Maybe this is too late, but I think we should incorporate the sacred Island of Delos as a province to our map. This place was considered a focal point of pilgrimage until the introduction of christianity. People from many religions and deities were visiting this holy place throughout the year. Imagine something like Jerusalem or Mekka of the Ancient and Hellenistic World. Temples of Apollo and Isis were amongst the more prominent. In particular the statue of Apollo was about 15 metres high and even today there are fragments surviving.
