I wasn't expecting an explanation myself. They were just plot devices although you would have expected the Sisters to have put something like the IM book in the dungeons or something.

I'm hoping that Season 5 might delve a bit more into the history of magic and of the Sisters' joint rule, evidently during the Classical Era.
