Fawn's Hebrew letter is pe (also fe), the Tower card, which usually displays a tower being struck by lightning and collapsing like the Tower Of Babel. As the Tower Of Babel is considered the source of the world's languages in the Bible, I felt it was appropriate to display it as a falling stack of books. This also works because pe is the Hebrew letter which matches the Latin letter P (print, pen, paper, press) and both are derived from the Phoenician letter pe, believed to have been a drawing of a mouth.
As there is no natural "j" sound in Hebrew, they improvise by using a geresh mark with a gimel. Convenient, then, since Gisele's name starts with G, one of two letters analogous to gimel, (the other being C.) This gives her the card of the High Priestess, often flanked by the Masonic pillars of Jachim and Boaz, shown here as bottles of alcohol. (J&B whisky, perhaps?) One can only imagine what sort of sect would put her in charge.
Another interesting Biblical/Dubmarine-related tidbit: Boaz was the husband of Ruth.
