Donna Noble was coerced by the Trickster's Brigade into turning right instead of left on 25 June 2007; this small change in affairs produced Donna's World. In this world, Donna never met the Doctor, and so - without her intervention - the Tenth Doctor died in his confrontation with the [[|Empress of the Racnoss.
With the help of Rose Tyler, Donna forced her younger self to turn left instead of right, negating her world. The original Donna later displayed knowledge of the events of this timeline. (TV: Turn Left)
