The Defiance Defense Perimeter (DDP) is a 3,000+ mile long system that serves as the primary defense of the Hurian Federation, and the bulk of its population. In the event of a foreign invasion, the area within the DDP would serve as a sanctuary for the Hurian citizens, while the perimeter itself was fortified with Pride Defense Towers, and a number of other military installations and weapon arrays. The system was completed in 1998, and has been undergoing constant upgrading and maintainance since then. The DDP was been named of the "eight wonder of the world" by prideful Mandinka engineers.
