CelebriD&D with Joe Manganiello

CelebriD&D with Joe Manganiello is a special episode of Critical Role. It was confirmed to be at least semi-canonical when Joe Manganiello's character, Arkhan the Cruel, reconnected with Keyleth and Percival de Rolo in.

Synopsis
Tiamat, the Betrayer God and patron of chromatic dragons, sent visions of a locked-away loop of golden thorns and gems to her follower Arkhan in his dreams. Arkhan spent months of frustrating research seeking it out until finally coming across a monk of the Cobalt Soul named Duan who had the knowledge he needed. He hired a group of mercenaries—Keyleth, Percival de Rolo, the Headmistress, and Dupont Dupont—to help him delve into the Vault of Shumas in the Aggrad Mountains of Marquet.

After gaining entry, the party encountered and killed a few yuan-ti guarding the temple. Arkhan then barely took control of the undead caregiver there, and commanded her to show him to the artifact. She brought forth a manticore, who (following the caregiver's lead) willingly relinquished the loop—the Wreath of the Prism—on its neck. When Arkhan put the loop around his own neck, the thorns suddenly jutted deep into his neck and dealt him piercing damage, changed the appearance of his eyes, and changed his vision so that colors were more vibrant and he could see the heat of others' bodies. He then was able to command the manticore, on whose back the party flew from the temple, with the dominated caregiver following.
