Interesting name. In Lord of the Rings the palantirs are crystal balls you can use to see what happens elsewhere, but after Sauron had gotten hold of some they had become more of a trap as the evil lord could get hold of the minds of people who used any of the palantirs after that. They also were always unreliable, as using them required extraordinary powerful mind and the ability to concentrate in order to direct their "seeing" to what would be useful instead of misdirecting the user to something that might give a false impression, or useless knowledge to him.
So, basically, the palantirs are something used by evil and useful only to evil.
