I need a name for an item for an artifact that allows the user to tap into a vast amount of arcane related information, as well as (logically) adding a + to arcane knowledge checks. The users ability to utilize the artifact is limited their understanding of the arcane, numbers which i haven't gotten into yet. I dont really know what to name it though, or what it should look like. I'm picturing a fist size metal engraved cube. I've thought of names such as the Arcane Cube but they dont really seem all that interesting to me. Any suggestions?
