Just a small consistency thing, but I think Literature Expertise sounds more like a Utility Expertise than a Cultural one. Cultural is for cultures or walks of life, where Utility represents trades or domains of knowledge.
Ardentia would be Cultural, Religion is Utility
Military Life is Cultural, Military Strategy Utility
I think in the case of Literature, the Cultural equivalent would be ‘Scholar’ or ‘Librarian’, while Literature should be Utility.
