As promised earlier, the now separate appendix to the CH manual has been updated and released. It contains info on the workings of the thieves guilds and marketplace exchange rates, as well as other things get it here.

Work on this appendix begun before the release of the manual approved by Ubisoft, but seeing as the authors of that are able to get their info directly from Ubival, we won't be continuing to update ours. Instead, we will be focusing on other ways to improve the Heroes V experience.
