A Sphere of Order is an area of the Sea of Chaos that is able to maintain its form amidst constant change. If it maintains this form for long enough it can provide a cocoon for other forms to manifest inside of it. Our story takes place in one of these spheres that has remained stable over a long period of time. These spheres account for an infinitesimal percentage of the space and energy of the Sea of Chaos, but since the sea is infinite, there are an infinite number of these spheres. However, the distances between them are so vast as to defy measurement.
The sphere in which our story takes place is expanding and contains many galaxies of stars, planets, and other phenomena. The Pilgrims watch over all and ensure that Chaos does not seep in and gain a foothold within their sphere.
