They often swear with phrases such as 'by the first aether'. It is believed that people who have made poor choices are cursed to wait a long time until their next rebirth. Those that follow the aethers also hold that people return to the aethers upon their deaths to reflect upon their choices in life. They also believe humans were gifted with rebirth by the aethers to encourage, bless, and uplift their fellow people. They believe that aethers made all people, creating them to each think differently from one another. The aethers themselves believe collectively they are the equals of Adonalsium.

The people of the planet with primal aethers hold it as a sacred tenet that the aethers predate Adonalsium and are independent of its creations. While growing in such a manner, a sprouter is able to shape it by using Iron to pull the material closer, and Steel to push it away. It is unknown if that property applies to Aetherbound manifested substances. On Lumar the associated substance can continue growing if more moisture is added, until it maxes out. The substance they produce upon expanding also grows grey and dies when coming into contact with silver. Īll forms of Aether seem to be killed by silver and salt, turning grey and losing their reactivity when they touch it. Aethers have existed since prior to the Shattering of Adonalsium, and some believe that they predate Adonalsium itself or are totally independent from its creations. Those who are bonded to one of the twelve primal aethers and are able to manifest that aether are known as aetherbound. They originate on an unrevealed planet where the twelve primal aethers reside, although the aethers have since spread to other worlds of the cosmere.

Aethers are an ancient variety of Invested entities present in the cosmere.
