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.

Despite his weakened state, Grog confronts his uncle, Kevdak, in a fight to the death. The battle is intense, with Grog taking a beating at the hands of his uncle’s Titanstone Knuckles, another Vestige of Divergence. As Grog is about to fall, the rest of Vox Machina arrives, just in time to join the fray.

After a devastating loss, Vox Machina must take the fight to Thordak with one less memeber. They travel across Exandria recruiting allies to face down the Cinder King in his lair. Will the gathered might of the world be enough? Or will Thordak turn Tal'Dorei to ash?

Thordak strikes back! The combined armies of Whitestone and Syngorn are in trouble as the dragon's ambush is sprung. Betrayed by Raishan and left with nowhere to run, Vox Machina scrambles to find a new plan before their allies are wiped out.
