LORD TEDRIC _By Edward E. Smith, Ph. D._ _Illustrated by Lawrence_ Time is the strangest of all mysteries. Relatively unimportant events, almost unnoticed as they occur, may, in hundreds of years, result in Ultimate Catastrophe. On Time Track Number One, that was the immutable result. But on Time Track Number Two there was one little event that could be used to avert it--the presence of a naked woman in public. So, Skandos One removed the clothing from the Lady Rhoann and after one look, Lord Tedric did the rest! _Skandos One (The Skandos of Time Track Number One, numbered for reasons which will become clear) showed, by means of the chronoviagraph, that civilization would destroy itself in one hundred eighty-seven years. To prevent this catastrophe he went back to the key point in time and sought out the key figure--one Tedric, a Lomarrian ironmaster who had lived and died a commoner; unable, ever, to do anything about his fanatical detestation of human sacrifice._ _Skandos One taught Tedric how to make one batch of super-steel; watched him forge armor and arms from that highly anachronistic alloy. He watched him do things that Tedric of Time Track One had never done._ _Time, then_, did _fork. Time Track One was probably no longer in existence. He must have been saved by his "traction" on the reality of Time Track Two. He'd snap back up to his own time and see what the situation was. If he found his assistant Furmin alone in the laboratory, the extremists would have been proved wrong. If not...._ _Furmin was not alone. Instead, Skandos Two and Furmin Two were at work on a tri-di of Tedric's life: so like, and yet so wildly unlike, the one upon which Skandos One and Furmin One had labored so long!_ _Shaken and undecided, Skandos One held his machine at the very verge of invisibility and watched and listened._ _"But it's so maddeningly incomplete!" Skandos Two snorted. "When it goes into such fine detail on almost everything else, why can't we get how he stumbled onto one lot, and never any other, of high-alloy steel--chrome-nickel-vanadium-molybdenum-tungsten steel--Mortensen's super-steel, to be specific--which wasn't rediscovered for thousands of years?"_ _"Why, it was revealed to him by his personal god Llosir--don't you remember?" Furmin snickered._ _"Poppycock!"_ _"To us, yes; but not to them. Hence, no detail, and you know why we can't go back and check."_ _"Of course. We simply don't know enough about time ... but I would so like to study this Lord of the Marches at first hand! Nowhere else in all reachable time does any other one entity occupy such a uniquely key position!"_ _"So would I, chief. If we knew just a_ little _more I'd say go. In the meantime, let's run that tri-di again, to see if we've overlooked any little thing!"_
