Arcane Academy- reagent generation should be left for a guild to. In general I'm not particularly impressed, and it doesn't seem all that original. (I would probably like this better if I didn't have a habit of cheating to get xp when I need it
)
City of a Thousand Slums - This shouldn't have alignment restrictions, and it's too good to not have some downsides. It should cause significant unhappiness and unhealthiness so that it won't be overpowered. Giving the Kuriotates a
fourth ring could be pretty cool, but if so it should probably have an even larger health/happiness cost.
Conclave of Blades - Enchanted Blade is already too easy to get. I'm not sure allowing your arcane units to use metal weapons promotions is possible. (It could probably add the promotions, but they would be removed when they are upgraded)
Great Brewery - probably too strong for the dwarves, not so much for others. I'm not really a fan, possibly in part because I don't drink. The name needs work. The only deity that would make sense in the quote in Kilmorph (she is the dwarves' goddess, as well as the goddess of the harvest season), but I think they see gems and mithril as better signs. I'm not really a fan of ripping of real life quotes like that, especially ones that are so well known.
Mirror Mirror- Are you sure this doesn't violate the Princess rule? I don't really see a place for it in FfH even if you don't think the princess rule is relevant here.
Pan's Meadow- I would rather have this grant extra healthiness, happiness, and a bard per forest (since thats possible now). Not bad, but not my favorite.
Port Royale - This one is my favorite. Everyone should vote for this one. Immunity to blockades and defense from enemy ships is great. (I'm not sue sure about the free visibility of other ports, even if it is possible.) This also makes me think that each leader should get a "Least Favorite Wonder," which would leaders would hate you for building (although it wouldn't necessarily stop them from building it). This should be both Lanun leaders' least favorite, the Infernal Grimorie's Basium's least favorite, etc.
Sacrifice to Bhall- Peace with barbs should be handled though a repeatable ritual instead of a wonder. In general, this would be better as a repeatable ritual or a spell (perhaps available through the Eternal Flame equipment that the Clan will eventually get as a trophy). I don't like it at all as a one time thing. Planar Gate creatures don't have much to do with Bhall, and they would take away from the Sheaim uniqueness. (of course, if there were a repeatable ritual with this effect, I would rather it be more like my entry into the event contest)
