You are one of the few casters who has learned the deepest secrets of magic, namely the existence of Aether, the primal force that drives all magic. Your studies allow you to utilise Aether to mould your spells and gather some of the lost power of a bygone age.

You have a number of Aether points equal to your proficiency bonus. These points refresh when you take a long rest.

During a short rest, you can spend Aether points to change the same number of spells on your prepared spells list.
