Hello, as someone from Romania I would like to suggest the following borders for Dacia in Rome Remastered:

The red territory represents the territory conquered by the Romans in 106 AD. The orange territory would later be conquered by the Iazyges.
Sarmizegetuza (Red) -> Capital of Dacia during the reign of Decebalus
https://en.wikipedia.org/wiki/Sarmizegetusa_RegiaDocidava (Orange) -> Dacian fortified town.
https://en.wikipedia.org/wiki/DacidavaArgedava (Pink) -> Capital of Dacia during the regin of Burebista
https://en.wikipedia.org/wiki/ArgedavaZargidava -> Dacian town mentioned by Ptolomei
https://en.wikipedia.org/wiki/ZargidavaThe Dacian tribes owning them in the Grand Campaign:
Tyregetae - Zargidava
Carpi - Argedava
Dacians (Tevriscii but essentially main faction) - Sarmizegetuza, Docidava
This is a map of the territory of the Kingdom of Dacia:
- During the reign of Burebista 82 - 44 (larger)
- During the reign of Decebalus' 87 - 106 (smaller)
