Great Walls of Morales

The Great Walls of Morales, also known as the Sebastian Walls, is the series of defensive stone walls, now made of steel, concrete, and other hard resources and esoteric (thaumaturgical) materials, that surrounded and protected Morales (Morales Metropolitan Axis in Armanya, Morales Megalopolis in Novaya IV). Based on the Walls of Constantinople, especially the Theodosian Walls, and the Chinese city walls, the Great Walls of Morales were designed to protect Morales as well as resist enemy sieges. Through studies on the Walls of Constantinople and Chinese city walls and by applying the Chinese Wall Theory, the Great Walls of Morales were designed to be vertical at the front to better deflect projectile energy.
As part of the construction and designs of the Great Walls of Morales, the sea walls were made to follow its design, with studded bastions and soaring fortresses built at several locations, and gatehouse forts built. A moat bigger and deeper than the one in front of the Theodosian Walls is dug. Hidden gates were also set up to allow troops to launch sneak attacks, and staged killing fields set up between the walls and before the moat to allow for heavy casualties against enemy forces. A deep defense architecture is also implemented to heighten the walls' structure and defensive capabilities. Cities, towns, villages and municipalities located outside of Morales were made as strategic exclaves, whose walls were built up to heighten their defensive capabilities. Esoteric and thaumaturgic materials were used to amplify the walls' defensive capabilities and equip it with shields and thaumaturgic reinforcement symbols etched on the front and back sides of the walls. Finally, a military officer or civilian with years of military experience is appointed as the Walker of the Walls, and a watchtower network and retinue set up to maintain and protect the walls, both within and without.
The Great Walls of Morales is used as a catch-all term for defensive walls where some most populous cities were equipped with such to resist sieges.
