Varian; The Radio Demon

"Decades ago, Varian manifested in Hell, seemingly overnight. He began to topple over lords that had been dominate for centuries. That kind of Raw power had never been harnessed from a mortal soul before, then he broadcast his power all throughout Hell, just so everyone can witness his ability. Sinners started calling him the radio demon. As lazy as that is, many have speculated what unimaginable forces enabled him to rival our world most ancient and destructive evils."

Varian gets sent to Hell because Rapunzel and Eugene were stupid and tried to someone a demon from Hell, but it backfired and sucked Varian into Hell. He rotted there for 8 months but it Hell it was more like 80 years. He's pissed. He wants revenge. He's mostly mad because he warned them that this will go south. Also, this book design will be different there will be a lot of flashbacks to how he lived in hell and how he got his power.
