Forgelight

Description
When this weapon was forged, it was left too long in the coals, becoming super-heated until it glowed a fierce, white-gold.

Once it was cooled and fitted, the new owner noticed that it still glimmered in the darkness, even when there were no other lights around. Unfortunately for the owner, who was a footpad by trade, the light interfered with business that is mostly done in dark alleys. The weapon was quickly sold on, and has changed hands dozens of times, yet it still maintains its glow.
