The Underworld

The Underworld is the realm of Grenth. Many years ago, Dhuum, the cruel and unjust god of death who neglected his duties and enslaved the dead, was deposed here.

When the body dies, the spirit will be released into the Rift. These spirits will find their way to the Underworld, normally via the River of Souls. Here the spirits are led to their final resting place, depending on numerous factors, such as how they performed in life, how they died etc.

More recently, this realm has become infected with the memory of the fallen god of death. Mysterious forces have been intercepting the River in the Realm of Torment, before it even reaches the Underworld. Demons have appeared across the realm, terrorizing the dead. In desperation, Grenth has opened up his realm to Ascendants from the mortal world to help cleanse his realm of evil.
