For thousands of years the Protoss have studied the nature of time and space. Through their painstaking studies and experiments, Protoss researchers have uncovered many of the secrets of the universe. 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 Protoss use these "Warp Prisms" in several ways. The primary function of a Warp 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 Warp Prism.
