Mechanically, I really love this faction. The gameplay feels simple, highly interactive, and genuinely interesting to play. And the artwork is gorgeous (no burning books reflected in the owl's eyes, though? 🙃)
My only slight critique would be regarding the tokens. While "Bookshops" absolutely works mechanically, the concept feels a little flat compared to the rest of the theme. I feel like the faction would gain even more narrative depth with a slightly punchier or more evocative name for them. But that might just be my personal taste!
