From pyro- + -mancy.

Why this word is great

PYROMANCY — [Noun] Divination by fire or the magical control of flame. From the Greek pyro- ("fire") and -mancy ("divination"). Unlike "pyrokinesis" (which reduces fire to mere psychic manipulation) or "augury" (which scatters its divinations across birds and omens), pyromancy is fire’s oldest conversation—its flickering tongues whispering prophecies in the dark. It is the hypnotic dance of flames in a midnight bonfire, the way embers collapse into cryptic sigils, the sudden flare that illuminates a face long forgotten. Fire does not lie; it only burns away everything but the truth.

noun

Divination by fire; the use of fire to supernaturally gain information.
The magical power of conjuring or controlling fire.
