I'm quite interested, did devs actually make up some of the item descriptions? For example, the one for whispering snake-skull says:
"I, who had no hands, with my left hand do bring forth, an offering of filth and rancid flesh.", which is in iambic pentameter and is not googlable, and sounds rather nice.
Concordat of worms has the following description:
"I give unto thee true peace, and to all who are or have been on thy side in the time of this discord."
This one is taken from the historical document, http://en.wikipedia.org/wiki/Concordat_of_Worms
What are other examples that you noticed?
