Uh, guys? Beaversdam just became a little town. The isle of Galma on the other hand, closest of the Lone and Seven Isles to Narnia, and most civilised, actually had a high reputation for producing seaworthy sailors/soldiers et al. There's a place worthy of seagoing bonuses.
That's my ha'penny - everything else I wanted said has been said. Except...
@ King Numero - The Tombs of Tashbaan and the Great Temple of Tash are both by the same settlement. Can the engine actually do that? (I won't argue it's unbalanced, because it is the capital after all)

Given the timezone chosen for the mod by Oscarreeve, I don't think that Cair Paravel should be a wonder. At the time, it was only a castle (an impressive one, granted, but still...) If we were playing @ time of Prince Caspian or there abouts, then yes, because it had passed into folklore. But otherwise, it's like making the Tower of London a wonder in Chivalry:Total War
