Upheaval of the Sword Coast
Wave Echo Cave
More than 500 years ago, clans of dwarves and gnomes made an agreement known as Phandelver’s Pact, by which they would share a rich mine in a cavern known as Wave Echo Cave. In addition to it’s mineral wealth, the mine contained great magical power. Human spellcasters allied themselves with the dwarves and gnomes to channel and bind that energy into the so-called Forge of Spells where magic items could be crafted.
Times were good and the nearby town of Phandalin prospered as well.
Then disaster struck as bands of orcs swept through the North and laid waste to all in their path. A powerful force of orcs and evil mercenary wizards attacked Wave Echo Cave to seize its riches and magic treasures.
Human wizards fought alongside dwarves and gnomes to defend the Forge of Spells and the ensuing spell battle destroyed much of the cavern. Only few survived the cave-ins and tremors, and the location of Wave Echo Cave was lost.
