Vizeran is still chanting, though the cadence and intensity have altered now. Seftan realizes at the last moment what has changed. Vizeran, with a smirk, disappears from the area, leaving you alone here to watch the demons fight.
The fights among the lesser demons is impressive enough, but the battle between the demon lords is something else entirely. Their roars make the cavern shake, dust shaking down onto your heads, and missed attacks gouge chunks out of the stone walls.
The sounds of battle finally die away, the ground before you stained black and red with demonic blood and ichor. In the terrible grip of Demogorgon, even the mighty Orcus looks almost small. Tentacles hold the Demon Prince of Undeath in a crushing grip, slithering across the maggot-riddled flesh of the horned demon, as they tighten inexorably. A strangled gasp issues from the demon lord's throat as a horrific crunching sound echoes throughout the cavern and his skull-topped wand clatters onto the floor.
Demogorgon casts aside the limp form, which melts away as Orcus returns to the Abyss that spawned him. The Prince of Demons throws back his two heads and roars his triumph. As he does, his nearer head turns, burning eyes raking across the battlefield. Filled with bloodlust and battle rage, the demon lord searches for another target.
You realize with horror that he's a mere 80 feet from you now. The horror of the battle rooted you in place as he drifted close throughout.
