Aside from the delightful fan service that this theory entails, it also makes plenty of sense within the “Critical Role” universe, as every member of the Vox Machina crew has a good deal of history with the divine beings of Exandria.
Not only were they instrumental in defeating Vecna, The Whispered One, after he ascended to godhood, but throughout “Critical Role,” we’ve seen them serve the interests of important deities like Ioun, Pelor, The Raven Queen, and Sarenrae. Suffice it to say, the members of Vox Machina are incredibly important to the deities of Exandria, making them prime candidates to ascend to godhood should any of those deific thrones go vacant.
U/UndopeMonk went on to clarify which members of Vox Machina would take over for which god. The easiest to predict are Pike Trickfoot (Ashley Johnson), who serves as the champion of Sarenrae the Everlight, and Vax’ildan (Liam O’Brien), who serves as the champion of the Raven Queen. Both of these legendary adventurers should have no issue taking over for their respective gods. The Redditor also speculated that Grog Strongjaw (Travis Willingham) would become the god of “War, Rage, Destruction, and Family,” asserted that Keyleth (Marisha Ray) is already practically a god in her own right, and that Percival de Rolo (Taliesin Jeffe) would descend to become the lord of Hell. Though U/UndopeMonk was a bit fuzzy on where the other party members would fit into the new pantheon, it’s clear that this theory has some real substance behind it and, if accurate, would allow Campaign 3 to come full circle and wrap up the whole “Critical Role” storyline.
