The Lorekeeper's Tome

The Reach is reckoned in seven regions, but there was an eighth - a kingdom drowned in the Cataclysm, when the Gulf tore open and the flood swallowed its land whole. All that remains above the water is its volcano: a small, ruined island at the very centre of the Gulf, hidden these three thousand years behind the eternal storm. It cannot be walked to; it can be reached only by sea, and only once the storm is gone. What waits upon that island is the last and most guarded matter of the whole journey.
