In some recent publication (possibly a pre-order PDF, not sure), I saw a list of all other Icons mentioned in the various books. For example the Oracle, the Fool, the Alchemist, etc.
I know I saw this list, because I had forgotten about the mention of the Fool in the description of the Priestess, until reminded by this article. However, I absolutely cannot seem to remember where I saw the list, nor find it again. Does anyone happen to know?
