Creatures of the 4th Dimension, TARDIS units are exceptionally perceptive when it comes to the flow of history and causality and they can use this to aid their Time Lord operator in identifying and solving problems with the timestream.

When a Time Lord is inside the TARDIS, the bonus gained from their own ‘Feel the Turn of the Universe’ Trait is effectively doubled, adding a +4 to the roll instead of a +2. All TARDIS Units come with this Trait.
