The ragtag group of adventurers known as Vox Machina are commissioned by Sovereign Uriel to find out who (or what) is decimating villages in the outskirts of Emon.

Vox Machina tells Sovereign Uriel of the monstrous culprit behind the devastating village attacks, and manage to track the creature back to its hidden lair. For the safety of Emon, Vox Machina must rise to the occasion and go face-to-face with a beast that is seemingly impossible to kill.

Vox Machina is invited to the palace for a formal dinner, where Percy encounters murderous figures from his past: the mysterious Lord Sylas and Lady Delilah Briarwood. While gathering more information about the Briarwoods, a battle ensues. In the aftermath, the team discovers Percy’s tortured past has left something dark brewing inside of him.

After ruining Sovereign Uriel’s diplomatic dinner, Vox Machina is confined to their Keep under house arrest. While they stave off boredom, Keyleth convinces Percy to open up about his dark history and Pike fears she has lost her connection to her deity. Meanwhile, a looming new threat is on its way to confront Vox Machina.

Vox Machina has stopped the Briarwoods’ evil ritual, but at a heavy cost. As they flee the Ziggurat to save one of their own, Percy is eager to take revenge on their prisoner, Delilah Briarwood. When Vex implores him to let go of his vengeance, Percy must confront the darkness within himself.

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.

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.
