Before the first Olympiad, Caranus was moved by ambition to collect forces from the Argives and from the rest of the Peloponnese, in order to lead an army into the territory of the Macedonians.
At that time the king of the Orestae was at war with his neighbours, the Eordaei, and he called on Caranus to come to his aid, promising to give him half of his territory in return, if the Orestae were successful.
The king kept his promise, and Caranus took possession of the territory; he reigned there for 30 years, until he died in old age.
