Mierest's Starlit Sphere

This item is said to have been created by the sorcerer Mierest and given to one of his visitors in reward for a great service. The shining silver metal sphere is 4 inches in diameter and feels comfortably warm to the touch. When held, it is lit with cold blue-white pinpoints of light, illuminating an area as a torch would. This ability can be turned off or on as a free action. The orb negates several spells by contact: dancing lights, darkness, faerie fire; gust of wind, light, and wind wall. Objects within the area of its light are viewed as if with a true seeing spell. If passed through an open flame, it chimes a soothing song for 4 minutes that can be heard up to 100 feet away and quiets shriekers. Intelligent undead prefer to avoid the area it illuminates but are not prevented from entering.
