Dream Seed
Dream Seed is an artifact with a set of complex properties. Seven Dream Seeds were created altogether, but the two first ones were destroyed. The location of the surviving Dream Seeds has always been kept in secret, although their role in shaping the history of the Continent is well understood in some cases.
Dream Seeds could be argued to be the most important artifacts on the Continent. They are the center of the major religion Davinia, as well as the basis for the culture of whole peoples, most notably the Kwalee.
