your stronghold seems to have more buildings than Raedric's behind the wall, yet Raedric is still definitely richer than you. he can rise an army, while your watcher can only have 8 guards. maybe the security level means how many armed men you have o how well their equipment are, but they just refuse to join you when you decided to end raedric's rule
maybe that chair is the real lord of caed nua, the old watcher already seen though it, so he locked himself up underground to avoid been manipulate by that chair, but the young watcher is still too naive to recognize the truth behind those words, so the tax is going directly to the pocket of the lord chair, and you, as a poppet, gain almost nothing.
don't forget that the one who lives INSIDE of the main keep is the lord Chair, and you can only sleep in a 3 star hotel OUTSIDE of the main keep, don't mention that even those 8 guards can sleep inside of the main keep. your watcher is nothing but a dog who has a fancy dog house along with the kitchen, yet still not allowed to share the same roof with your domina.
still complaining the idea of having a stronghold? too young too naive!
