Rings of arbitration

Rings of arbitration are a pair of rings crafted for lovers who are bound body and soul. They are both a blessing and a curse because through the power of the rings a burden, such as drain of life-force, is shared between the wearers. The rings were created long ago by magic long lost to the world and only a few pairs exist. They are gold bands with a clear gemstone set in each which reflects the condition of its wearer - turning to black when that person's energy or life-force nears its end.
