Temporal Fusion
A TARDIS can be used to collapse an existing time couture by navigating through the corridor to close and seal the damage behind it.
This is done using the
Space Time Warping Template that collapse a TARDIS's breach in space-time during dematerialization.
If a malfunctioning TARDIS causes damage (such as a rift) to either the Multiverse or the Space-Time Vortex, it is sometimes possible to use Temporal Fusion to repair this damage by reversing the trip that caused the damage.
While Temporal Fusion can seal the "rift" it often leaves a paradox scar that can have minor effects on local causality.
It is likely that improperly performed Temporal Fusion could lead to Eigen Ram.
