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

Stormy seas rock your vessel, tossing her about like a toy in the jaws of a hound. Thunder rolls in the distance. Then, an arc of lightning splits the sky, and the sound like an exploding fireball all but bursts your eardrums.

The last thing you hear is the cracking of wood as the deck explodes into splinters, and the ship is torn asunder. All goes black.

Every year, on the very same day, the city of Cape Coral has been besieged by a giant Kraken, killing dozens of people and destroying huge chunks of the town. That day this year is approaching quickly -- in fact, the town has only two days left to prepare. Princess Lua, the daughter of the former king of Cape Coral, has reached out to the party to beg their aid in protecting the town. The Kraken is far too formidable a foe to try to attack alone, so instead the party must convince as many factions of townsfolk as they can to aid them in the fight, set traps, and fortify or evacuate the town. After their two days are up, the Kraken attacks, and the party, supported by whoever they managed to convince, must face it in battle. Along the way, though, the players have a chance to figure out why the Kraken attacks in the first place -- and, if they are quick and clever enough, they can stop the attacks for good.

Folks may go there to relax or to look for work, to celebrate or to mope, to learn the latest or to forget.

Watch out for pirates! * Stop a dark ritual to save an innocent—and yourselves. * Come to the rescue when there’s an accident by the pier—and the predators arrive.

Deicide is a campaign designed to begin with a party of four to six 1st-level characters, who should advance to 20th level by its conclusion. The Gods have abandoned Faerûn. Bringing loved ones back from the dead hasn’t been done in centuries, and communion with the deities is a spiritual exercise only. Holy warriors and messengers have lost their powers and have all but completely disappeared. In this bleak world, wars are frequent, crime runs rampant, and hope has faded. Rumours are abound of a mysterious crime lord taking control of the underworld. Monsters roam the lands and every road is increasingly more dangerous. Without guidance, the many civilizations of this world are plagued by greed and corruption. The only way forward is to bring the Gods back, or to take their place in the heavens. Deicide takes place across two islands, Aurora and Limdorkal. These landmasses are the westernmost islands of the Moonshae Isles, an archipelago located roughly 400 miles west of the region of Amn and to the southwest of the Sword Coast. Surrounding the Sea of Moonshae, these islands feature a wide array of cities, civilizations, climates, terrains, and monsters. Limdorkal is famously a harsher environment, home to exotic races, whereas Aurora is almost entirely dominated by the human kingdom. Elminster Aumar, the famous Old Mage of Faerûn, once visited these islands and claimed it surprising how such diverse environmental systems erupted here, and how varied were the people inhabiting them. While the Sword Coast is part of Faerûn, a continent of Toril in the Forgotten Realms, feel free to adapt these islands to any setting of your choice, such as Ravenloft, Eberron, Ravnica, or even on your homebrew world. The story told here happens some hundreds of years after the beginning of 5th Edition, and the Overgod Ao is trapped inside an artifact, which limits the workings of gods around Toril. The characters will be able to learn more about the missing Gods, about a mythical folklore artifact known as the Wand of Wonders, which carries the powers of the Gods, and about the crime lord Kaiser Soze. Through their adventures, they will be able to visit other realms, planes, and dimensions, as well as come into contact with different races and civilizations. In the end, it is up to them whether to ally with the Crime Lord, and whether to release the Gods or keep their power for themselves. This campaign can work as a loose set of modular adventures, which can be easily picked separately and played as one-shots of different levels. Even their locations on the map might be moved, and events happening in particular towns can happen on others. The adventures include dungeon crawls, murder mysteries, sandbox urban quests, exploration on land and in the seas, inter-planar travelling, among others.

A desperate rescue beneath the waves. The Deadly Sea is an oceanic quest for 4-8 characters of 4th-7th level in the AD&D® game.

See additional notes in the section ‘‘For the Dungeon Master.” The adventure begins at a seaport which the Dungeon Master should name and develop as desired, to fit the circumstances of his campaign. The names of other areas may be changed to fit the campaign as well. This module requires some detailing and planning prior to use.
