Aeon Stone (Crescent)

Over millennia, these mysterious, intricately cut gemstones have been hoarded by mystics and fanatics hoping to discover their secrets. Despite their myriad forms and functions, these stones are purportedly all fragments of crystal tools used by otherworldly entities to construct the universe in primeval times. When you invest one of these precisely shaped crystals, the stone orbits your head instead of being worn on your body. You can stow an aeon stone with an Interact action, and an orbiting stone can be snatched out of the air with a successful Disarm action against you. A stowed or removed stone remains invested, but its effects are suppressed until you return it to orbit your head again. There are various types of aeon stones, each with a different appearance and magical effect. Each aeon stone also gains a resonant power when slotted into a special magical item called a Wayfinder

Once holy relics, the creation of crescent aeon stones was inspired by Acavna, goddess of the moon and protection. The crescent aeon stone continually sheds dim light in a 5-foot radius.

The resonant power enables you to cast Forbidding Ward as a divine innate cantrip.
