The Sword Coast Legends
Wave Echo Cave
15 miles east of Phandalin, at the base of the Sword Mountains.
More than 500 years ago, clans of dwarves and gnomes made an agreement known as the Phandelver’s Pact, by which they would share in the riches of the wondrous cavern of Wave Echo Cave. In addition to its mineral wealth, the cave contains great magical power. Human spellcasters allied themselves with the dwarves and gnomes to channel and bind that energy into a great forge (known as the Forge of Spells), where magic items could be crafted. Times were good, and the nearby town of Phandalin prospered as well.
Disaster soon struck. Orcs swept through the North and laid waste to all in their path. A powerful force of these 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 battle destroyed much of the cavern. Few survived the cave-ins and tremors, and the location of Wave Echo Cave was lost.
In the centuries since, countless prospectors and adventurers searched for the lost mine, but none succeeded until the Rockseeker Brothers found the entrance in recent months. Unfortunately, the Rockseekers had been tracked by spies working for Nezznar, The Black Spider, and they inadvertently led the drow to their prize.
Nezznar and his followers dealt with the two Rockseekers who were guarding their find. He then took up residence in the cave, seeking to gain access to the still guarded Forge of Spells. It was then that Quick Ben, Tallguy McClean-Shaven, and Rusty Blades arrived. In the ensuing battle, Nezznar triggered a collapse of the cave, which furthered destroyed several rooms in the cavern. Nezznar was caught in his own trap and killed. The Forge of Spells was rediscovered by the adventurers, and turned over safely to the remaining Rockseeker Brothers, who have begun the work of clearing the cave of debris, and preparing it for mining once more.
