Chrono Space

Chrono Space (クロノスペース Kurono Supēsu?) is the space used to facilitate faster-than-light travel and communications as well as being the main means of traveling in the universe. Traveling through Chrono Space is referred to as entering Chrono Drive and a ship in Chrono Space cannot be attacked by an enemy in normal space.

The Chrono Quake rendered transition into Chrono Space non-viable, causing the collapse of the EDEN Civilization and other advance civilizations across the universe.
