The caves of chaos have been cleansed but an intriguing tunnel was found in the process. Seemingly blocked to bar access, the tunnel plunges deep into the earth. Just inside, a black, marble obelisk rests in the middle of the passage. A single rune – the sign of the dread arch-mage Hilgdred – is the only mark upon the obelisk. Of what concern can the storm wizard have within the Deep?
Beyond the Caves of Chaos is an adventure designed for four to eight characters of fourth to sixth level using the Fifth Edition game rules.
