Loom of Rassilon's Mouse
From Tardis Wiki, the free Doctor Who reference
The Loom of Rassilon's Mouse was one of the artefacts of Rassilon. The Master stole it from Gallifrey and took it to Earth. He intended to use it to weave himself a newer, stronger body. His plan was stopped by the Seventh Doctor and some of the guests at Benny and Jason's wedding in Cheldon Bonniface. (PROSE: Happy Endings)
