Radiance is the cold iron magical sword wielded by the paladin Yaniel during the Fourth Mendevian Crusade. Upon her death in 4694 AR, the sword's powers seemed to disappear. It was stolen from the Gray Garrison sometime in 4713 AR. The Templars of the Ivory Labyrinth are suspected in the theft.
Radiance's magical powers can be awoken when possessed by a paladin. If ever wielded by a paladin of mythic proportion, additional powers and abilities may be discovered within the sword.
