Oneirium

Oneirium is a substance that, like dreamstones, help those who possess it enter into the Plane of Dreams. Oneirium, unlike dreamstones, is a substance that must be imbibed or consumed for its effects to be felt. It is a sticky, gooey substance extracted from a few succulents that grow naturally on Nilgoav Island. When consumed, the effects of Oneirium manifest, and the user slowly drifts into the world of dreams. Most commonly, a dab of the substance is added into pipe weed, and smoked.
