Phantom Zone

The Phantom Zone is a region of space in which time stands still, and from which extremely little escapes.

History
The maximum security Kryptonian prison, Fort Rozz, was banished to the Phantom Zone at an unspecified date.

Some while later, Kara Zor-El was sent to Earth. However, her ship veered off course and she was stuck in the Phantom Zone, only arriving on Earth decades later. As Kara left the Phantom Zone, she pulled Fort Ras with her.
