The intrepid heroes, Vox Machina, find themselves facing the unexpected consequences of their defeat of the ancient blue dragon, Brimscythe. They are challenged to gather the tools and allies they need to meet this new threat.

Vox Machina travels to Vasselheim to search for allies, turning to a group of seedy bounty-hunters, called the Slayer's Take. They encounter a creature who holds information that could help them against the dragons of the Chroma Conclave.

Set upon retrieving a Vestige of Divergence hinted by the Sphinx, Vox Machina finds themselves at a lake. With the help of The Take, they uncover a temple filled with traps, enemies and a deadly sarcofage.

In a desperate bid to save a team member's life, Vax strikes a fateful deal with the Matron of Ravens, offering his life in exchange. As Vox Machina battles their way out of the sunken temple, Vax wonders what he's just signed up for.

While traveling to find the next Vestige of Divergence, Vox Machina passes by Pyrah, home to the Fire Ashari people. Discovering that the village is in distress, Vox Machina must help them, battling fire creatures that are spilling.

After escaping from the dragon Umbrasyl, Vox Machina is split up. Half of the party find themselves lost in the mysterious Fey Realm. Meanwhile, the other half of the party searches for a way to heal their cursed teammate.

Vox Machina finds the city of Syngorn and meets Vax/Vex's father. They search the Fey Realm for Fenthras Bow, facing ancient archfey. Meanwhile, Scanlan and Pike tend to Grog in Tal'Dorei.

Pike and Scanlan plan to get Titanstone Knuckles from Grog's uncle Kevdak in Westruun. Grog weak from the curse and haunted by his past with his uncle, questions if he's strong enough to face Kevdak.

Despite his weakened state, Grog confronts his uncle, Kevdak, for a fight to the death. The battle is intense, due to his uncle's Titanstone Knuckles, another Vestige of Divergence. Soon, the rest of Vox Machina arrive to join the fray.

While preparing to face the dreaded black dragon Umbrasyl, Vox Machina teams up with Grog's Herd, Scanlan learns a shocking truth about his past, while Vax reconciles with his new relationship with the Matron of Ravens.

As the black dragon Umbrasyl escapes their attempted ambush, Vox Machina pursues him to Gatshadow Mountain. In the fearsome acid-filled tunnels of Umbrasyl's lair, Vox Machina must make a final stand against the evil dragon.
