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. Whoever touched the stone could speed up the metabolism of other persons, heat up the space around him or her, or even thicken the air around him or her, along with other abilities. However, anyone who touched the stone would die within a standard year as his or her senses eventually became so sensitive to external stimuli that the person's body and mind could no longer stand it. The person would eventually die in agony, burned from within.
