A TARDIS has a stabilizing effect on the local area (~100 miles) of the Multiverse. The Environment Governor uses the Dimensional Stabilizers, Probability Compensators, and (on occasion) even the TARDIS's own exo-shell to fix or patch some kinds of space-time anomalies.
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. The object (or person) will remain there for up to half an hour before a TARDIS returns the object to its original 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.
Using the Governor the TARDIS can seal cracks in Time that lead to Parallel Universes, repair damage to the time lines, and act as temporal de-crystallizers The Governor can also deal with time eddies, time-ships, and temporal feedback. In an extreme emergency, the TARDIS's exoshell can even be used to plug some types of holes in space-time.
