Nias'hal Wall

The Nias'hal Wall simply known as "The Wall" is a very long 20 meter high concrete wall which spands most of the Eastern region of Perk. The Wall was built by the Kingdom of Perk as a means to act as a major front line defense of all the vital sections of Perk. The wall spans a near perfect ring around the designated location except it being interrupted by the Kamsagal Mountains.
The Wall began its construction on the 05/02/3007 and was completed on the 26/06/3053. After each mile down The Wall there is an anti air and Anti ground railgun battery designed for the defense. The wall requires so much power that there is 4 fusion power stations hidden in underground bunkers specifically designed to power the wall.
Every 10 miles there is a major entry point in the wall to allow people to leave and exit, There is no major security ID needed to go in and out The Wall as The Walls only purpose is to defend against possible invaders.
Inside The Wall there is a highway which travels throughout the interiors designed to transport military vehicles in protection.
