For thousands of years the protoss have studied the nature of time and space. Using psionic manufacturing processes, the protoss have learned how to create a robotic mind whose programming is built into the molecules of an advanced crystal lattice. This "crystal computer" is able to manipulate matter and energy with a precision no ordinary organic mind could comprehend. The primary function of a phase prism is to transport protoss forces on the battlefield. Living and inorganic subjects are transformed into energy, and their unique signature imprinted into the prism's crystal lattice core. On reaching the desired destination the operation is reversed and the stored energy signatures are reconfigured into matter in proximity to the phase prism. When connected to warp gate [...], it´s possible to send units directly into the front lines. A secondary but no less vital function of the phase prism is to act as a mobile focus for the protoss psionic matrix. Once the prism is deployed it can power protoss structures around it. In this configuration phase prisms can be used to temporarily replace destroyed pylons [...] in a colony or enable the rapid establishment of a forward base of operations. [1]
