[Crash Ichimonji]

I see. My concern was I'd get too 'real' in an explanation and bog down the shininess of it all. In some of the Process-content stories I've read that involve science fiction instead of magic usually the catalyst for process is something that is intended for a less extreme scenario that ultimately snowballs into an extreme situation, like in an Evangelion AR fic where an artificial radiation-field that undoes damage caused by aging and oxidation accidentally hits Shinji and undoes years of aging until he's reverted to an infant. Stuff like that. I'm never fond of 'magic raygun to shrink people' stuff unless it's something like Wayne Szalinksi's shrink ray where it was supposed to be a long ways from being used on humans.

In short, I personally prefer the catalyst to be accidental (or misused by a someone against their rival).
