Into the Wardrobe

For awhile there, with the Tom Bombadil so-called "heresy" and others, I thought you were losing your touch, Erekose. But perhaps you were just tired.
Good to have you back in all your insane, heretical glory!
This last heresy made no sense whatsoever! Good job! ;)

Strangely, my "Unified Grand Heresy" has more of a Fantasy touch to it than Science Fiction, as would be apparent if I were ever to have the nerve to collate it into a single (though large) scribbilings.

To return to the question of the sewing machine and mechanics, there is actually a parralel in Prince Caspian.
At the end of that book, Edmund is somewhat aggreived, because he realises that he left his tourch behind.
If it had ever been written in a book that came "after PC" but was written before "PC" (sorry if thats confusing.. i.e. non-chronological order), would it have been assumed that narnia had developed the physical science to make such a device?

Personally, one of the reasons behind my "Grand Unified Heresy" is that the idea that there is a "causality" in the form of the Royal House of Charn" continuing, and being instrumental in repairing the damage done by one of the members of that line appeals to me.
