The Dimensions are a series of interconnecting zones that lead to different parts in the universe, and a result of the Shattering, a tear in the space-time continum that consequently warped the entirety of reality to an irreversable state. As a result, many species, those native to Earth and other planets, have died in the millions. Most of the dimensions created are abandoned, having little to no signs of life on them, and those that do have people living in them are extremely few in numbers. There is no hope left for these worlds.
