Revival of the Dragon Emperors is the first expansion released for the Alteil virtual collectible card game. It introduces 100 new cards to the game, and among them can be found the various types of Dragon Kin that call the world of Lavato home. Though they represent a fierce addition to any card file, the common dragons pale in comparison to the paragons of their kind, the Dragon Emperors; each of the four spheres includes one of these powerful character cards.
