall of Númenor).
Eru alone could create independent life or reality by giving it the Flame.
Elves and Men were created by Eru directly, without delegation to the Ainur, and they are therefore called "Children of Ilúvatar" (Eruhini). The Dwarves were created by Aulë with the belated blessing of Ilúvatar, though they would be second to the Children of Ilúvatar. Ents were also created by Eru under the request of Yavanna who reasoned that Dwarves would want to fell trees. Melkor instilled some semblance of free will into his mockeries of Eru Ilúvatar's creations (Orcs and Trolls).
The first things that Ilúvatar created were the Ainur (from his thoughts). He then bade the Ainur to sing to him; this was called the Ainulindalë, or the music of the Ainur. Melkor created a discord to the music, and Iluvatar added three themes to the Ainulindale, which talked about the fate of Arda.
The next thing he made was Eä, the "World and All That Is", and Eä was in the Void (Melkor was drawn to the Void, and so at the beginning of Arda, he lay in the Void, or the Outside as it was sometimes called). He then gave the Ainur the option to go into Eä and fashion it as they will. The Greatest Ainur who chose to do so were called the Valar, and they controlled the shaping of the Arda. They could not make life, however, as Aulë proves, who was able to give only shape to the Dwarves, while consciousness was given to them by Eru. The Valar were accompanied by the Maiar, the lesser Ainur. The elves and men, however, came directly from Ilúvatar's thoughts, and are referred to in The Silmarillion as The First Children of Ilúvatar and the Second Children of Ilúvatar, respectively, while the Dwarves would be the Adopted Children.
- During the Years of the Trees, Eru created and awoke Men.
- In the Second Age Eru, called upon by the Valar, buried King Ar-Pharazôn and his Army when they landed at Aman in SA 3319. He caused the Earth to take a round shape, drowned Númenor, and caused the Undying Lands to be taken "outside the spheres of the Earth".
- In a letter written by Tolkien, he stated that Eru again intervened, this time in the Third Age, causing Gollum to trip and fall into the fires of Mount Doom while still holding the One Ring, thus destroying it.
Eru meant "The One" or "Alone", and the epithet Ilúvatar meant "Father of All" in the Quenya tongue.
- Eru's role could be seen as similar towards the role of God himself from the Abrahamic religions, and was likely based entirely off of the same being, given Tolkien's faith.
