The raven game - Caiseal Mor

The Raven is a carrion creature and its tale is one of blood and death.
After years of feuding and bloodshed, Innisfail is divided by war once more. The Watchers, an ancient and malevolent pair of troublemakers, are impatient to be released from their bonds of immortality. They have promised to visit their bloody vengeance on Innisfail for many generations to come should Eremon of the North gain victory over his brother Eber of the South.
As it stands, Eber has no hope of matching his brother in numbers or arms, and when a poet-king and his red-capped warriors arrive from across the sea, it seems he has yet another enemy preparing to move against him. Amidst this chaos and confusion, the Druids Dalan and Sorcha seek to track down the mystical Draoi song - possibly Innisfail's only hope of undoing the Watchers' evil influence, and the only way to bring peace to the land at last.
But the Raven is also one of the aspects of the Morrigan, goddess of war, and few may escape her claws...
