The Celtic Legions

[Ranika]

Are you sure even about bribing them? As the Gauls, Greeks, and Germans, I've bribed the Illyrians in Illyria (which had all Illyrian mercs for the force in the city), and they joined my army.

And no, I've never seen any merc not available to everyone. As Parthia, I could could get barbarian infantry in Gaul and such.
