Chaos

The incoherent cacophony of random notes. Raw potential, without order. Through order, those notes can be formed into song, and with song, comes reality itself.
Humans and Dwarves misunderstand Chaos to be the God of the Elves, but this is not actually so. The Elves understand Chaos to be the natural state of disorder. The building blocks of reality, but not reality itself. They are curious about it, fascinated by it, but they neither personify it nor worship it.

Localization

The Elves believe the Veil may be Chaos itself. The edge of reality into unreality.
