Aether

A rare substance found only in the volcanoes of the Ember Dominance.
The material/substance that fills the entire world and heavens, Arcane is the element that explains phenomena like light and time. It is the magic element that holds together souls and the other elements, forming the borders between each. Subtler than light, penetrative and non-material. Arcane is associated with otherworldliness, the unexplained and unknowable, also insanity and madness. Alchemy component is Aether, found only in the Aether Well in the Ember Dominance. It seems to have no other purpose and doesn’t fit on the Alchemy element list but draws out the Arcane power of a soul. Aether is found as solidified indigo ore veins without a hard shell, creating a strange effect as it looks like the inside of an ore vein but without the stone. It is most used as a crystal for a component but can also be crushed into small spores to be used.
