The set after TFT turned out not to be Critical Shift as we had planned. Critical Shift was going to be a new starter set, but that fell through. We reorganized the design team, and decided to do a Western-themed set first, with the hopes that we'd still be able to do CS as a starter set.
So, we took some of the cards left from CS playtest, mixed in new Western-themed cards, and made Shurikens and Six-Guns. (Yeah, yeah, Shurikens are Japanese, and Shadowfist is primarily Chinese-based.)
The set was still set post-Critical Shift. The main story, which was never written, was more of the usual: bad guys try to Take Over the World, Dragons stop them, etc. IIRC, Braz volunteered to write it, but that didn't happen. This story intersects it slightly (technically just after the main story's end), and should tell you everything you need to know. (I never released it because I was waiting for the main story to be finished. You'd think I eventually would've figured out that that trick never worked.)
This story was an idea of Gavin's that we thought was pretty cool, so we tossed a few references into the set, but nobody actually wanted to write it. Eventually, I decided I was capable of it, and had some ideas about how the plot could work, so I took a shot at it. It also ended up providing some background on one of the random "what's their
story?" characters who occasionally pop up in Shadowfist sets, and some early setup for a future set's story, which will now never happen. I also wanted to work the set's Purists into it, just to provide some explanation for them, but they didn't have an actual purpose, so they didn't make it in.
This is the next-to-last piece I have, but the last one (the Critical Shift story) is a big one, and still unfinished, although I'm making good progress. (Especially now that I'm done with Portal 2.) It's broken up into six parts, but I don't want to post any until it's done, since I may need to make more changes to the early parts as the later parts develop.( The Ballad of Jia Baoyu )
