The Light Wall is the first barrier in a series that surrounds the fortress of Solangard and of their capital city of Solandyl.
Created from a series of enchanted crystals that the Hanabril call "Singing Stones " the light wall protects the elven kingdom from any light-sensitive creatures by projecting a curtain of sunlight from dusk until dawn.
The Light Wall, sometimes called the Sun Wall, is the outter-most wall of the defenses of Solangard matched with the inner 'Moon Wall " composed of Arcane Energy that protects the fortress itself.
