Item from The Wheel of Time by Robert Jordan
A twisted silver ring that allows a non-dreamwalker to enter Tel'aran'rhiod — dangerous for the untrained, invaluable for those who know how to use it.
The dream ter'angreal allows anyone who sleeps while touching it to enter Tel'aran'rhiod. Egwene used it to explore the World of Dreams before her Wise One training provided natural access. It's dangerous because untrained dreamers can be trapped, killed, or manipulated by stronger dreamwalkers — but it provides access to the most versatile scouting and communication tool in the world.
A ring of silver twisted into a shape that seems to have too many sides — looking at it too long makes the eyes water. It's small enough to fit on a finger and warm to the touch.
