The Glow Lights of the Great Library. This set of five unbreakable crystal balls provide bright magikal light so people can read among the rare books and scrolls in the Great Library without risking candles. These innocuous items are often overlooked. They would not be, if anyone knew their origins were with Corvus the Mad.
The Dragon Carved Egg, is a perfect crystal egg, the size of a goose egg, etched with images of a pride of dragons. It grants the one holding it immunity from Dragon. This item is another Legacy of Corvus the Mad. In fact, his signature is written in tiny script in the edtchings.
Arune Spheres are hollow, blue reflective metallic spheres about 25 cm/ 10" in diameter (though some are larger). They are made of a thickish glass mirrored on the inside. When magical energies are flowed through the sphere, it produces a haunting tone, which can be varied by the type, intensity, and harmonics of energies passed through it. (It sounds like an electronic organ.) If multiple energy flows are generated, multiple sounds can be generated, some of which sound like mundane instruments. Masters of The Craft can replicate almost any sound in their memory with one. Though originally used as a training tools for those with The Power, it has been adapted to be a musical instrument. All it takes is someone with patience, medative training, and a touch of the Power, to use it. (Thus becoming the favorite instrument of anyone who was tested to the first level of the Craft, but failed to advance).
