Rome’s expansion to the east has not advanced without difficulties. The previous expedition was never heard of again, after their arrival to the Lycian coast. I have received some reports of hostile Pergamum armies are active in the region and seems so that they have not accepted our presence near the Mediterranean coast. Build a fort settlement to defend the region. Once we have defeated their armies, we can conquer this province under the Roman banner.
Imperial pioneers have found a suitable coastal site with abundant fishing grounds, which seem suitable for our endeavour. In addition, the passage by land is difficult to reach for this region, so you must rely on maritime traffic. This task will not be easy, beware of the Pergamum bows!
TL;DR:
Standard C3 style mission
Many invasions, fill requests to gain favor
Notes: One-time testing had a bug that invasion didn’t spawn enemies, other times worked properly.
