Dungeons and Dragons 4th Edition adventure for a party of 10th level characters.
From the back cover
Over a century ago, the nation of Cerra was terrorized by Vulkanon, a fearsome dragon that rose out from an active volcano on a small neighboring island.
To deal with the threat, the council of Cerra hired a group of adventures led by Raylen Darathar—a powerful elemental mage—to seek out of the dragon and destroy it. Raylen emerged mortally wounded, but alive. The volcano was silent, and the attacks stopped. Cerra believed itself to be safe once again.
But decades have passed and now evil stirs again. As the volcano begins to tremble, fearful rumors spread that the great dragon has somehow returned. Sailors whisper of a dark mage that has managed to resurrect the dragon and intends to use its power cower the land into submission. Cerra seeks heroes once again to save itself from fiery destruction.
