Well, we were supposed to think of Sylvia and Korob as magical for a bit. Happy Halloween peeps! Even Merlin speaking Latin and causing something to occur might simply be called advanced energy-matter manipulation. Who's to say words aren't a kind of super-high-tech key? (as some have seen with the Carrionites in Dr. Who's "The Shakespeare Code"). Clarke's third law makes as much sense in reverse as forward: Any magic is indistinguishable from sufficiently advanced technology. Meaning that since we're used to tech being omnipresent in Trek, it's the reverse interpretation that is more often in play.
