Dimensional warp drive
From Jenny Everywhere Wiki
A dimensional warp drive was a component of Cupid Fog Ships, or at any rate of Pessimist's Fog Ship.
When seeking to prevent it from leaving her Workshop, Madame Tarsa removed the dimensional warp drive from the Fog Ship. In this state, it could still fly around and generally operate normally, but not warp out of the dimension of the Workshop. (PROSE: The Toymaker's Labyrinth)
