When Arse-a-mess and Sissy-gambits decided to have a baby, they never would have guessed that their son would come to rule over an empire that stretched from the Nile to the Indus river.

Artashata took on the name "Codomannus" pretty soon after he was born, stating it had "a much better ring to it." When he became the king of Persia, Codomannus decided to adopt "Darius III" as his throne name for some reason.
