A Dungeon & Dragons Adventure: The Curse of the Vierme's

The Curse of the Viermes is a trilogy of single-session adventures designed to take a group of 1st-level characters to 3rd level. 

Masquerade of the Viermes takes the party through the manor, encountering various monsters and challenges.  They discover that the Baroness has been killed by a monstrous worm, the Vierme's Slither, and that the manor is infested with these creatures.  They also encounter Count Ibilis Vierme, the manor's lord, who has been driven mad by the Vierme Curse.  The party must defeat the Vierme's Slither and deal with Count Ibilis before they can escape the manor.    

The Caleuche's Cry sees the party set sail for the island of Ooaahhuu, where they hope to find a way to lift the Vierme Curse.  Along the way, they encounter the ghost ship Caleuche, which is now under the control of the Rat King.  The party must defeat the Rat King and free the Caleuche before they can continue their journey.    

The Blight of Ooaahhuu takes the party to the island of Ooaahhuu, where they must find the Temple of Pele and return the Eye of Water, which was stolen from the goddess.  They must navigate the treacherous swamp, battle the Cron, and solve puzzles to reach the central chamber.  Once they reach the statue of Pele, they must return the Eye of Water and seal it with Vierme's blood.  If they succeed, the curse will be lifted, and the island will begin to heal.
