While this is in fact an actual Master Gemstone, the only mention of it is in an Alternate Universe book by another author. (Xena13a's Legend of the Hybrid) The main function is translating every language on either the user, or those within the area. Inside the LoE plot, it is considered one of the King's Boons, artifacts scattered through space-time.
