The Heaven's Gate is a chaotic area of space that appeared in South America and disappeared five years before the beginning of the series, along with everything in a 1500 km radius around it. Its exact nature at this point is unknown in the series. Its appearance apparently started a large-scale war, one that Great Britain and Argentina participated in. It also seems that Amber, Havoc, Hei, and his sister Bai, were involved in the War and were adversely affected by the Heaven's Gate's sudden disappearance. The area where the gate was has become inaccessible. Interestingly enough, Heaven's Gate and Hell's Gate are located on opposite ends of the globe. However, it is revealed later in the first season that, despite the Gate's apparent disappearance, Dr. Schroeder, a scientist studying the Gates, believes that, due to no person being able to enter the area where the gate formerly was, combined with Lancelnopt synchrotron radiation still being detected there, the Gate still exists in some form that is invisible and intangible.
