In 1798, Ireland stood on the edge of open rebellion.

As unrest spreads across the country and the grip of British rule tightens, a darker threat begins to stir beneath the bloodshed. The Emerald Oath, an ancient vow forged before mortals came to rule Ireland, guards a secret tied to a darkness now beginning to seep back into the world.

Bound together long before they were born, a group of allies are drawn toward the same dark truth. As violence spreads and the line between fate and choice begins to blur, they must decide who to trust, what they are willing to sacrifice, and whether the bonds they have forged through friendship and love can survive what is coming.

Because if they fail, Ireland will have far more to fear than rebellion. A darkness is rising, and it will not stop until the land is reclaimed by forces seeking to hold unimaginable power.
