The ragtag group of adventurers known as Vox Machina are commissioned by Sovereign Uriel to find out who (or what) is decimating villages in the outskirts of Emon.

Vox Machina's victorious return home to Emon is cut short by the arrival of ancient dragons, the Chroma Conclave. Despite Vox Machina's best efforts, the dragons lay waste to the city, forcing the team to find a way to escape.
