Eru The One is the one and only creator of the universe. In the beginning it was Eru, The One with no beginning and no end. He/she created the Timeless Halls then he/she fashioned all time, all scientific laws, all matter, all space and all universes by his/her hands. He/she then created the parallel spiritual planes for each universe; these dimensions were called the Ethereal Planes and were divided into two sub-divisions: Atrii and Irina. Eru The One is invisible, too holy to be seen by mortal eyes.


Eru is the supreme Creator God in Tolkien's legendarium, mentioned in The Silmarillion.
