The Sunken Tomb

is the sixth episode of the fourth chapter of Critical Role. In hopes of defeating the Chroma Conclave, Vox Machina sets out to recover the Vestiges of the Divergence—ancient armor, weapons, and other items of immense power. They learn the location of one Vestige, the Deathwalker's Ward, interred with an ancient Champion of the Raven Queen... at the bottom of a lake.

Continuity
The regular episode for 2016-02-25 was replaced due to cast illnesses and attendance at a funeral, airing instead.

The regular episode for 2016-03-03 was cancelled due to Matthew Mercer and Marisha Ray being in Ireland for Kaizoku-Con.

This episode celebrates the one-year anniversary of Critical Role, which is 2016-03-12.

Previously on Critical Role
"Vox Machina, our intrepid band of adventurers, after dealing with the horrible attacks by the dragon circle known as the Chroma Conclave destroying cities all across Tal'Dorei, the party escaped, sent the refugees they could, as well as allies, back to Whitestone—seemingly not on the radar of this attacking front of dragons at the moment. They made their way toward Vasselheim to find allies, Pike staying behind to help with the refugees at the moment.

"Upon going to Vasselheim, [they] managed to encounter a number of old friends from the Slayer's Take and enlist them for the time being to help [them] with the refugees and [their] current wanderings in the city proper. At the same time, [they] encountered Lady Kima, who also has agreed to help with the events in Whitestone and this entire dragon attack towards the east. After wandering the city for a bit and retrieving these allies, [they] followed Grog into the Trial Forge, where [he] had a conversation with Earthbreaker Groon—and by conversation I mean a full-on, drag-out sandpit battle to prove [his] worth to him. In which case [he] was given information about these things called the Vestiges of the Divergence—artifacts of great legendary power that existed from previous wars that had wiped out most of society multiple times. These Vestiges have been scattered around the world, many of them lost to the history books, or passed down as symbols of power through various bloodlines or government positions, or stolen and haven't been seen for hundreds of years.

"[The party] found the location of two of them: one of which was the Titanstone Knuckles, and the other happened to be some sort of leather, the Deathwalker's Ward that belonged to a Champion of the Raven Queen. This exists in, apparently, the Champion's tomb, which used to exist to the west of Vasselheim, until it eventually sunk into the ground as the topography shifted over time, and resides beneath a lake known as the Marrowglade Loch."
