Memory weave
The Memory Weave was a device capable of extracting memories and turning them into physical objects. The Claw Shansheeth of the 15th Funeral Fleet tried to use a Memory Weave to create a TARDIS key through the memories of Sarah Jane Smith and Josephine Jones. The machine was overloaded when the women remembered all of their time with the Doctor, and other significant adventures from their lives. The machine exploded, apparently killing Tia Karim and the Shansheeth. Sarah Jane and Jo survived by taking shelter in a lead lined coffin. (SJA: Death of the Doctor)
Behind the Scenes
The sound effect used during the activation of the Memory Weave was the same sound effect used in the Ghostbusters movies, cartoons, and video games for powering up a Proton Pack. [source needed]
