The Great Wall

Construction on this was started in 2587 L.  This massive wall spans the Northern Half of the Empire and took over 150 years to construct.  The massive walls soar up to the sky and are attached to 7 Sentry Castles.  The thick walls have been bolstered with magic and actually allow for massive troop movement through them.  Various magical enchantments allow for speedy movement allowing the Empire to redirect forces to different portions of the wall in rapid speed.  The 7 sentry castles are also supported in the air by Aarokocra and Gith Warships.  The walls themselves are further enhanced with a green rock like substance called Viridet that prohibits planar travel.
