Imagine a planet called Hasheraq.
Imagine the EMPIRE gained control long ago, wiping out the worlds heritage and creating a puppet government operating under the watchful eye of small Imperial garrison. Only in tribal caves in the deep deserts of the world survive the old ways, culture, history, tradition... and prophecy.
Enter the young MESSIAH, the chosen one, either an orphaned farm boy or a noble born outcast appearing in the desert. He is accompanied by the OLD MAN OF THE DESERT, a hermit of incredible power once a mystical bodyguard of the HOUSE IMPERIAL, turned native sympathiser in years long past.
Enter the DESERT TRIBES, lead by tribal leaders:
Enter the PEACEKEEPRS, local born recruits trained by the EMPIRE to police the people. The appearance of the MESSIAH challenges their allegiance and many now side with the UPRISING.
The IMPERIAL COLONY OF HASHERAQ is in turmoil, time to send in the elite fighting force to quell the rebellion and destroy the INSURGENTS, the white and grey IMPERIAL MARINES.
The UPRISING will need to find it's DESERT POWER.
