The Ancients were the first known crystal technology users. Control crystals were used in varying arrangements to activate, modify, and direct the function of their powerful computers and other instrumentality. In the Pegasus galaxy, these took the form of flat, clear, geometric units. This is a set of crystals of the type typically found aboard puddle jumpers but also seen in use with other Ancient technology.
