OK, I can't recall how you run across this in the game, but here's what I found with IE:
Pendant of Yemeth
The Pendant of Yemeth is constructed of some silvery metal. Six crystals radiate from the skull in a circle, forming a crown of sorts. A leather lanyard is looped though an eyehole attached to the top of the skull.
The item is named for its creator, a sorcerer of a by-gone age. Though Yemeth's power was great, time began to take its toll on him; he began to grow weak and sodden. The Pendant was commissioned by the dying wizard to serve as a vessel for souls -- souls which Yemeth himself would draw from dying mortals, and later use to power his waning life-force. Yemeth was eventually slain in a battle, destroyed utterly, and the Pendant was lost. Sages said that, even if the Pendant were to be recovered, no mortal knows the secrets of its use.
Here's some other interesting items I found:
TOME O' CHEATS
This is the infamous Tome o' Cheats, a massive libram of sleazy little loopholes and the like written through the collaboration of dozens of dastardly power-gamers.
As soon as it's decided exactly how much of its possible functions can be implemented in the short amount of time we want to allot to it, you'll be able to cheat, cheat, *cheat* like mad with it. Hoody-hoo!

This unholy weapon is obviously intended for Quality Assurance to massacre any creature in their path as quickly as possible.
There's nothing a little poison
What happened here was the gradual habituation of the people, ... to receiving decisions deliberated in secret; to believing that the situation was so complicated that the government had to act on information which the people could not understand, or so dangerous that, even if he people could understand it, it could not be released because of national security.
