The Environment Governor of a TARDIS has a stabilizing effect on the local area (~100 miles) of the Multiverse. If any object's Time-State changes or its Reality Quotient gets too low, then a TARDIS will "catch" the object and put it in the Catch-All Area. This is a cream coloured room in a TARDIS interior, which has a fountain. The object (or person) will remain there for up to half an hour before a TARDIS returns the object to its original Spatial and Temporal Coordinates. To protect a TARDIS from infiltration, the Catch-All Area is completely cut off from the rest of a TARDIS and barricaded by the Force Field Prisms.
