1) The PrintFriendly version should be as up to date as version v6-2-1. It went through viewer version iterations as the PrintFriendly option was implemented later. Both will soon receive their update.
2) The book has a rough reion map included in the first pages of the book! As for pre-made dungeons, while there are none in the book itself, I have a collection of free adventures set in the Soulblight setting, which can be found here and will soon also be uploaded here on itch.io as a properly layed out pdf! The update I am working on will also include random encounter tables tied to each of the seven regions. Already included in the book are small tables tied to each of the seven Sovereign's Shadowdark locations that may be used to generate ideas for a dungeon.
3) Yes, the printer-friendly version is composed of black letters on a white background!
