Uul'Kur (Dream Key)

This iron token is inlaid with a sliver of a Siberys dragonshard. Most are worn as brooches, but others take the form of coins or keys. While an uul kur is a common magic item, the secret of their creation is known only to the chot'uul monks of the Heirs of Dhakaan, and they are largely unknown in the Five Nations. When you sleep with an uul'kur on your person, you remain fully lucid when you dream, and when you wake, you clearly remember everything that transpired. If you understand the workings of the uul'kur, you can use an action to bind it to your dreams until dawn the next day. While bound, any creature who sleeps with this token on its person shares your dream instead of creating its own, provided you are asleep at the same time.
