The Phandelver Pact

Over half a millennium ago, clans of both dwarves and gnomes made an agreement, one that allowed both species to share a bountiful location known as Wave Echo Cave. Along with it's mineral wealth, it also came with a trove of magical power, one that enticed Human spellcasters into wishing to join the alliance between the Gnomes and Dwarves. In doing so, the used the caves innate magic to further their own magical power and understanding.

However, all came to a close one day. A large-scale battle broke out within the cave, leaving the Phandelver Alliance left crawling from the rubble and Wave Echo Cave forever wiped from any future map.

This changes with the Rockseeker brothers - a trio of dwarves - who have discovered Wave Echo Cave and wish to unlock it's secrets lost to time.
