You're not dumb, I'm just not very specific about the various props I'm making for the LARP, since they're so numerous and it woudl require me to explain the whole plot, which would take a looong loooong time.
Anyway, one of the characters will own a quite distressed copy of a Necronomicon. So that it's content can drive all the other characters into madness, gnak gnak ! *mischievious smile*
