Inspired by the campaigns featured in the Critical Role podcast, this adventure takes place in the land of Exandria, with players tasked with uncovering the secret behind an ancient underwater realm known as the Netherdeep. The campaign itself is designed to take characters from Level 3-12 and also explores a large area of the continent of Wildemount.

Your PCs are reaching the upper end of the heroic tier. New worlds are opening up to them—they might have already ventured to the Feywild, for example, and made contacts with inhabitants of that magical plane. Now they are ready to take their first steps into the darkness. The Shadowfell awaits... Vandariel, a shadar-kai witch who calls herself the Voice of Pain, is a fanatic devotee of the Raven Queen. She has founded and become the self-proclaimed high priest of a bizarre cult, the Lords of Pain, whose purpose is to bring more fey into the shadow pact with that goddess of death. Although the original shadar-kai entered this pact voluntarily, and the race breeds true, Vandariel is consumed by what she sees as a divine mission to reveal the mystery to all fey—whether they wish it or not. Those who do not come voluntarily to the truth are brought against their will. Dark stalkers move like the night, seeking out and abducting suitable subjects. This Side Trek can serve as an introduction to the dangers of the shadow realm. It works well for PCs who are approaching the paragon tier, since it presents a reasonable challenge for characters of 10th level. It is suitable as a climactic encounter for lowerlevel adventurers, as well. It consists of only two encounters.

Kingdom of the Blind is a short adventure for four 8th-level characters. The adventure is set in a minor duchy that is fairly removed from the ruler of the land. As a result, trouble can brew in the land and the king would not know immediately. The PCs have just learned that Dephyl is alive and well and ordering blocks of granite. Meanwhile, Zhanna and Dephyl are on the third floor. If the PCs encountered the animated staircases on the first floor, the shriekers on the second floor, or triggered the trap outside Dephyl's study, the couple knows someone unwelcome is downstairs and moving up. They begin to prepare for their arrival.

A famous relic hunter seeks adventurers to help her find caches of treasure hidden by the now-defeated followers of the Cult of the Dragon. Her maps and notes may lead the way to great wealth—or a terrible death. And do other parties have designs on the treasure as well?

When the priestess of Ehlonna was murdered by a werewolf, the townsfolk of Deepwood lost no time in meting out justice, even though the shapechanger turned out to be a trusted friend and neighbor. But his journal has the town worried. Written in an unknown tongue, it seems to contain important pieces of information. Is it a list of other werewolves? Is the threat to Deepwood over, or has it only just begun? Cries of "Murder!" brought the villagers of Deepwood running to the temple to witness a grisly sight. The priestess of the Temple of Ehlonna lay murdered on the floor, savaged by some vicious beast. Above her body stood a large wolf. Then, before their horrified eyes, the wolf turned into a man -- their friend and neighbor Trammil! The villagers lost no time in giving Trammil the justice he deserved at the end of a rope, even over the objections of those few who thought he deserved a trial. But Trammil's death has not made the villagers feel safe. No one suspected his dark secret until the day of the crime. Could there be others? Can anyone in town be trusted? Only someone who can translate Trammil's journal and fully investigate the murder can solve the mystery.

Jelendra, a tulani of summer, has gathered a small following of dark fey creatures to help her get revenge against the Highridge Arcane eladrin elders. When they had the nerve to question her interest (they called it “obsession”) in the destructive power of the Wild Hunt, Jelendra flew into a rage and stormed out of the Highridge Arcane. Now, she controls a fane to an ancient spirit of the Wild Hunt. Not knowing what became of her, the elders ask the adventurers to find Jelendra. “Let her know that she is missed, and we want her to return home,” one elder says. Pgs. 114-119

