I remember this lovely method of transportation from the Ravenloft supplement Von Richten's Guide to Fiends.
Basically it explained how fiends made their way into Ravenloft by slowly switching physical places with a mortal. Said mortal would show varying changes in behavior and appearance as more of the fiend's nature bled through, essentially using his body and soul as a sort of portal. There was even a small chart showing the level of corruption and the corresponding stat/ability and personality changes, including charming bits like "a character in the second stage of transposition with an erinyes might be spotted catching a bird and eating it alive, PC's who witness this must make Horror checks, etc."
I loved that schtick, and used a modified version of it in my homebrew as the sole means fiends(and most celestials!) had to enter the material plane.
I was just wondering though, was transposition ever touched on in any other D&D product? OGL? Because a fully fleshed out chart for all the fiends is something I'd love to see. Or make, if need be.
