Just a bit of knowledge :)

Say, we played Broken Covenant of Calabeis recently, and the Magi found some tractatus on Roman History. But then I noticed that there doesn't seem to be any skills on this in the rulebook. Which skill would cover skills in history and such?

E.

I'd say Lore boss... Roman Lore or some such. What it'd be useful for though... I have no idea.

I'd say it's a type of Area Lore: (Roman Empire) Lore, perhaps.

Organisation Lore: Roman Empire (History) perhaps

I would say Area Lore: Rome; history is a specialty within Area Lore.
