In 324 BCE Alexander the Great is alive, undefeated, and supreme — and he has done one thing history never recorded: he has granted Egypt to Aeson of Thinis, a general of Greek stock raised on the Nile, displacing the man history gave it to. The grant is real. Everything underneath it is not. Egypt is a functioning kingdom — temples, scribes, garrisons, harbors, a thousand years of habit — and none of it has yet answered to Aeson. What he holds in fact is ten thousand veterans of the eastern marches and a brotherhood of officers who would follow him into the sea.

A year from now, the king dies in Babylon, and the greatest empire the world has seen falls into the hands of the men who conquered it. History records how that contest ends: Ptolemy's Egypt, Seleucus's Asia, the long wars of the Successors. But here recorded history is a baseline, not a script. Egypt's name will not go on the auction block a second time — and what happens from Babylon to Ipsus depends on what Aeson makes of the richest river valley on earth before the king's death arrives.

Prove the grant. Win the temples, the treasuries, the garrisons. Measure the grain, count the drachmai, keep the ledgers honest. And when the marshals gather in Babylon to divide the world, be at that table — or be divided by it.
