Lost Mines of Phandelver
Five hundred years ago, 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. Times were good, and the nearby human town of Phandelver 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 the evil mercenary wizards attacked the 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.
