- Ioun stones
Ioun Stones are magical items for the "
Dungeons & Dragons " role-playing system, which are based on similar artifacts fromJack Vance 's "Dying Earth series ". ["The idea and name for the "ioun stone" originally appeared in a series of books written by Jack Vance. Collectively, these works are referred to as the Dying Earth novels. They include: "The Dying Earth", "Eyes of the Overworld", "Cugel’s Saga", and "Rhialto the Marvelous"." (Hargenrader 1991, "Bazaar", p 90)]When functioning, they float in a circular pattern around their bearer's head, and grant various benefits based on their color and shape. Two stones of the same type will repel each other, and when drained of power, a stone becomes a dull grey, but still possesses the characteristic floating.In the original Jack Vance stories IOUN stones are highly prized by arch-magicians, and are acquired from a race known as the archveults, who mine them from remnants of dead stars (in his book "Rhialto the Marvellous"). In 2E "Dungeons & Dragons" it had been conjectured in "Dragon" magazine that Ioun stones instead come from the Positive Material Plane: however under the recent 3.0/3.5 editions of the rules they are instead manufactured by spellcasters in the same manner as other magical items.
In 4th edition, a deity named Ioun was introduced in the Player's Handbook.
