"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 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."

THE NEXT MARCH WASN'T DUE FOR ANOTHER 189 YEARS. TRY TELLING THAT TO THE MODRONS! On a regular schedule, the Great Modron March spills out of Mechanus, and the lawful automatons files their way around the Great Ring. No one knows why they do it, but everyone stays out of their way - because when the modrons march, they'll walk right over a berk who doesn't know enough to move aside. But this March has started decades before it was supposed to begin, and that's even more of a mystery. Caught unprepared, the planes shudder under the modrons' collective footsteps - and even the modrons themselves seem a little out of sorts. The Great Modron March anthology features 11 adventures for characters ranging from 1st to 10th level, as well as new information about the modrons of Mechanus. Each adventure can be played separely or linked together to form an extended campaign. The modron procession touches every Outer Plane in turn - and it isn't always welcome. On their unswerving path, the clockwork creatures will destroy celestial towns, be attacked by evil knights intent on using modron parts in foul experiments, and lead characters onto the deadly plains of the Abyss and into the famous prime-material labyrinth of Undermountain. Without help, they'll be lost in the swirling chaos of Limbo or even fail to complete the March entirely. And along their route, every blood on the planes seeks the answer to the most important question: Why have the Modrons abandoned their normal, lawful schedule to march years before they're due?
