General Purpose Sourcebooks

Title Description Version
Directive Deck A guide for generating vague, possibly conflicting orders from a detached organization. Uses a deck of 52 playing cards, and lots of imagination. v1.1
Adventure Scene Tables This was originally some random tables for minor things that could happen in a fantasy setting. I think I originally made this as part of some community project. As of the 1.2 update, I've added several new tables, and expanded the types of tables. Thus, Fantasy was dropped from the title. v1.2
Sneaking and Stealing Stealth Missions (I hate that term) failing because one person gets a bad roll? Try taking this sub-system for whirl! v1.0
Information and Investigation Wizards spend all their time in their towers researching magic, but there's a startling lack of sub-systems covering how to do that. So I made one myself. v1.0
The Leyak When I found this thing in the game Abiotic Factor, I thought "This is one of the most evil things you can put into a game." So naturally, I cooked up something for putting it into a ttRPG. v1.1
