They are done except for the product pages for the marketplace. Over 80 hours have gone into Island at the Axis of the World, the Player's Guide, and the Campaign Guide, and I have developed some great new techniques in Roll20 along the way, including allowing you to read each adventure or guide like a book from the external journal, so you can even read on your mobile device if you are so inclined.
The Campaign Guide comes with maps of Lanjyr, Flint, Central, and the RHC headquarters in case the GM wants to come up with other story elements along the way for side quests or roleplay.
The Player's Guide is already accessible to the player's when added to a game. This includes a dramatis personae folder of ~100 major NPCs the players will meet throughout the campaign. These have pictures and information for the GM and come with a token so the GM can drop an image on the page when needed, but the stat blocks on these are blank to not give anything away. The players can see information on NPCs they would know at the beginning of the campaign, and the GM can make more handouts available as they meet new NPCs. The players can keep notes on these NPC handouts, separate from the GM-only information. 40 additional NPCs are "red herrings" that the GM can use to create new NPCs on a moment's notice, and the players won't realize that it is not a "real" NPC.
Island at the Axis of the World has 32 handouts of art and information to show to the players as the adventure progresses. The three towers puzzle can be manipulated directly by the players. The Hedge Maze map has adjustable Dynamic Lighting lines; you can actually resize the lines if the PCs start burning portions of the maze.
Once the images for the product pages are captured, these will be submitted for approval.
