The Lord of Air, Skies and all Beyond.
Ahriman first appears in ancient lore of men, deep in the southern deserts. He is said to have been the wind that rises the dust devils and sandstorms to plague men and other folk. Reports of Ahriman being a slightly fat, oilyskinned man appearing in bazaars have been heard. Naturally the lord of air (if he indeed exists) would be a powerful elemental being rather than a god.
The one thing everyone seems to agree on is that he is definitely full of hot air, be he in humanoid form or in his natural elemental form.
“Buying promises is like striking a deal with Ahriman” is a known proverb in the Golden City.
