Radium

Z: 88
Mass: 226
Lifeforce: Fire

An old alarm clock in a dark room, its numerals glowing faintly green. — Plate · Radium Radium made the dials glow, a *beautiful* shine that came at a price.

Active fire: drives outward, ignites change, gives generously. In its pure state, reacts violently. In balance with its receptive partner, becomes life-energy.

Born in supernova explosions, the death of massive stars scattering their innards across the galaxy.
