The Book of DieselThe Light Before the Gospel“Outside the terrace, Leontes looked back at the flames and said he had joined a campaign against an empire, not against the dead. Atar wanted to strike him. Instead he gave him one charred page listing Greek prisoners once treated in a Persian clinic.”

Historically anchoredThe setting or public event is documented; dialogue, motives, and recurring characters are invented.
Alexander occupied and burned Persepolis; motives and circumstances are debated, and later Zoroastrian tradition remembered him as a destroyer of religion.
The rescue of the Keeper archive and the exact library fire are fictional; claims of Avesta destruction belong to later tradition and are labeled as such.
