The Change represents the point at which “Magic” became viable on Gea. Prior to The Change, power was based on technology and science. These have largely fallen by the wayside as the seekers of knowledge have delved more deeply into Psionics, Arcania, The Primal Gea & Divinity as ources of power. There are, however, still some enclaves of the old ways, but they are few, as they have not withstood the onslaught of the “New Powers” and the denizians that would use them to usurp the powers of the nations attempting to hold onto order.
Scholars believe that The Change actually represents a point on a circle where the “New Powers” cycle from unworkable to viable. This obviously means that there would be a point in time where another Change occurs and they become unworkable again. None can say, however, how long the cycle is, and this leads many to believe that The Change is a permanent state.
