Paradox Engine

The Paradox Engine was a machine created and used by the Master, using Gallifreyan technology, to wreck havoc across time and space by having it create the Paradox Cloud to terrorize and change things into something else.
It was destroyed by the Thirteenth Doctor and Yasmin Khan when they arrived on Regnidorch II to solve the mystery of the Cloud. (GAME: Hidden Mysteries)
