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.
