Beyond the vast Transylvanian forests of Romania, hidden deep within undiscovered caves of the rugged Carpathian Mountains, are the homes of many of the oldest species of dragons on earth.

They have lived for thousands, some even millions, of years in the deepest part of the earth’s crust.

The oldest of all is wise Lumea, the greatest teacher of young dragons. His newest student, Tanarul, is a mere 200 years old. The two of them are embarking on a world tour to meet and study both the Greater Dragons of history and the tiny Lesser Dragons, all of whom have personal stories to tell about their legendary encounters with humans throughout the centuries.

Lumea has very little use for humans and, prefers his entire species remain known as legendary creatures of myth, rather than risk association with that troublesome race. Tanarul has problems being considered a myth, but respectfully follows his teacher’s wisdom in the matter.

Throughout their global discoveries, Tanarul is introduced to dragons of fame, such as the nine headed Hydra of the Hercules fables; Tiamat, the goddess dragon of Ancient Mesopotamia; Quetzelcoatl, the feathered serpent dragon of the Mayan culture; Cosmina, the granddaughter of the dragon of St. George, the toxic Basilisk; the Bunyip, the bulldog-faced dragon of Australia; the gigantic Behemoth, and dozens more of the most feared creatures of human history. From them, Tanarul is educated in the dragon’s point of view and learns the truth about his civil and misunderstood species.

But their journey quickly takes a turn toward high adventure as they discover the unstable state of their natural world, caused mainly by humankind’s destruction and disregard for the ecology. The polluted oceans and melting ice caps are causing problems for dragons and humans alike. The great dragon Leviathan, who has grown to be the length of Ireland, has begun to stir from his hibernation in the North Pole. His wanderings could destroy the planet. There is only one choice. The League of Dragons must find allies among the humans to save both their races.
