Argossean Foundation

Description
Foundations should be the starting point for almost any structure. They provide stability to anything built atop them and prevent the growth of plants beneath them. Placing a foundation is a significant act in the Exiled Lands. Once a foundation is placed by a clan or individual, that land is considered their territory. Nobody else may build in the immediate area, unless the foundation is destroyed. Weapons barely chip it and even explosive powder is not enough to weaken it in a single blow. Siege weapons or divine intervention are really the only way to bring down walls this strong.
