In the midst of battle against Vox Machina and the Herd of Storms, the ancient black dragon Umbrasyl retreats to Gatshadow Mountain after sustaining heavy damage. With Scanlan Shorthalt and Vax'ildan trapped inside the dragon and Grog Strongjaw hanging from a chain attached to an axe embedded in Umbrasyl's scaled flesh, the party must somehow survive and choose whether to follow the dragon into its lair or wait for another opportunity to slay it later.

As the citizens of Westruun learn of Umbrasyl's demise, they must decide whether to flee possible retaliation from the Chroma Conclave or reclaim their city. With the burden of so many lives and so much destruction, the members of Vox Machina struggle with their own responsibilities and destinies. Perhaps a humble paladin can restore the hope of frightened citizens and powerful heroes alike...
