Time storm
From Tardis Wiki, the free Doctor Who reference
A Time storm is a method of time/space transportation that can be viewed and experienced in many forms. Typically it is directly experienced by the people being taken through time as a swirl of coloured light, and unlike traversing the vortex in a TARDIS it is a tangible experience. (DW: Silver Nemesis)
Fenric took Ace through time in a time storm from her home town in Perivale, Earth to Iceworld, Svartos in order that she would meet the Doctor and then come to be of use in the final game against the Doctor. (DW: Dragonfire, The Curse of Fenric)
Fenric also took Lady Peinforte and her manservant Richard Maynarde from 1638 to 1988 in order to manipulate them into gathering the Nemesis statue. (DW: Silver Nemesis)
