Device of unknown construction originating from Jamala's planet. Legends of the cave-dwellers residing on this world held true to the belief that the technology would generate a shield encompassing a substantial region of the valley where the inhabitants dwell.

Two generators are required to create the sun shield. Upon activation each beam hones in on the other, draping the orange veil over the valley.
