Kaiu Kabe

The Kaiu Wall, also known as the Carpenter Wall, for centuries has been a very physical demarcation of the southern border of Rokugan. On its north side lies the lands of the Crab Clan, and on its south the blighted stretches of the Shadowlands. It is here that the forces of Rokugan have entrenched themselves in their eternal battle against the forces of Jigoku.

Loaction
Originally, it was a wall built by Hida on the behest of Hantei. It ran along the southern Hiruma border until it was destroyed by the army of The Maw before the Battle of the Cresting Wave. Given time by Kuni Osaku, a new structure was built in 73 days, which runs along the Seigo River in 716. It has since been modified repeatedly over the years until it stretched from Razor of the Dawn Castle to the beginning of the Kuni Wastes.

Statistics
The Carpenter Wall is over 100 feet tall with its foundations sinking many 100 feet into the soil. It is almost 30 feet wide and is held by 150,000 samurai with enough rice to feed an entire army for two years. It has strong points located at 50 yard intervals, which house siege engines. Each strong point houses one crew for the engine and a further two regiments of troops of 50-100 bushi. Between the strong points even more archers and bushi are posted. There are also 12 main towers that line the wall from end to end.

Communications
Communications along the wall are Hiruma runners who will sprint a mile before handing their message over to an other runner. The system is surprisingly effective and the runners are known as the "Winged Falcons".

Passage Through
Under the wall the Kaiu have constructed a maze of traps and dead ends. All Hiruma Scouts who are about to enter the Shadowlands are provided with a Kaiu guide to lead them trough the mazes.

Tower of Fear
At the Battle for the Last Tower, Fu Leng corrupted one of the towers of the wall. Unable to cleanse the Taint from the tower, it was ordered to be broken from the wall and to rebuild around it. The resulting Tower of Fear stands within view of a considerable portion of the wall, a grim reminder of the consequences of failure.
