This gemstone has lost its power
'They are jewels, fused with radium. You rub them with your thumb to make them glow, and rub them again, the opposite way, to extinguish them.' - Xuthal of the Dusk
The product of a science long vanished in the ancient past, these gems seem to glow indefinitely when activated. There is a cost, however, as those who use the Radium Gems seem to slowly lose their grip on sanity, whispering to themselves of green stoned cities and the nameless horrors that stalk them.
