Should I add that Iberian horses are almost as legendary as Illyrium horses. Historically this is true.
I want to play as Scythia (around modern day Kiev). Octamasadas is my King. My people are mostly serfs farming margin crops like wheat. The army is largely horseback as par with the massive steppe around me.
Catalonian people are legendary Riders, Archers, and Sailors. Historically the area was colonized by Greeks, however Barcelona is a Collection of tribes who united under a King. Named Romulus
Just a side note, the Welsh were able to take all of wales by joining tribes together in their native tounge
I feel sorry for whoever got stuck researching "Greek Colonies of the Northern Black Sea in the year 450 BC" for their entire life.
