Duke Inferno

Last updated 2026-09-10

"A cradle drowning in the delight of dreams, a haven for the cowardly."[4]

Duke Inferno, real name Ifrit, is a mission-exclusive NPC who serves as the antagonist of Trailblaze Continuance Mundane Troubles.

He was introduced in the Relic Set The Ashblazing Grand Duke, and first appeared in Myriad Celestia Trailer "A Night of Ever-Flame: Scene 33".

Profile

Duke Inferno is the leader of the Ever-Flame Mansion, a subfaction of the Annihilation Gang, and archenemy of the Jepella Brotherhood. He has three known children: Akash, Dubra, Caterina, with Constance having altered his memeories to make him believe she was his fourth.[8]

Appearance

Duke Inferno is a Fire Demon. He appears to have a skeletal, goat-like head, with a burning body and a monocle on his right eye. His outfit is seen in the Relic Set "The Ashblazing Grand Duke," including the Fetora crown, white gloves, a black robe, a black suit, a white shirt, a red necktie, and black and red boots.

History

Origin

At some point, Nanook destroyed a White Star named Fetora. The flames of the White Star coalesced with the power of Destruction to give birth to plasmic lifeforms.[9] According to Dr. Ratio, Duke Inferno, who hailed from Fetora, was born from Phase Flame,[10] which also supported rumors that the Genius Society member Sserkal had something to do with his creation.[11]

Obsessed with destruction and slaughter since birth, the embers left behind from the star's destruction were clasped in Duke Inferno's own hands, molded into the shape of Fetora's crown, and worn to the present day.[9]

Duke Inferno fancied himself as a conductor, and wore gloves to hold the conductor's baton covered in thorns. He orchestrated countless crises bent on annihilating lives. Duke Inferno believed that "the preciousness of something can only be appreciated in its eradication." He burned the historical and cultural items of the planet Lisalit, and after the end of a satisfying destruction, wiped the blood off his hands and donned pristine white gloves again, as if he was an aristocrat attending a banquet.[12]

Duke Inferno would admire his image in the mirror after an inhuman massacre. Although the ever-burning clan of fire demons see Nanook as their emperor and savior, the Aeon never glimpsed at them. Duke Inferno had never been able to grasp the essence of purity and believed the value of destruction lied in the value of the thing destroyed. While alive, Duke Inferno sought the gaze of Nanook.[13]

Ever-Flame Mansion

It is unclear when Duke Inferno founded the Ever-Flame Mansion, but it was Constance who stirred up the flames of his ambition, leading him to fall on the road of the Destruction.[14] Duke Inferno initially founded the Ever-Flame Mansion with his three children: Akash, Caterina, and Dubra. However, Constance, who was actually a former member of the Garden of Recollection, used her Cremator abilities to alter the memories of Duke Inferno, making him believe she had always been part of their family, as well as his most beloved and perfect daughter.[8]

After the fall of the Jepella Brotherhood due to the Stellaron Hunters, Duke Inferno grew stronger.[10][13]

Herta Space Station

Duke Inferno cast infernal fire into Herta Space Station to cause havoc by teleporting and disappearing those who were discontent with the station's leadership. His plan was foiled by the Trailblazer and Dr. Ratio, who had acquired a spark of the Phase Flame and used it to teleport those who had been kidnapped to safety.[10]

Penacony

The Ever-Flame mansion received an invitation to the Charmony Festival from Gallagher[15], and Duke Inferno wished to use the opportunity to destroy the planet.[16] However, before they could arrive, the Ever-Flame Mansion was attacked by Acheron, who wished to claim the music box invitation they had received so she could travel to Penacony herself. Acheron offered to spare Duke Inferno's life in exchange for the music box, but he chose to stick to his beliefs and fight her to the death even though his children fought to save his life, recognizing her as an Emanator.[2] After Duke Inferno's death, the Ever-Flame Mansion disbanded and parted ways, and Aventurine and Black Swan would later discover what Acheron had done,[11] and Constance still made her way to Penacony.[8]

Trivia

  • In the Xianzhou Luofu Skysplitter, the Northern Beggar will speak to the Trailblazer about Duke Inferno, referring to him as the "Southern Emperor," and describing him as having "ram's horn on top of their head, wearing a monocle, donning a crown of fire, draped in an elegant robe, alabaster-white gloves, and very expensive boots... topped off with the daunting aura of a powerful warrior."
    • In subsequent interactions, the Northern Beggar will state that they hoped to meet after he "after some banquet" (referring to the Charmony Festival), with the Trailblazer eventually revealing Duke Inferno's death by showing the Northern Beggar the "The Ashblazing Grand Duke" relic set.
  • According to Akash, Duke Inferno does not eat mutton.[17]
