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.

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.

Vox Machina explores an ancient temple to search for their first Vestige of Divergence, a legendary weapon they hope will aid them against the dragons of the Chroma Conclave. As they overcome a series of dangerous encounters to reach the sunken tomb, one of the team makes a terrible mistake.

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 out into the world through a portal to another dimension. As they try to close the portal, Keyleth learns more about the power that lies within her.

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.

After escaping from the black dragon Umbrasyl, Vox Machina is split up. Half of the party find themselves lost in another dimension, the mysterious Fey Realm. They encounter strange dangers as they seek to recover the next Vestige of Divergence. Meanwhile, the other half of the party searches for a way to heal their cursed teammate.

In the Fey Realm, Vox Machina unexpectedly discovers the city of Syngorn and meets Vax and Vex's father. After the emotional encounter, Vox Machina journeys deeper into the Fey Realm, searching for the next Vestige of Divergence - the Fenthras Bow. To acquire it, they must confront an ancient and powerful archfey. Meanwhile back in Tal'dorei, Scanlan and Pike attempt to nurse Grog back to health.

Knowing that the Titanstone Knuckles are in the city of Westruun, Pike and Scanlan come up with a plan to get them from their current owner, Grog's uncle, Kevdak. But Grog, weakened by Craven Edge's curse and haunted by his last encounter with his uncle, questions whether he is strong enough of mind, or body, to confront Kevdak.

Despite his weakened state, Grog confronts his uncle, Kevdak, in a fight to the passing. 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.

While Scanlan makes a fateful and shocking discovery about his past, Vax confronts the Matron of Ravens to uncover the truth about the mysterious pact he made with her. At the same time, Vox Machina teams up with Grog's Herd and sets their sights on Umbrasyl, preparing an ambush to take down the dreaded black dragon.

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.
