Apportation was the word for objects appearing during séances. It predated the coining of teleportation by Charles Fort in 1931.
During The War, however, it was a tactic used to duplicate objects or people so as to cause confusion. One case was that of Elisabeth Canning, who disappeared in England in 1753. Reliable witnesses swore that the chief suspect, Mary Squires, was in London near the home of Mother Wells and Dorset at the time of the disappearance. Though sentenced to death for the crime, the conflicting testimony led to her release and exile to New England. The duplication was achieved by Robert Scarrat through a process of Time-Thickening and believed to be a possible indirect attack against Faction Paradox. (PROSE: Apportation)
