Base creature: Ancient Red Dragon (CR 24) This colossal ancient red dragon, a legendary commander of immense power, coils atop a volcanic peak, its scales shimmering with the heat of a thousand forging fires. Its eyes glow with an infernal intelligence, and a plume of smoke constantly billows from its nostrils. A faint, arcane aura of scorching heat visibly distorts the air around it, and molten rock flows freely in its immediate vicinity, controlled by its immense will.
