Teskoy Prison is accessed via a similar method used in the portal generators in [[Portal hub facility]] installations, however the portal generator is considerably smaller, and is mounted upright, generating a portal that can be walked through. This portal has a destination within an empty room, as such entry and exit from the pocket reality is only possible via a portal generated from outside the reality itself.
Due to the start of the failure of the [[Inner Shield]], Teskoy Prison has in some way become linked to or merged with [[The First World]], which has resulted in the release of its many dangerous inhabitants onto the relatively unprotected population of [[The First World]]
