Sub-creation
From Tolkien Gateway
Sub-creation
Creation by the Ainur, Elves, Dwarves, and the race of Men (including Hobbits), all of whom are themselves creations by Eru Iluvatar or in the case of the Dwarves, by the Vala Aule and given life by Eru. It is called 'sub-creation' because original creation is the province of Eru alone, and that which is made by those created by Eru is derivative from the works of the One.
