3 Black actors constitute a majority now?

You mean to tell me that the possibility of there being black people in the Persian Empire were slim to none?

If we use wikipedia as even a slightly decent source, the Persian Empire during the Greco-Persian wars consisted of, but not limited to:

the east modern Afghanistan and beyond into central Asia
portions of Baluchistan;
in the north and west all of Asia Minor (modern Turkey)
the upper Balkans peninsula (Thrace),
and most of the Black Sea coastal regions
in the west and southwest the territories of modern Iraq, northern Saudi-Arabia, Jordan, Israel, Lebanon, Syria, all significant population centers of ancient Egypt and as far west as portions of Libya.
