Anandak, a red dragon, has taken over an abandoned dwarven stronghold as his lair. He has also assembled together a rough confederation of monsters to act as his bodyguard. Anandak is preparing to enter into an alliance with the Black Prince, the March Lord Draven. The plan is for Anandak's monster allies to terrorize the lands north and east of Knacker Knob while the Black Prince, on pretext of marching to the aid of Knacker Knob, take control of Knacker Knob and the surrounding region. An emissary from the Black Prince, Lord Gonzaga, is currently in the dungeon, and he is in possession of papers that might reveal the Black Prince's treasonous plot. The lair is horribly overcrowded because monsters of all tribes and gangs are gathered to take counsel with the red dragon. Monsters are sleeping in the hallways because there is so little room, and the antagonism between races is at flash point. The PCs may be able to fan these resentments into intermonster battles. League of the Red Serpent is the third dragon's lair to conquer. Part of TSR 1073 The Dragon's Den

Having already explored the northern reaches of their new domain, the PCs must now venture into the wilds to bring the rule of law to the south. Wicked fey inhabiting a ruined keep, undead haunting an ancient barrow mound, and others must be defeated to make the region ever more secure. Along the way, the PCs might also have the opportunity to ally themselves with some of the region’s local residents, including the dryad druid Tiressia, her satyr consort Falchos, and a band of gnome explorers called the Narthropple Expedition. In addition, the PCs will be called upon to mediate between two rival factions in the area: a group of independent loggers and the angry fey sorceress who opposes them.

Meanwhile, the PCs must deal with events within their burgeoning kingdom—a rabble rouser seeks to oust the PCs from their positions of power, the secretive cult of the hag goddess Gyronna has infiltrated the town, and a werewolf is preying on the townsfolk. All of these events build to the adventure’s twin climaxes: the sudden assault on their capital city by an owlbear of unprecedented size and the expansion of Hargulka’s trolls into the north.
