Vox Machina travels to the mysterious ancient city of Vasselheim to search for allies. They're soon forced to turn to a group of seedy bounty-hunters, called the Slayer's Take. There they encounter an ancient creature who holds critical information that could help them in their fight against the dragons of the Chroma Conclave.

Upon arriving at the location of the next Vestige of Divergence, Vox Machina must face the challenges of the mysterious sphinx, Kamaljiori – the mate of Osysa. But even if they can succeed, a new, unexpected threat lies waiting for them.
