In ages past, the wizard Karavakos made a deal with devils, which resulted in him being trapped in an extradimensional pyramid, unable to escape.

Although set to allow PCs to just fight through each encounter, tips are included for PCs negotiating with the factions trapped in the pyramid.

However, the city’s vibrant beauty is overshadowed by a mysterious scourge that plagues all within the land. Can the divergent forces within the city discover the truth before all are overcome by this growing threat? Five Four-Hour Mini-Adventures for 1st-4th Level Characters

"More than five hundred years ago, clans of dwarves and gnomes made an agreement known as the Phandelver’s Pact, by which they would share a rich mine in a wondrous cavern known as Wave Echo Cave. In addition to its mineral wealth, the mine contained great magical power. Human spellcasters allied themselves with the dwarves and gnomes to channel and bind that energy into a great forge (called the Forge of Spells), where magic items could be crafted. Times were good, and the nearby human town of Phandalin (pronounced fan-duh-lin) prospered as well. But then disaster struck when orcs swept through the North and laid waste to all in their path. A powerful force of orcs reinforced by evil mercenary wizards attacked wave echo cave to seize its riches and magic treasures. Human wizards fought alongside their dwarf and gnome allies to defend the Forge of Spells, and the ensuing spell battle destroyed much of the cavern. Few survived the cave-ins and tremors, and the location of Wave Echo Cave was lost. For centuries, rumours of buried riches have attracted treasure seekers and opportunists to the area around Phandalin, but no one has ever succeeded in locating the lost mine. In recent years, people have resettled the area. Phandalin is now a rough-and-tumble frontier town. More important, the Rockseeker brothers - a trio of dwarves - have discovered the entrance to Wave Echo Cave, and they intend to reopen the mines. Unfortunately for the Rockseekers, they are not the only ones interested in Wave Echo Cave. A mysterious villain known as the Black Spider controls a network of bandit gangs and goblin tribes in the area, and his agents have followed the Rockseekers to their prize. Now the Black Spider wants Wave Echo Cave for himself, and he is taking steps to make sure no one else knows where it is." Extra Info from AL.com users: by @marcellarius. "There are a variety of locations in this adventure: the town of Phandalin, a gang hideout, a ruined keep in the forest, a destroyed village, and Wave Echo Cave (a dungeon crawl). The adventure is written in a sandbox style and relies on the players to choose their path. Phandalin offers several side-quests which could serve as hooks for continuing adventures. The premade characters have ties in their backgrounds to NPCs and locations. If you're not using these you'll need to consider other ways to introduce key NPCs."

Beneath the jungle-covered ruins of an ancient human temple lies a small outpost of grell that have taken to hunting the nearby area by night.

Pgs. 115-120

Temple of the Gleaming Sands is a short adventure for four 5th-level characters that features monsters, spells, and items from the newly released Sandstorm book. You can use this scenario to introduce the new material on deserts and arid wastelands into your campaign, or you can just use it as a site-based adventure in a desert area. The scenario is set in a remote area of the desert that very few humanoid travelers visit. The temple from which the adventure takes its name has lain forgotten for centuries and is now inhabited only by monsters who use it as a base. The area around the temple should be inhospitable enough to discourage humanoid settlement.

They also learn that many different agencies are interested in this relic, including those loyal to the various House Cannith elders and agents of the infamous Lord of Blades. Pgs. 307 - 317

Something is killing people in Palebank Village, and if the party does not stop it they could be next.

Trouble Cubed is a is a pseudo-adventure with three interesting gelatinous cube encounters. These three encounters are structured in a way that they can be used together as one adventure, or each individually dropped into any adventure from EL5 to 7. The encounters vary the cube's encounter situation significantly, and the tactics needed to deal with them, such as by trapping a character with a portcullis between a cube and a pit trap, placing a cube half down a pit trap, and having the cube accidentally ingest a beneficial potion (such as spider climb). Pgs. 29-30

Mykon Drift, genius inventor and entrepreneur, has disappeared on the eve of his greatest ever product launch, and nobody seems to know why or where he’s gone. Certain jaded onlookers might think this is for the best, for Drift is a disrupter in the truest sense, and the technomantic marvels he creates often wreak havoc on the guilds and economies of the Sword Coast. But titans of industry like Mykon Drift don’t just disappear for no reason, and his most loyal apprentice is willing to pay to find him. Unfortunately, that apprentice isn’t willing to pay very well, so what they get is the Grib-bits Detective Agency. "The Gribbits Detective Agency Part II" is a Dungeons & Dragons adventure for four 2nd-level characters. It is designed to follow on from "The Gribbits Detective Agency", and should be played in a single sitting.

Long unoccupied, the pyramid on Sorcerer’s Isle now flows with strange magical energy, warping creatures and the landscape around it.

Long ago, a local priest created a warded graveyard on a remote hillside. As the years passed, it gained a reputation as a spot whose defenses were powerful enough to keep undead in and tomb robbers out. Adventurers began to bring the remains of any creatures they suspected might become restless in death to the Tomb Steppe for interment, and in time they also sought aid against such creatures from the friendly priest. After his death, a brief spate of undead activity commenced, then died away once again. As the years passed, the tales of undead activity in the Tomb Steppe faded into legend, and colonists began to move into the lands nearby. The town of Night Falls was founded a short distance from the graveyard, and it grew quickly into a thriving trade center and farming community. Realizing that the Tomb Steppe was safe enough during the day, the citizens began burying their dead there rather than building new crypts on pristine farmland. Because this method of interment was cheap and easy, people from many surrounding communities brought their dead to the town as well. The business of burial brought new prosperity to Night Falls, and a guild called the Funerary House sprang up to control the trade. But it seems that the threat from the Tomb Steppe has not entirely been laid to rest. The Great Mausoleum -- the largest and finest tomb in the steppe, has been unsealed, and an apparition has been seen within. Who will go to the Tomb Steppe by night and reseal the tomb? Lest Darkness Rise is a short adventure for four 7th-level characters. In keeping with the season, it has a stronger horror theme than most D&D adventures. This scenario can be used as the climax of a series of adventures featuring its secondary characters, or it can simply be a site-based adventure that the PCs stumble across at the right moment. The scenario is set in a semi-civilized area in the far north, far from cities and churches, where winters are harsh and summers never get very hot. These inhospitable conditions have resulted in a low humanoid population. The scenario need not be set in such a wilderness; a rural farming community far from cities works just as well. The only real requirement is that the area have few settlements. The action takes place in the small town of Night Falls and a nearby necropolis of tombs, mausoleums, and graves known as the Tomb Steppe. As always, feel free to adapt the material presented here as you see fit to make it work with your campaign.

(NB: this adventure is set in a desert in the broader 'Nentir Vale' world, but not the Nentir Vale itself) Eladrin raiders led by the Half-Elf Emrett Mazrid have been trying to uncover the secrets of immortality.
