Star Wars: Tapestry, Volume III
(Note: Each volume of Star Wars: Tapestry contains 500 in-character posts. However, due to a couple recent moves, Volume III has been broken into three parts: the first 108 posts have since been deleted from the Wizards of the Coast 'Star Wars' boards, but have been preserved and will appear in the complete Volume III pdf. The next 124 posts can be found here.
As of January 2014, this game has almost reached its conclusion (and is likely to slightly exceed the 500 post limit). After the final post is made, all will be combined into a proper pdf of the complete Volume III. And now, back to the story! :) )
