Shadeshine

The shadeshine was a stone that, after contact, would heighten one's senses to an extreme degree, turning some, like sight and touch, into transmitters as well as receivers. Whovever touched the stone could speed up the metabolism of other persons, heat up the space around him or her, thicken the air around him or her etc. But anyone who touched the stone would die within a standard year as his or her senses eventually become so sensitive to external stimuli that the person's body and mind couldn't stand it. The person would eventually die in agony, burned from within.

The monarchs of Ventooine, the Satabs, were in the possession of the only shadeshine known to exist in the Galaxy. Each year, the Satab would chose a successor to hand down the stone and go into suspended animation. Han Solo ended the tradition along with the rule of the Satabs by killing the last of them and destroying the shadeshine by throwing it into Millennium Falcon's thust tubes when he visited Ventooine during his smuggling days.
