Well, I'm playing through CTDS right now (remember I'm reviewing it), but Chocobo Fan is correct in that, for the most part, this fan fic will be based off the original translation. The main reasons for this are that I know the original translation better (having played Chrono Trigger for the SNES once a year for ten years) and also the compendium is based off the original (for the most part) meaning that if I want to look stuff up, it's easier to do it if I'm using the original translation.
I figured Swallow wasn't Serge's Swallow (considering the difference in appearance) but don't you think it's a reference? Maybe not. In any case, I don't know about Medieval Europe, but I know for sure that Samurai usually wore three swords of varying length. I'm pretty sure in Europe most knights carried ceremonial blades when they traveled, and used big-ass broadswords designed for bashing when they went to war. Of course, that's an oversimplification of the period, but I don't think they usually carried more than one sword.
As for dueling with two weapons, I hadn't thought about it, to be honest. I guess I just see Crono as a one handed kind of guy. Who knows, though? We'll find out in the next section.
