This had me think for a moment, but wheelchairs will be hard to maneuver around the Fae Wild. There are paths to walk on during the Spring through Fall months, but they're all dirt paths. The only stone path is the one that leads from the forest to the village. So long as you don't mind her wheelchair being changed to one of those old-fashioned wooden ones with the large wheels, accommodations can be made by the Handmaiden and her helpers.

And, yes, the cyborgs will find themselves in fully human bodies (sorry Cylons). And characters with high-tech prosthetics will find themselves with magical replacements made out of wood and powered by magic.
