THE FORCE OF THE FAITHFUL
Belief in Great One, above all else
The people of the Null live their entire lives, from their birth to their death, in service to the Great One. From the moment of their birth, until the moment they die, no member of the Null is ever alone. The voice of their god speaks to them, guides them, every step of their lives to live in His honour.
But amongst them, they must always be watchful for any signs of heresy. Ever since the great schism, when the traitors had requested use of their own free will, the great god's faith back to his people has been shattered. Every day, the voice of their god searches through his people, search for any signs of the heresy, ready to destroy any signs of it. When the rift opened, the minds of all those not loyal to the Great One appeared, mind's He couldn't even speak to. This was not tolerable. The Null would go to war.
MUSINGS OF THE HIGH PRIEST
The High Priest is the oldest of The Great One's followers. He should have died centuries ago, but his god keeps him alive. And he will serve, for as long as his God needs.