The citizens of Phent, which is a large town in Thesk, are a proud, yet warm and accepting folk. For the past nine years, they have been host to over six hundred orcs, which is certainly an anomaly in the average Faerûnian community. In 1360 DR, Zhentil Keep sent one thousand orcs to aid in the fight against the westward-sweeping Tuigan hordes. The orcs fought well—well enough that the citizens of Thesk welcomed them as citizens when Zhentil Keep abandoned them in this land in 1363 DR. Still, a current of unsettling concern lingers. Some believe that the orcs are still part of Zhentil Keep’s strike force, but that they went on standby to wait for the moment when their masters give the signal. Once allowed, these orcs may launch a crippling attack from within. However, in nine years, no signal has been given—at least none that any of the paranoid folk have noticed. The orcs are enthusiastic citizens and, apart from some rowdiness during breaks from the mines or fields, they have hurt no one. And then, a prophet comes, with a message of war . . . In A Call to Arms, the player characters (PCs) have a chance to prevent orcs from rising up against some humans. This adventure is designed for four 9th-level D&D® characters. The encounters can be adjusted up or down to suit your group’s needs, however.

The time is now! The yuan-ti lay on the cusp of freeing an ancient being of insurmountable evil from its imprisonment. Should this happen, Faerûn may very well be plunged into an age of darkness. You have traveled the width and breadth of the peninsula and learned what you could about your foe. Now it’s time to put that knowledge to use. Steel yourself, adventurer, there are important deeds to be done! A Four-Hour Adventure for 11th-16th Level Characters

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.

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. In the first episode, the PCs were employed by Duke Ambrinigan to exchange a ransom of 10,000 gp in gems for a golden lion that was taken by frost giants in a recent raid. While waiting for the giants to arrive at the designated meeting place, the PCs watched as the white dragon Whildenstrank attacked the giants and then flew off with the statue. Charged with returning the golden lion statue at all costs, the PCs move to investigate the site of the battle.

The PCs intervene in an attempted murder and are hired to find out what made a guy go mad. This leads them to search for Yenejg Togan's tower/a strange merchant in the nearby forest, where they discover that bugbears have moved in. After exploring the tower, finding the "merchant", and dealing with the bugbears and the lamia that caused the incident in the first place, they were still unable to get into Yenejg's inner sanctum without a key. The PCs return with the key and figure out how to use it to enter Yenejg's sanctum. They then explore it, dealing mostly with traps, and finally discover the resting place of the treasure Yenejg stole from the town. This adventure begins with a skill-based roof-top chase and can include some complex non-combat interactions with potentially hostile NPCs. It includes some semi-interesting traps as well as some nifty puzzles. No villain to speak of. Fool-hardy adventurers can get themselves killed, but some caution will result in only one extremely hard fight, and even that can be avoided if action is taken quickly. Pgs. 74-107

The PCs have traveled to the Nine Hells to confront an outpost of devils responsible for slave raids on their homeland. In this realm of burning ash and fire-streaked skies, the infernal legions prepare constantly for war. Pgs. 138-143

In “Rescue at Rivenroar,” the player characters must brave the depths of ancient catacombs in search of prisoners taken from the town of Brindol in a midnight raid. The hobgoblins, bandits that style themselves after an invading horde from long ago, have taken refuge in a dungeon under a ruined mountain fortress, and the PCs must clear them out to find the captive townsfolk and the treasures taken from Brindol. “Rescue at Rivenroar” also marks the first step in a great journey - the Scales of War Adventure Path, which spans 30 levels and put the PCs at the crux of events that shapes the world for centuries to come. While the scope of this adventure isn’t as grand, it represents the seed from which an epic tale will surely grow. Pgs. 4-45

The isolated tower of the wizard Deros Frist is an example of a typical tsochari incursion into the human world. This short adventure site describes the lair of a tsochar noble that has successfully replaced Frist, a local wizard of some renown.

In ages past, the wizard Karavakos made a deal with devils, which resulted in him being trapped in an extradimensional pyramid, unable to escape. His only hope for escape is to lure adventurers into the Pyramid, in hopes that they will destroy his splinters and return his power to him. But his wife Vyrellis, whom he slew in a rage when the Pyramid formed, still lingers in spirit and wants nothing more than to see him laid low... Although set to allow PCs to just fight through each encounter, tips are included for PCs negotiating with the factions trapped in the pyramid.
