F.I.L.T.E.R., which started out as an initiative to stop the influx of terrible extra-terrestrial races, has become the organization in charge of jailing the most dangerous criminals and threats to our world. No government would acknowledge that F.I.L.T.E.R. exists, or that they can open portals to their time-locked prison The Block just about anywhere to book new prisoners. But they can. And they do.
The Warden runs a tight operation: besides the entire prison itself being kept separate from any known time-space dimension, the individual cells are cycled through time loops to nullify whatever powers or abilities the prisoners could bring to bear on the guards. However, there have been reports of disturbances within The Block, and someone should probably go check it out.

- The emblem of the F.I.L.T.E.R. agents is an image of a Gray, a popular type of alien. This is because, as noted in Tempest's backstory, F.I.L.T.E.R. was originally dedicated to monitoring and policing alien life on Earth before it expanded it's jurisdiction to super criminals.
- Kismet makes her final escape from the Block during the latter half of the OblivAeon events. The way that she leaves, "locking" the door behind her has an impact on the diverging timelines - she escapes into what becomes the RPG reality while the Block winds up as a "polyp dimension" attached to the Tactics reality. Neither she nor the Block exist in the other reality after the split (Letters Page Interlude 3).
- As an alternate dimensional prison, The Block is very similar to DC's Phantom Zone and Marvel's Negative Zone.
