The Durants

"There's historical documentation of men who absorbed chaos energy into themselves and went quite mad with power. What with it being limitless, it's almost to be expected if you dare to use yourself as a vessel. Otherwise, it's perfect for fueling things that require energy to function. Constructs or machinery, powerful spells or incantations. The latter which can be made only stronger than what you could cast under your own power. Very good at expanding your abilities, you see."
