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'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 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.

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.
