 The Prophets , or San 'Shyuum , ( from the planet Janjur Qom ) serve as the royal rulers of the Covenant , and were primarily designed by Shi Kai Wang and Eric Arroyo . Originally , the Prophets were built in a more unified way , with the gravity thrones they used for flotation and movement fused with the Prophet 's organic structures . The characters were also designed to be feeble , yet sinister . The three Prophet Hierarchs were each individually designed .
