“Read the card to the end. Then read it again, and this time believe it less.” That is how basic training in the Investigation Branch begins, and it is how volume 22 begins.
The Registry is O.D.I.N.’s card index. The book opens it to the Game Master: 105 beings from nine origins, from the Voice to the Thoughtforms, each on three pages. At the top is what the Registry believes, in the middle what the agents learn from the knowledge test, at the bottom what is really true. Every card is wrong in at least two places, and one of those mistakes can get a cell killed.
Added to that are stats following the Core Rulebook, subtypes with a case of their own, the cover-up and six hooks for each being. The appendix holds registers, a D66 encounter table for each origin and a blank index card for your own beings. 390 pages, in English and German, free.
