The Chasm

The Chasm is an alternate realm existing within the plane of a different universal dimension that is consumed by darkness and foreboding evil, and mirrors the home of it's visitors. It has channeled itself over many, many different iterations over the course of time's existence and as each universe rises and fades. It hadn't been discovered in this time until The Juggernaut seemingly opened a portal to, and gained power from the Chasm in 2072.

Before the end of Nuit Infinie in 2095, the details on the Chasm were extremely murky and only known of by a handful of people. It's connection to Cybertheism is mysterious but obvious, as most people who were familiar with it's existence were involved with Project V, as follows; Victor Moore, Marcus Caine, Lionel MacTavish, Astrid Newman, Melina Carballo, and Vaughn Porter. The only ones that weren't involved were the Yukinaga brothers, however they had studied the very essence of Cybertheism so patiently that they eventually found out about the Chasm and its still unanswered secrets.

The Coldest Winter
Victor sometimes discussed an event known as "the coldest winter" in relation to the Chasm's dominance in the saga. It most likely refers to a hypothetical "victory" of the Chasm over the Earth, fully reclaimed. What would happen to humanity during these times are unknown.
