During The Golem, the player discovers the only portal to the throne room under the ruins of Uzer. The Elder Demon Thammaron laid siege to the city during the God Wars, and opened the portal inside the city to bypass its defences. Although Uzer is destroyed, Thammaron eventually succumbed to his wounds, and his skeleton could be found in the throne room. The player reprograms the clay golem found in Uzer to make it believe its task of slaying the demon is complete.
During Shadow of the Storm, the player infiltrates a demon-summoning group only to discover Denath, a member, is actually the demon Agrith-Naar and tricked them into de-summoning him back into the Infernal Dimensions where he would be more powerful. The player regroups the rest of the team, recruits several more unlikely people, and finally defeats him after re-summoning him into Gielinor.During Do No Evil, Eruni, a demonic ape capable of summoning lesser demons created by Amascut with Apmeken's stolen hearing, resides in this realm, but the player finds and defeats her.
