Sarkt is an illithid sorcerer. It was cast out of its community for its heretical studies (Sarkt was in fact, lucky to escape alive). It didn't take the cunning creature long to pick up a few thralls and find a new place to live, safe from the murderous intentions of its companions. Sarkt dwells in the subterranean ruins of an ancient shrine to Blibdoolpoolp, the crustacean-headed deity of the kuo-toas. This shrine lies on the fringe of a region controlled by kuo-toas, but since Sarkt's arrival, the fishmen avoid the area. A few unfortunate kuo-toas now serve Sarkt as thralls and maintain the illusion that the shrine serves Blibdoolpoolp. Pgs. 82-88

A Giant Ransom is a short adventure for four 11th-level characters. There are opportunities for diplomacy, stealth, and combat, based on the choices the PCs make, so any mix of classes is appropriate. The adventure can be set in any campaign world, in a frontier region near glacier-covered mountains. The newly appointed Duke Castaril Ambrinigan has recently relocated to a modest, newly constructed keep near the frontier town of Ormanlak. He and his family arrived safely, but a caravan containing family heirlooms was waylaid by a band of frost giant raiders. Most of the items were of no consequence to the Duke, with the exception of one: a three-foot tall golden statue of a lion. The Duke, wanting to avoid a war, sent an emissary to the frost giants. He offered gems totaling 10,000 gold pieces in value as ransom for the lion. The giants accepted, and a time and place was set for the exchange. But there is more. A white dragon named Whildenstrank lives in the midst of a nearby glacier, and has maintained a network of winter wolf spies, including some in the frost giants' camp. Through these spies, Whildenstrank learned of the capture of the golden lion, and the upcoming trade. Thinking that the lion would make a fine addition to his frozen treasure hoard, Whildenstrank has prepared to strike.

A "web Enhancement" adventure for the D&D 3.5 Frostburn supplement. Arctic / Frostfell / Cold Several decades ago, a down-on-his-luck half-elf known as Captain Kerakes lost his ship after a run of bad luck in a game of dice. So when an investor approached him with an offer of a new ship and three-month mission, he jumped at the chance. His new employer was a rich but somewhat miserly nobleman named Jarren Skein. Having heard rumors of the glacier dwarves and their amazing weaponcraft, he had become obsessed with obtaining some of their weapons as trophies. Skein made Kerakes the captain of a ship called the Rusty Walrus and promised him a sizeable commission upon his return with the desired glacier dwarf weapons. The PCs must board the wreck of the Rusty Walrus and defeat the undead that infest it. Later, the ghost of Captain Kerakes begins to wreak vengeance on Jarren Skein s heirs. The PCs must determine the reason for the string of murders and track down the perpetrator.

The Underdark is a subterranean wonderland, a vast and twisted labyrinth where fear reigns. It is the home of horrific monsters that have never seen the light of day. It is here that the dark elf Gromph Baenre, Archmage of Menzoberranzan, casts a foul spell meant to ignite a magical energy that suffuses the Underdark and tears open portals to the demonic Abyss. What steps through surprises even him, and from that moment on, the insanity that pervades the Underdark escalates and threatens to shake the Forgotten Realms to its foundations. Stop the madness before it consumes you! Note for DMs: This adventure is not for the faint of hearted, to run or to play. The module starts with 10 NPCs traveling with the party through the grueling Underdark. This number can grow. The encounters within the book are often incredibly deadly for the characters that would be going through it. This is because the module expects them to run or talk their way through the events, or, in some cases, the module expects them to lose. If your players aren't the kind of party to run, talk, or surrender, do not get this adventure. The module almost requires that you use milestone leveling because the experience provided does not commonly get players to the levels they should be once they get to certain milestones in the story (7th when they leave the underdark, 15th when they face the demon lords.) Good luck and happy questing.

Important: The adventure is 1e but it has monster conversion notes for D&D 4th edition The town of Highport, once a human community overlooking Wooly Bay from its perch on the northern coast of the Pomarj, fell prey to hordes of humanoids swarming out of the jungle-covered hills surrounding the settlement. Though the orcs, goblins, kobolds, ogres, and gnolls razed much of the place in their ferocious rampages, the smoldering ruins they left behind soon became a new kind of community, a place of trade between the humanoid “locals” and the unsavory human traders who have no compunction about doing business with them. Slaves are a commodity in ready supply in Highport’s market, since many pirates raid up and down the coast of the bay, putting fishing villages to the torch and filling their holds with captured refugees. Slavery has become a thriving business in the town, and rumors abound of a cartel of Slave Lords who run things from behind the scenes, filling their coffers in secret from the buying and selling of human chattel. The trade has become so prolific that the good folk to the north have grown tired of these depredations and decided to fight back. Forces of righteousness and honor have recently descended upon Highport, some openly and others in secret, in various attempts to destroy the machinations of the Slave Lords and abolish the abominable enterprise that has taken far too many loved ones from home and hearth. One such doughty servant of goodness is Mikaro Valasteen, a cleric of Trithereon. Mikaro slipped unnoticed past the crumbling walls of Highport with a single mission: to rescue and transport as many slaves to their freedom as possible. Mikaro and a handful of faithful assistants located a number of escaped slaves—as well as rescued a few more not sufficiently restrained and guarded—and shepherded them through the gates and beyond the reach of their humanoid tormentors, returning them to their lands and homes. This covert freedom brigade enjoyed remarkable success early on, since the servants of the Slave Lords were often lax in their vigilance and sloppy in their efforts to prevent loss of the “merchandise.” After one too many shipments never made its destination, the humanoids stepped up their security and the normal channels of escape from Highport closed to Mikaro and his team. He cannot risk exposure by smuggling the freed slaves through the gates as merchandise any longer, since shipments of goods are now regularly stopped and checked. No longer able to free the slaves in that manner, Mikaro began hiding his charges in an abandoned villa in a particularly rundown part of the town. Although they are safe for the moment, their numbers have grown unmanageable, and the priest fears it is only a matter of time before someone slips up and brings slavers to their doorstep. Ever more desperate to find a new means of escape from Highport, Mikaro has started work on a plan that is both daring and dangerous. He intends to use a series of old sewers coupled with natural caverns running beneath the town as an escape route to the sea beyond the walls. But he needs someone to clear out the creatures and pitfalls he knows lie within. Pgs. 2-27
