From publisher blurb: The strongest and most clever dragons live so long that mere wealth no longer interests them. They hoard power, over individuals, nations, and even reality itself. Some of these great wyrms may choose to invest a portion of that power in mortals, forming pacts that turn arcane dabblers into warlocks bearing the marks of ancient draconic magic. Power of the Great Wyrm presents a new Otherworldly Patron for your warlock characters: the Great Wyrm. Call on ancient magical secrets to enhance your pact boon and even learn to transform yourself into a dragon!
