Time spillage

Time Spillage was when time accelarated out of control causing non-time sensitives to age rapidly, which usually happened in the presence of a TARDIS which has either been tampered with or was faulty. An example of Time Spillage happened when The Rani visited Killingworth in order to gain the chemicals she needed to calm her experiments on Miasimia Goria, where The Doctor had gained access to her TARDIS, and tampered with the controls and set it to allow time to accelerate whe The Rani dematerialised. This flung the Rani and The Master towards the walls of the TARDIS stopping her from undoing the effects. Her samples of dynosaur embyro started to grow durring this effect. (DW:The Mark of The Rani)
