The Byonder's Rift-
Backstory: The name for the aftermath of a failed technique used by the ancient Azendi from the Byonders faction to try and obtain a non-physical form. Little is know about the technique used, but rumors say that at the cost of a Azedi's life and a large amount of cosmic power. A large cloud is formed that masks all things inside of it after the course of a minute as long as the object inside remains perfectly still.
Maybe not the most scientific name, but it was fun to write.
