Lair of the Frog King is a short adventure for five 1st-level characters that takes place in an ancient castle. The river—which used to flow around the castle and fill its moat—has diverted over the centuries, and now what used to be fertile farmland is marshy bog. What’s more, the swamp has claimed the castle itself. A tribe of bullywugs settled in the muddy former fortress, and use it as a base to raid nearby farms. Can the newly-minted heroes stop the bullywug menace? Find out in Lair of the Frog King!

A young black dragon and two hatchling dragons live in an excavated sandstone burrow in the swamp west of Knacker Knob. Connected to the dragon lair is a complex of sandstone tunnels and chambers inhabited by lizard men. Some sandstone tunnels and chambers are partially flooded, and others are filled with nasty things such as slimes, oozes and gelatinous cubes. The lizard men revere the dragons as magical spirit guardians. In small groups the lizard men are easily defeated, but if allowed to prepare a common defense, the lizard men tribe with its spellcasters may present serious threat to the player characters (PCs). Wild Dragon Den is the first dragon's lair to conquer. Part of TSR 1073 The Dragon's Den

Arden, Duke Regent of Tyndall, fears that the dead have risen to haunt the living. Is he right?
