I like this faction! My major feedback would be to clarify when cards in the archive are face up or face down. If it’s always face up I would love to see that, perhaps in the archive box on the player board as reminder text. As it currently reads, you reveal the archive progressively and presumably you keep those face up but as you add cards do you ad them face down until you reveal them and then that’s the point at which people can swap from them? The faction centering around that zone and the rules being foggy around it was a bit of a downside for me but overall cool concept.
It also seems like the faction would draw a lot of cards. Only needing to build one bookshop in each suit to get your first extra card seems kind of insane since you can build your first one before your first draw step, and I imagine that starts to get out of hand quickly. I also wonder if the bookshops should need to be adjacent to the library or other bookshops when being built instead of just being airdropped into anywhere on the map (as is my interpretation of the current wording). These are both questions for playtest but they’re worries I have about the overall balance of the faction. Maybe this is all offset by how hard it is to get warriors on the board, I’m interested in your feedback.
