The Empire of Light
Elfator means “The Future Place” in Elvish. The future means here “beyond death”. It is associated with West the direction of Sunset. These are the planes where a creature of The Spark, or more properly a “Guangren”, go to their final rest. It is also a place where beings known as devils, demons and celestials normally reside unless they for some reason come to Elantor.
