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.

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 journeys to Whitestone to confront the Briarwoods and help Percy reclaim his family home. As they travel, Scanlan studies Delilah Briarwood’s mysterious spell book to uncover clues. But the team’s first road trip is interrupted when the Briarwoods send horrific monsters to retrieve their missing book.

Vox Machina finds Whitestone's holy leader, Keeper Yennen, who tells them of a growing rebellion. The team realizes that to defeat the Briarwoods they will need the help of rebel leader, Archibald Desnay. But first they must stage a daring prison break and confront the Briarwoods’ sadistic jailer, Kerrion Stonefell.
