Six down- four to go to!!: 4 faction slots left

[Arjos]

We can say Atropatene isn't going to be in. It would be impossible to fight against the seleucids and it would make the Hai even more difficult.

Yeah, although I'd like to see them (interesting Persian revival), afaik they held mountain passes and highlands, but settled to side with whichever ethnos allowed them local administrative autonomy...

I think we will see a Baltic faction as most of the land there is still unused.

I recall the team saying how the Baltic was added (at least partially) to the Eremos region; not to mention the Lugiones are right there...

For an Iberian faction, maybe the Cantabri

Not the most powerful around the 3rd century BC, but you never know :)

What about the Remi?

Must confess I do not know much about them in the 3rd century and also among the Belgae they are quite close (culturally speaking) to Gallia...
Not sure, but I think they actually migrated or eventually got surrounded by incoming Belgae...
