The Dwarven Rivergate

Publisher's blurb:

On the way to the dwarven city of Hakku there's an old rivergate now infested with goblins and orcs. Passing the rivergate can save over a days worth of travel time, but it is a known fact that taking this route usually means only trouble. The creatures that have taken over the rivergate are ambushing any travelers who are careless or adventurous enough – or in so much hurry – that they choose to take this route to the city of Hakku.
