Phandelve's Pact

In Glasstaff's laboratory you found a journal of an adventurer named Urmon.
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 ores swept through the North and laid waste to all in their path. A powerful force of ores 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, rumors 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.
Urmon records that a magic mace named Lightbritiger was commissioned by priests of Lathander, the god of dawn, from the rnages working with the gnomes and dwarves of the Phandelver's Pact. The mace was lost when Wave Echo Cave and its mine vanished from history.
