She is only mentioned briefly in the Valaquenta, where she is described as one of the chiefs of the Maiar. In The Book of Lost Tales, it is implied that she was supposed to be the daughter of Manwë and Varda, but Tolkien appears to have changed this in the Silmarillion and most readers accept that she was simply created by Ilúvatar like the Valar. Soon after, Tolkien abandoned the idea of the Valar having children altogether.
Her name was possibly inspired by Kalevala, where one of the heroes is called Ilmari.
