History
In 1345 DR, Kazgoroth, the Beast, came into the world to destroy the power of the Earthmother. Changing its shape as needs be, the Beast went across the island of Gwynneth, corrupting everything in its way. Its destination was a large gathering of Northmen raiders at Oman's Isle, in the middle of the Moonshaes, where they were preparing an assault on the kingdom of Corwell. They didn't know that their leader wasn't King Thelgaar Ironhand, but the Beast, who killed the king and assumed his shape.

Meanwhile, the Earthmother, aware of the danger and hurting from the corruption brought to the land, her body, by the vile presence of the Beast, awakes her children - the Leviathan, the Pack, and Kamerynn, the unicorn. They will try to stop Kazgoroth in different ways, but that won't be enough.

At Caer Corwell, the seat of the king of Corwell, rumor brings word of war coming to the kingdom. Preparation is under way, but the Ffolk don't know where the enemy will strike. It is up to Tristan to organize the Ffolk against both human and demonic threats. In his fight against the odds, helped by Robyn, he will grow into the responsible leader that should inherit his father's kingdom.

In the, the Fey city of Karador rose from the waters of the Myrloch on the Island of Gwynneth. The noble leShay High Lady Ordalf proclaimed herself queen of the Island. The human kingdom of Corwell, and it capital Caer Corwell fell into ruins.
