The Volcanic Oracle

Appearance
The Volcanic Oracle is a twisted, soot-stained giantfolk shaman whose eyes glow with the intense, orange light of internal magma. His skin is cracked like cooling lava, and steam constantly vents from his nostrils and ears. He wears robes of woven asbestos fibers adorned with shards of volcanic glass.
Personality
Cryptic, delusional, and prone to violent outbursts, the Oracle speaks in fragmented metaphors about the "Heartbeat of the Mountain." He believes himself to be the chosen voice of Ignis-Kaan and views all who oppose the World-Fire as ash to be scattered.
Secret Motives
The Oracle is the primary psychic conduit for the slumbering dragon Ignis-Kaan. His "prophecies" are actually the dragon's tactical commands, filtered through his own madness. He is a living puppet, and his very existence is tied to the dragon's eventual awakening.
Combat Tactics
The Oracle channels primal volcanic energy to create geysers of lava and blinding clouds of toxic ash. He can foresee the party's movements through his connection to the dragon, granting him a high AC and advantage on saving throws. He can summon Magma Elementals to protect him while he conducts world-shaking rituals.
