Umbra
The land of darkness and chaos., created by the dark goddess Shaltha in mockery of her sister's efforts to form the Lúmiriel, the Song of Light. By siphoning off the power of the Lúmiriel to create her own realm of power, she distablised the rings. As planes of existence collided in the event known as the Confluence of the Rings, the Umbra was forced into existence.
