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 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.

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.

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.

In disguise, Raishan visits Vox Machina with a promise of aid. She tells them of a vestige capable of defeating Thordak; the Plate of the Dawnmartyr. The team is divided on trusting the duplicitous dragon, but journeys to the city of Marquet to test if she speaks true.

Go to hell, Vox Machina! But stop in Draconia first. Don't worry - Kima and Allura know someone there who can help. You'll love her, she's great. But first, don't forget romance. Percy has feelings for Vex, Vax has feelings for Keyleth! What could go wrong?

As Kima is hunted by Vorugal, Allura struggles to stop the beast and save her love. Meanwhile in hell, Pike gambles against a devil for the souls of her friends and the future of the world. Does she have an ace up her sleeve that can save the day?

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.
