Important: The adventure is 1e but it has monster conversion notes for D&D 4th edition The town of Highport, once a human community overlooking Wooly Bay from its perch on the northern coast of the Pomarj, fell prey to hordes of humanoids swarming out of the jungle-covered hills surrounding the settlement. Though the orcs, goblins, kobolds, ogres, and gnolls razed much of the place in their ferocious rampages, the smoldering ruins they left behind soon became a new kind of community, a place of trade between the humanoid “locals” and the unsavory human traders who have no compunction about doing business with them. Slaves are a commodity in ready supply in Highport’s market, since many pirates raid up and down the coast of the bay, putting fishing villages to the torch and filling their holds with captured refugees. Slavery has become a thriving business in the town, and rumors abound of a cartel of Slave Lords who run things from behind the scenes, filling their coffers in secret from the buying and selling of human chattel. The trade has become so prolific that the good folk to the north have grown tired of these depredations and decided to fight back. Forces of righteousness and honor have recently descended upon Highport, some openly and others in secret, in various attempts to destroy the machinations of the Slave Lords and abolish the abominable enterprise that has taken far too many loved ones from home and hearth. One such doughty servant of goodness is Mikaro Valasteen, a cleric of Trithereon. Mikaro slipped unnoticed past the crumbling walls of Highport with a single mission: to rescue and transport as many slaves to their freedom as possible. Mikaro and a handful of faithful assistants located a number of escaped slaves—as well as rescued a few more not sufficiently restrained and guarded—and shepherded them through the gates and beyond the reach of their humanoid tormentors, returning them to their lands and homes. This covert freedom brigade enjoyed remarkable success early on, since the servants of the Slave Lords were often lax in their vigilance and sloppy in their efforts to prevent loss of the “merchandise.” After one too many shipments never made its destination, the humanoids stepped up their security and the normal channels of escape from Highport closed to Mikaro and his team. He cannot risk exposure by smuggling the freed slaves through the gates as merchandise any longer, since shipments of goods are now regularly stopped and checked. No longer able to free the slaves in that manner, Mikaro began hiding his charges in an abandoned villa in a particularly rundown part of the town. Although they are safe for the moment, their numbers have grown unmanageable, and the priest fears it is only a matter of time before someone slips up and brings slavers to their doorstep. Ever more desperate to find a new means of escape from Highport, Mikaro has started work on a plan that is both daring and dangerous. He intends to use a series of old sewers coupled with natural caverns running beneath the town as an escape route to the sea beyond the walls. But he needs someone to clear out the creatures and pitfalls he knows lie within. Pgs. 2-27

In the kingdom of Keystone, at the mouth of the Manyforks River, stands the port city of Barnacus. It was founded two hundred years ago, and its strategic military and commercial location has made it the second most important city in the kingdom. The city is under the rulership of Haermond II, Duke of the province of Elcadan, a half-elf of high esteem who has been in charge for more than a century. His outstanding commercial politics have made the city very prosperous; almost every trade company in this part of the continent has a counting house in the port of Barnacus. Because of this prosperity, the city has suffered many pirate raids, and thieving activity is a fact of life for residents and visitors alike.
