4. It was difficult from the very beginning, when the Dwarves committed the faux pas of being created before the Elves. What is the name of the Vala who created the Dwarves?
From Quiz The Troubled History of Elvo-Dwarvish Relations
Answer:
Aule
Aule, like his fellow Valar, was so excited about the coming of the Elves - "to have learners to whom he could teach his lore and his crafts" - that he couldn't wait and created some beings of his own. Because the form the Elves were to take was unclear to him, he made the Dwarves "even as they are now". Although they seem happy as they are, is it possible that the Dwarves' jaundiced attitude toward the Elves springs at least partly from bitterness at their own lack of height, unearthly beauty, and wonderful singing voices?
In any case, Iluvatar, master of the Valar, would not permit any other people to appear in Middle-Earth before his own creations and the Seven Fathers of the Dwarves were "laid to rest in far-sundered places" to sleep until their better-looking counterparts had gotten to make their own appearance. Elvo-Dwarvish relations were off to a bad start.
