wellllll, Maion always talks as if he knows what he's saying, and I'm not historically inclined enough to correct him if he's wrong, but if he goes a step wrong when describing north-welsh castles from the 13th century Then I will be on him faster than a rainbow on an oil slick... Anyhoo now that I think about it there are a few factions that I'm not sure of their pronunciations:

Arche Seleukia (Arch or Arch-ay?)
Aedui (Aydwee?)
Epeiros (epeeros?)
Qarthadastim (car-tha-dast-im or cart-ha-dast-im?)
