Fifth-Dimensional Perambulator
The Fifth-Dimensional Perambulator is a Sterility construct devised and built by Nuck Chorris, which, while not fifth-dimensional itself, facilitates translation across the Imaginary Plane.
As a sterility construct, the Perambulator requires a considerable amount of Sterility to use and is designed to be operated only by a seasoned C.H.E.S. master. According to Nuck, the shape of a perambulator is considered ‘aerodynamic’ for intraplanar translation, reducing quantum ‘drag’ and allowing for farther translation while using less sterility.
Nuck doesn’t actually make use of the Perambulator, as he doesn’t need it, but it is frequently used by his butler, Santiago Petterson, do dump dangerous byproducts of the tea-making process at the Safe Asymptote.
