The Iron Horse: Timeline through Ch. 22 · 12:54pm Sep 9th, 2015
Recently, alert reader JFalk asked about the timeline/timeframe of events in the story so far. So, here's a brief little morning post to discuss it!
Keep in mind, if you are NOT caught up on the story, there will be spoilers about events. If you're caught up to the most recent chapter, "Rhinestone Eyes, Part 1," then you're safe.
Also, I'm happy to say that the next chapter has been written and is being edited and a new illustration for it is being drawn. You can probably expect it this Sunday. 
On to the timeline!
