The Dwemer erased themselves from all existence by using the tools on the heart of Lorkhan, therefor binding their souls to the skin of the numinduim and erasing themselves from all existence. Only one single Dwarf was left, whom we met in Morrowind. Vivec himself couldn't sense the Dwemer at all in any realm or plane of existence. They are erased.
