Translated from the Back of the Book: The cult of Chrysir is rampant throughout the empire, and if it is on secrets that accompany relics and artefacts of this wind god, it's quite sure that the future will bring long journeys for the characters - maybe even travels on the wind itself. What these trips reveal, however, are secrets of so deep a past that even the wind does not whisper of it any more. What secrets lie hidden in Ciriadda? Do they hide the the key to immense power or do they bring death from the depths? Äonenstaub (Dust of the Aeons) confronts the heroes with ancient magic, the rites of the cult of Chrysir, customs of a tribe of the Leonir and aerial piracy - and is suitable for heroes of any profession and culture.
