DigiQuartz

The DigiQuartz is a mysterious space between the Human World and Digital World which is used as the field for the Digimon Hunt. It manifests as a digital mirror of the Human World. It is quite fragile, and the matter within can disintegrate into data at a touch. Due to the DigiQuartz's connection to the Human World, the events within it often play out in the Human World through various analogues, such as windows blowing out or objects moving around. Over time, the DigiQuartz has expanded outside Japan, and manifested in locations as far away as Hong Kong or the USA.

Various Digimon manage to find their way into DigiQuartz and are lost there before being drawn to and corrupted by the power of human emotions. While Taiki attempts to get to the bottom of it at his end, Shoutmon has been attempting stop his fellow Digimon from traversing into DigiQuartz. Hunters must use a "Time Shift" with their X Loaders to enter the DigiQuartz, but many of the corrupted Digimon can simply draw in human victims from the other side.

The DigiQuartz imposes several rules on Hunters, most of which limit their power. For example, it is impossible within the DigiQuartz for a Hunter to realize more than one of his Digimon at a time, and they can only DigiXros two Digimon together at a time.
