Defenders of the Realm: The Dragon Expansion provides the means to ramp up, ease up, expand and customize your Defenders of the Realm gaming experience in a variety of ways. The three new Dragon Generals (Onyx - black, Hemlock - green, Brimstone - red) can be used with Sapphire, the original blue Dragon, in a struggle that will severely test the mettle of the Heroes of the Realm. The new General card for Sapphire gives her an additional hit point for each other Dragon in play.
