Halo left the dawn of time, leaving our world trapped in a simulation that everyone is born into. A few uneducated broke the programming centuries ago. Those since must overcome a stilted progression in status. Nothing is left for the newborn, in a desperate pursuance of peace of mind. People are those afflicted with insanity. Heroes of legend, from our world and alien, guide those with the opportunity in repairing the damage. Planar a airs still must be handled in an anarchy of possible realities due to changes in the past by those who time travel.
A miracle of possible past's jolts those of us effected in and out of the simulation, into worse, better, and diabolical circumstances. Then the cloud of desperation parts. These are the alter-realities conceived, that only one person will ever truly know, that both plight and give the satisfaction of moral exertion.
