Just a heads-up: I'm pretty sure this mod is incompatible with Compact Commissions and Translation and probably also Cultist Simulator Expanded.

Unless I missed something, you can't translate the books added by this mod without language cards, which the mods I mentioned above remove. Maybe there's a way around it, I don't know. Not any mod author's problem obviously, and I should have guessed it wouldn't work, but thought I'd post it here since I only realized this 10+ hours into my playthrough.
