Gallû (gallu)

The provided material does not supply a primary mythic origin narrative for the gallû; the sole explicit ancient‑world attestation in the supplied sources identifies gallû/gallu as demons or devils belonging to the ancient Mesopotamian Underworld. Modern role‑playing and fantasy sources appropriate the name and place such beings as denizens of or agents from the Underworld, but those are creative adaptations rather than preserved ancient origin accounts.

No detailed, verifiable physical description from Sumerian or other ancient Mesopotamian primary texts is provided in the supplied sources. Contemporary fantasy sources (cited in the materials) portray adapted versions as large, often faceless or terrifying creatures (e.g., Planescape/Pathfinder treatments), but those depictions are modern fictionalizations and not attested in the ancient material supplied.

The only ancient attestation in the provided corpus classifies gallû/gallu as underworld demons; specific abilities or powers are not documented in the supplied ancient‑world sources. Modern role‑playing and fantasy adaptations (not primary evidence) depict gallu as manipulative abductors who worm into mortals' confidence and drag victims to the Underworld and grant them various game‑statistic strengths (references in the supplied notes to Planescape and Pathfinder material). These later attributions are creative uses of the name and are distinguished from the limited ancient attestation.
