The Jewel of Memory is an artifact that is significant to the Great Dragons and all dragonkind. It is a great memory crystal, one of the methods dragons use to store information, shaped roughly like a large metahuman-sized egg, and supposedly stores all of the wisdom and knowledge of dragonkind from the previous Worlds. Possession of the Jewel comes with the title of "Loremaster."
It was previously owned by Dunkelzahn and was given to Lofwyr by the late dragon's will. It is rumored that there was a great contest among the Great Dragons for the ownership of this Jewel, but it appears that Lofwyr has retained possession of it.
