Frenic reigns as the narrative's primary antagonist, commanding a cult of blood mages bent on destabilizing the Chantry's authority. Driven by the ambition to harness forbidden magic, he seeks dominion over powerful entities—most notably through capturing a High Dragon and twisting its might via blood rituals. Central to his scheme is Avexis, a young elven mage from the White Spire Circle of Magi, whom he coerces into consuming dragon blood to awaken her latent gift for commanding wild beasts.

He masterminds a conspiracy within the Chantry's ranks, colluding with corrupt allies like Knight-Commander Martel and Grand Cleric Callista. Their plot targets the assassination of Divine Beatrix III at a decade-spanning gathering, engineering a power vacuum for Callista's rise as Divine. Frenic further exploits Avexis' amplified powers, compelling her to summon and command a legion of dragons meant to ravage the Chantry's leadership.

In the climactic clash, Frenic's obsession with blood magic peaks as he betrays and sacrifices Callista, channeling her blood in a ritual that transforms him into a Pride demon. Though the metamorphosis grants godlike power, it seals his downfall when Avexis redirects the enslaved High Dragon against him, enabling Cassandra Pentaghast to strike the killing blow. Frenic's visage—marked by a glass eye, snaggletooth, and leather straps binding his face—enhances his aura of terror. His influence spans solely this narrative, absent from other documented franchise lore.
