As said in the Valyrio topic I really got some inspiration from Assassins Creed II. So used the idea of a Borgia Tower and turned it into a "Garra Tower", with the tunnels/sewer system and secret chambers. Ofcourse I also had to put in Besdarc Menteno posing as an assassin. Just posing ofcourse. . Enjoy!
Garra Tower
In Valyrio the Garra, the elite units in the Corisar, have special towers under their command. These towers watch over the lands and when needed the Garra can act swiftly where needed.
Secret treasure chamber.
Garra conference room in the basement.
