To sound like a serious educational piece, the writer fancies themselves as an historian.
Or maybe there has been a time slip and the piece is from the thirty fifth and a half century.
The writing in the game is pretty poor. And don't forget - it's in the top 1% of poor writing out there.
I really wish FD would hire a professional writer with a solid - not even deep, although that would be preferable - grasp of the setting and the ability to write dialogue.
