Timeship

From TARDIS Index File, the free Doctor Who reference.

Timeships were vessels constructed by active Temporal Powers to travel through time. They could be both ships in the traditional Earth navy sense of the word, hard physical objects that thrust their way through time (and often) space. (FP: The Book of the War) While other timeships were more modelled space-time events, either existing through their movement through time, or building themselves, modelling onto the universe slowly building a real world interface, I.M. Foreman's Travelling Show functioned in this manner. (EDA: Interference - Book Two)
