Now, its for- lorn dome the roost of seagulls, its secrets slumber beneath the waves.

Inspired by the "Happy Fun Ball" from the web series Critical Role, The Cube of Vanya is a magical adventure through demi-planes created by an ancient wizard, now destabilized by a malevolent dragon. The adventurers find themselves trapped within a series of themed planes with no idea how they got there. Navigating these planes to find a means of escape, they uncover the secrets of the cube while piecing back together their own memory. During the campaign the adventurers may fight shadow demons in an inn which is really a prison, flee a tornado while perched perilously in the sky, forge a weapon within a volcano, and much more. The module is structured in a non linear manner allowing the adventurers to choose their own way, or for the DM to pick and choose their favourite bits to highlight. The adventure was written with four level 5 players in mind but it would be easy to tweak for different sized groups around that level.

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

The Sea Witch is a short adventure for four 10th-level characters. The difficulty of the adventure can be adjusted by changing the level of main antagonist (Black Molly, the sea hag pirate) or by altering the number of her ogre servants. To tailor the encounter to groups of different levels, refer to table 4-1 in Chapter 4 of the DUNGEON MASTER’S GUIDE. The adventure is set off a lightly populated coastline known as Misty Bay, but adapts easily to any coastal region in existing campaigns. The sea hag known as Black Molly is a notorious pirate who has plagued the coastal cities for the better part of a decade. A successful Knowledge (local) check (DC 15) will reveal that Molly and her ogre crew have a filthy reputation as merciless killers who delight not only in plundering vessels for their riches, but also in destroying the ships themselves and sending all hands to the bottom of the sea. Now the villain and her followers have seized control of the Old Lighthouse of Misty Bay located off a lightly populated coastline. For generations the lighthouse beacon has protected the fishermen of this region, warning them of the dangerous rocks that lurk just below the level of the high tides. Recently, the hag has put out the beacon, darkening the lighthouse; misery and destruction are sure to follow as ships start to blunder into the rocks. Blackmail is apparently Black Molly’s aim in this venture: She conveyed a message to the nearest shore community, the fishing village of Poisson, demanding the princely sum of 50,000 gp. Until she receives this ransom, she intends to hold the lighthouse and its beacon hostage. The fate of the human keepers who tend the lighthouse is unknown to the seaside communities at this time, but they fear the worst. The Sea Witch is ostensibly a rescue mission: The PCs are pitted against the evil of Black Molly and the brawn of her savage ogre crew. It is the heroes’ task to retake the lighthouse and, if possible, free its captives from the clutches of their jailer. What neither the PCs nor the shore communities yet realize is that while she 1would be pleased to have the gold, Black Molly is in fact after bigger treasure. Molly has no intention of giving up the lighthouse — at least, not until she finds what her master sent her here for. Lying on the sea floor practically at the base of the rock on which the lighthouse sits is the wreck of the war galley Flying Cloud, which according to popular legend was captained by a cleric who wore around his neck an amulet of the planes. Black Molly wants this prize, but so far she hasn’t been able to find it. She’s scoured the wreck without finding any sign of the magic item. Now she’s trying to determine where to search next, for the item might well be somewhere near the wreck. If she can’t find it, she’ll start torturing her captives to find out if they have any useful knowledge about the amulet.

The sleepy village of Raven's Lake has a secret: A terrible god lives in the depths of the settlement's namesake. The citizens of Raven's Lake know that something lives in the lake. People who go out on the lake after dark go missing far too often and frequently turn up weeks later with no memory of where they've been. The local church of St. Cuthbert has been abandoned no fewer than seven times in the last two years, each time its lone cleric packing hastily and fleeing town without a word. Adventurers who come to Raven's Lake have a habit of vanishing forever. The truth is that something does indeed live in Raven's Lake but it is far from a deity. It's an exiled aboleth by the name of Zlorthishen. Pgs. 33-36
