Antinomia: FF6

You can utilize some of the event code if you like, but be warned that it's a bit more expansive than it might look:

Thanks for the offer, but I will probably need to write my own events so that I can fit it into the right spaces in my rom. I'm more looking to use the idea.

Oh, sure, you can certainly use the idea since it isn't exactly "original"; it's just a depiction of a canon event that originally happened off-screen.  And you're welcome to use the "Piett" name, too, since, again, I already stole it from Chrono Trigger where he appeared alongside Biggs and Wedge, and all three of them in and of themselves are references to Star Wars side characters, so they're not "mine".  XD
