Into the Frostweald

is the tenth episode of the fourth chapter of Critical Role. Vox Machina continues the quest to collect the Vestiges of the Divergence in order to defeat the Chroma Conclave. Along the way, they are rejoined by Pike Trickfoot and discover some other old friends in dire straits.

Recap
"The adventuring party of Vox Machina, traversing the lands in search of lost artifacts of wars of old, referred to as the Vestiges of the Divergence, in hopes of eventually tearing down and defeating a conclave of chromatic dragons called the Chroma Conclave that have destroyed society all across the continent of Tal'Dorei and beyond. They returned to the outskirts of a city named Westruun that was very important in their early adventures, to find it—from a distance—partially destroyed by the dragon attack but a couple weeks before, and since taken over by what seems to be the remnants—now swelling in power and size—of Grog's old herd of wandering barbarians and various savages.

"Having taken the city by force and ruling it with an iron hand, it was also deemed not the right time to face this foe, and as such the party continued venturing southward in the direction of the Frostweald, where, somewhere at the base of the Stormcrest Mountains, the mate of Osysa—the gynosphinx they had met in Vasselheim—her mate resides somewhere in this vicinity. That's all the information they have to go on as they head down towards the frozen forest."
