Hot off the Press! These are not your eldritch manuals or ancient folios of doom. These are random books, a GM can use whenever a PC reaches for a shelf, which usually happens when said GM is least expecting it. These can be found in most libraries, many private homes, and anywhere else one could expect to find a book. More than a few have some built-in plot hooklings as well, while others, like many books of our age, are plain drivel.
Just imagine a powder, that could make thing eatable (like swords or rocks).Try it an it will be verry funny.Just imagine..characters will need to get some information from someone. And if he will saw, as one PC is eating his sword.
