A magical crystal, sacred to the Light, the Sungem was prized from its home in an ancient monastery and turned over to the authorities in the Port of Glass. It was subsequenctly fractured (though not destroyed) in a ritual directed by Duke Karl, though the ultimate purpose of this was unclear.

When in the monastery the gem appeared to render the holy grounds invisible to those not blessed by the light. This ability was temporarily thwarted by a combination of vitirachal intervention and a partial eclipse.

What powers it has in its fractured state is unknown, save that study of the gem was able to let the sentient sentinel Daniel Kelson master a truly debased form of unordained Light magic.
