Before I get to the meat of my post, let me congratulate you, Kael. This is a towering achievement of a mod - I think you've created the Counterstrike of Civilization. Amazing stuff. Anyhoo, I fired up a test game, and here's what I've noticed.
Dragon's Horde should be changed to Dragon's Hoard.
Why does the starting settler have such incredible visibility and movement?
My domestic advisor shows no information - perhaps this is because I have a preexisting mod for that advisor?
The tech quotes could use some work, I think. Down the line, the concepts behind the quotes are great - it's the diction that could use some work. Here's how I would go about tightening up some of the phrasing.
Writing - "I am greater than any magician, my pen more powerful than any wand. For inside it lies the laughter of every child, the tears of every man, the hearts of every woman, and the hopes and fears of every being." - Elven Bard
Polytheism - "The monotheistic God is distant, inscrutable, ineffable. Our great pantheons, however, show us ourselves in the images of gods. Our tragedies, our dramas, our joys, played out in the greatest of scales by the greatest of beings."
Philosophy - "My study of philosophy has often been deemed frivolous. 'Philosophy!' they'll snort. 'Each answer yields only more questions!' And yet a single answer and a dozen questions is better than none of either.
Sailing - "The ocean - she's a dangerous wench. She'll give you everything you need... your freedom, your food, your livelihood. But catch her on a bad day, and she'll snatch it all back" - Some sailor
Hunting - "Man is the most impressive of predators, for Nature saw fit to give him no advantages. He had to fashion his own fangs, carve his own claws. And now even the greatest of the beasts fear him."
Militia - "I'll not lie - my hands are more accustomed to the hoe, rather than the sword. But when I am called, I pick it up, all the same." - Gerold Marne, farmer [Ed's Note - Jiz seemed like a very unfortunate surname]
There's a slight typo in Warfare's tech quote.
Octopus Overlords sounds a bit cheesy to my ears. Maybe you could name the religion "Disciples of the Kraken", or "Disciples of the Deep", or something.
For the smokehouse (what a wicked concept!) it mentions you get +1 Health from Cow, Pigs, Sheep. And then in the tool-tip it mentions you also get health for Deer.
I created an Adept in a city with a Training Yard. I promoted him with the Haste upgrade, and ended the turn. The next turn, the very same adept was asking for a promotion. I hovered over it, and it had no mention of the Haste upgrade I gave it last turn - it's as if I had never upgraded it to begin with. This happens each turn - the promotion just won't stick.... OH! That's a spell effect, isn't it. Well, I feel more than a little embarassed.

Good feature.
Should reagents provide food? Maybe if they provided commerce and a science bonus when you put a plantation on them.
Why can The Drowned move over mountains?
Anyway, I'm all Civved out for the night, I'll add more thoughts when I get back into the game.
