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

Do you want your players to feel like they are in a zombie movie, struggling against a deadly horde that tries to surround them, overpower them, and bear them down to the ground to be devoured? This is an adventure that can threaten even the stoutest of characters, and is not recommended for parties of levels 12 or below unless they are larger than normal. This module is designed to take 4-8 hours of play and cover a single day, depending on the party’s speed of play and how thoroughly they decide to explore. It includes suggestions and some plot hooks that can be used to tie this easily into a variety of long-running campaigns, or it can be run as an indepdent adventure. The players will come upon a sacked town, figure out what happened, track an item whose theft has ominious implications for the region, and explore a partly-flooded old temple to end the threat. It's primarily combat-focused, but there are a few areas where exploration and route choice makes a difference, as well as traps if the party goes for the optional temple treasury. The antagonists in this module are mostly ghasts and ghouls, but the module title and cover page are deliberately selected to not spoil this. These are greater ghouls and ghasts that can challenge higher-level characters, backed up by mobs of lesser ghouls that can surround, paralyze, and devour the weak and unlucky, led by a Warlord whose aura can drive even the stout-hearted into forgetting their plans in a moment of madness.
