Yep, we could just call it mercenary port or something, seeing the cities we have chosen it could maybe also add extra trade income.
So how are we doing that with the mercenary center? Since we would still have Greek hoplites or Aitolian peltasts available as mercenaries in Aitolia the normal way, should we use that for the ''international'' mercenaries everyone used? Thracian infantry, Thracian cavalry Galatian infantry, Galatian cavalry & Cretan archers, most of all.
