The TARDIS has an almost childlike curiosity about other places and times and, if left too long, it will occasionally nip off for short jaunts when its operator is away in order to slake its thirst for knowledge. These trips can last any amount of subjective time, with the TARDIS having many ‘adventures’ of its own, like being worshipped by a strange primitive tribe it is observing or becoming caught in a prehistoric mudslide that leaves a fossil impression destined to blow the minds of future palaeontologists. It will attempt to return to its original point of departure within a few seconds of the time it left, but on occasion a Time Lord will return to find their TARDIS a few yards away from where they landed it, covered in primeval mud that wasn’t there when they left it, or missing altogether when they need it.

Once per adventure, when the GM determines that it has been left on its own for a good bit of time, the TARDIS must make a Resolve roll at a Difficulty of 12 or sneak off on a trip of its own. The results of that trip should be randomly determined (see the Random Trip Table above).

Each trip costs the TARDIS 2 Story Points, one for leaving and one for the return trip, as normal for its use of the Vortex Trait.

This Trait raises the TARDIS’ Story Point total by 1 and the TARDIS Knowledge skill by 1.
