I’ve put together a new info page to help people make sense of what’s going on in the various story arcs and how they relate to one another chronologically.
Check out the new Timeline.
The details on that page are subject to some small potential changes, but the dates should stay fairly consistent. Hopefully this will explain why Hide and Seek has ignored the events that took place during the three previous story arcs. But that doesn’t mean the arcs are completely unrelated! You’ll have to keep reading to see what I mean by that, of course. :)
