Thanks for the feedback! And yes, definitely I'm a terrible, terrible layout artist. I agree about the SRD. I sort of fell into it. At first I was like, well, I have to change the equipment section. Then I was like, well, I also have to edit the cost of spell components. Then I was like, all right, might as well include as much as possible and just be able to present this to my players (especially new players) as a complete package.
And you're right -- the banking and corporate financing is modeled after the system used during the Renaissance, which is very at odds with the clearly antiquity-inspired setting. But I love the machinations of the Medici too much (the Keln Isles is also a place out of time, but hey, it's fantasy!).
Full disclosure (pretty sure most of this is cited in there, but since you mentioned it): Glad you like the economy and other bits! Credit where credit is due -- the Economy section is a mix of rules from Adventurer, Conqueror, King RPG, the Grain into Gold PDF, and our own rules, tweaks, and additions. The NPC Boons are actually swiped from Pathfinder (edit to add: and I agree, they're brilliant!). Naval combat is from a website that I cited in there (can't remember where), and if you go there, it's actually a lot more robust (we figured for our purposes, we didn't need all of it). And the Mass Combat section is a cross between a Pathfinder supplement I had written years ago and a tactical miniatures wargame called Field of Glory (the rules of which I love very much). Very much a Frankenstein monster (in other words, very much a homebrew setting!).
And again, you're right about the riddle. When I ran it, they had to eventually roll Wisdom checks or something in order to get it!
Thanks again!
