Lore

True dragons are winged reptiles of ancient lineage and fearsome power. They are known and feared for their predatory cunning and greed, with the oldest dragons accounted as some of the most powerful creatures in the world. Dragons are also magical creatures whose innate power fuels their dreaded breath weapons and other preternatural abilities.
