Instead of reading the source code or seeing it, the Prophet can feel and experience the network as if it was a living entity. They can use the whispers of the network to their advantage by knowing which one of all possible future happenings will come true. If they are in the company of one of the Immortals, the Prophets can act as a bridge and make some of the immortal's power, albeit less powerful, available to the more common glitches.
