Haagenti

In the canonical Goetic tradition (the Lesser Key of Solomon/Ars Goetia) Haagenti is listed among the Seventy-Two spirits catalogued in that corpus and given the formal office of a 'Great President of Hell,' ruling thirty-three legions of demons. Alternate names such as 'Haage' and 'Hgog' are attested in the same corpus and later summaries. Later fictional and gaming material (Greyhawk, Pathfinder, other roleplaying and trope compilations) reinterpret Haagenti's origins—portraying him variously as a demon prince of vice, an ancient forged construct, or other cosmological types—but these are adaptations layered atop the Goetic listing rather than alternative traditional origin accounts.

The Ars Goetia description depicts Haagenti as a large bull with the wings of a griffin who, at the conjurer's request, changes into a man. Modern and gaming sources vary in visual detail: some present him as an eagle-winged minotaur or as a snake-man/yuan‑ti variant in certain retellings; these alternative forms appear in later adaptations rather than in the primary Goetic description.

According to the Ars Goetia summary, Haagenti 'makes men wise by instructing them in every subject,' transmutes all metals into gold, and changes wine into water and water into wine. These teaching and transmutation functions are the core powers recorded in the grimoire tradition. Later fantasy and game sources emphasize related themes—alchemy, the pursuit of knowledge, and sometimes associations with gluttony or other vices—but those thematic expansions are modern reinterpretations of the Goetic entry.
