Purvan Suul

 was a follower of the Raven Queen. After ritualistically giving his name to the Raven Queen when he swore himself to her service, Purvan Suul was simply called "The Champion" by the people. As an NPC, his corpse is played by Matthew Mercer.

Looted by Vox Machina
The Champion was interred with his powerfully enchanted armor, known as the Deathwalker's Ward, which was actually one of the Vestiges of the Divergence. In, Vox Machina found and recovered the Champion's Vestige with the aid of Kashaw Vesh and Zahra Hydris.

Vox Machina also looted the Champion's enchanted pendant, Raven's Slumber, which at the time contained his wolf ally, Galdric.

Purvan's tomb was protected by a necromantic trap which killed Vex'ahlia when it was triggered by Percival.
