Realm of Torment

The Realm of Torment is a region featured in the Nightfall campaign, but it is not located in Elona itself, but in the Mists, accessed through a portal in Elona.

Supposedly, the Realm of Torment is the realm of Abaddon, the fallen god. He was exiled to this place by the five Gods of Tyria. From here he seeks to gain back control and spreads evil into the world of the mortals, eventually trying break from to his "prison cell".

To stop the Nightfall, players have to venture into this most hazardous area to defeat the evil forces.

It is revealed by the Reaper of the Bonepits in the Underworld that the Realm of Torment is a division of the Underworld where the most wicked go to spend eternity in torment. From this it can be inferred that Shiro Tagachi has been sent here from what Kuunavang says at the Divine Path once you have beaten Guild Wars: Factions. This has not been confirmed by any source, though, and is purely speculation.
