Heroes of Trollstone

From the introduction: North of Elvritshella lies a region variously known as Trollstone, The East Crag Wirral and Travelmeet. A road runs north from the gardens of the elves, following the winding route of the River of Mist. This passes through Thumblegrain woods and beneath the hill fortress of Castle Groan - where it is said monstrous creatures inhabit the ruins long abandoned by men - before passing a small and inconspicuous looking inn on the eastward bank of the river.
