Fiction:Window In Time

The Window in Time is a force of nature, a reality. There is only one, but it moves through space, time, and reality, allowing it to seem as though there are many or none. It doesn't exist in the same manner that most would think. It's more of a doorway, or a road.

Workings of the Window
The Window works by pulling two points in time together, allowing for something that passes through it to move from one point to another with ease. The window doesn't however, have anything... intentional about itself. it merely is, it has no purpose, no future, and no past. Only the present exists for the window, and all times are the present. What causes the Window to locate itself and what times it connects is unknown, and seemingly random. Those who pass through the Window cannot be "unmade" for it disrupts space time to the point of creating it's own space and time. It also "fixes" time on it's own. How is unknown, but when something moves into the past, there are no universes split off from each other, and no destabalizations of space or time. It's not understood how it does this.

Known "Windows"

 * The Window that brought the KIWI into this time and universe.
 * Theorized Window that brought the Grox, as an already advanced civilazation, back in time to the dawn of the universe from it's death.
