Ever wanted to simply mess with your players? Here's an item that will have them looking every gift horse in the mouth from now on.
A fine brass ring adorned with the figures of pigeons and doves.
A seemingly helpful ring with harmful effects. Not the best of party favors.
Seven more magical rings, each with a very different enchantment on it.
You begin to feel funny. Your head becomes clouded as you approach the evil wizard. Wait, you shouldn't attack the wizard. He's done nothing wrong to you. Your party members are wrong. They lied to you. You should attack them!
...You come to your senses after a momentary black-out. You have blood on your sword. The bard is bleeding and the rest of your fellow party members have their weapons drawn and are poised to attack you. And you can hear the evil wizard behind you chuckling.
Seven rings were made long ago in the days of the Queens of old, seven highly magical rings to help a ruler to rule, but they proved anything but helpful.
Five crowns were created to bind together five regions into a single powerful kingdom, while a sixth crown was created to control the five.
Pity that someone went and destroyed the Crown of Crowns
With triumph the Halfling thief pried the shining silver circlet from the skull of some poor merman long dead of the trident plunged clear thru the bones of his chest. As he swam to the surface he marveled at the craftsmanship and planned to take it straight to the camp. That thin fidgety wizard, Prinny the Prestidigitator, might know the worth of this silver circlet with waves so detailed he could almost feel the call of the sea....
A piece of an ancient way of life, a tool for a consummate hunter.
"As he said this he blessed them with his amulet that held the Firestone, which is called also Seenu's Eye. Immediately the priestesses began to praise Tinay, and the people were greatly amazed."
- The Gospel of Dorcas, 7:20-21
Bluest of sapphires; the ice-cold jewel. From its hoary breath flows the bitter winter winds. The Lady Karina sits there for all eternity, looking deep into the eyes of her lover.
An ancient pocket watch grants its possessor sway over time itself, granted, at heavy price.
The perfect ring for those who seek to make the most dramatic of entrances.

Ah, you are awake now I see. Wondrous news. I realized that you have no idea what is transpiring so I will be blunt so you may understand it. It is rumored that you are one of the best jewelers and metalsmiths in the region and for that you are lucky enough to have been chosen to create an item that will change the world. And afterwards, you shall be set free. My word on it.

Gather your hatred about you, and master it, my brothers. It is the strength behind your shield, the speed of your blade. Do not abandon it, for without it, you are empty indeed.

A tiny ampoule of steel and old, clotted blood, hung from a black iron chain, the Amulet of Dark Valor holds the drive of the furies.
When you sleep, your soul briefly returns to the place where it was created/goes to when it dies, and seeks nourishment. Everybody's soul is created with a little link (or you could say a greater entity calls it back) to that place so that it can return easily, but upon death, the soul returns via that and annihilates the link as if returns.
Also, as an added thingy, you could say the entity supplying the link, or residue of the links themselves, (whichever) is the source of all arcane power.
