The Story in Brief
A party of unlikely travellers converges on the town of Monsoth and is drawn westward toward Osgog — the Black Lake at the edge of the known world. Along the way they encounter the legacy of ancient gods (Torval, Ceridwen, Mons), face the reach of The God King, and are guided — and tested — by the inscrutable The Boatman.
The campaign spans The Cradle (the world’s living heart), the ruins of old civilisations, sacred stone circles, and a waterfall that falls into the night sky.
