How many legions are left and what is the status of them?

[Kesey]

However, I also get the impression Garlemald isn't that analogous to Rome, in that I don't think we've heard about the equivalent of how Rome kept sending generals out to conquer territory, and then the generals went back home to try to conquer Rome itself, and this kept happening over and over again. I don't think that happened to the Republic of Garlemald, since it would presumably be a major enough event to warrant mention.

Or it happens so often it isn't worth reporting, or is just a small footnote in the historical record. Also, haven't the Garleans fought two civil wars off screen in the current timeline of the game?
