Quick note from November 2017:
At this time, please disregard everything below until I have a chance to update the links. Pretty much all the chapters have new documents now.

Updated January, 2017
Here is a complete list of all chapters which are open for editing.
The goal is to do a detail pass for all of these except Portents of Darkness, which is already finished.

As chapter seven is the next to publish (on April 1), this should be the top priority. When it is finished, the prologue is next, followed by subsequent already-published chapters.

In April, once chapter seven is published, we should finish off chapter eight after that, and so forth.

Orion's free-edit doc is here. This is where the detailed writing will take place initially before getting copied into the links below.
