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.

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?

After a devastating loss, Vox Machina must take the fight to Thordak with one less memeber. They travel across Exandria recruiting allies to face down the Cinder King in his lair. Will the gathered might of the world be enough? Or will Thordak turn Tal'Dorei to ash?
