Desert Demon Quest Guide

To start the Desert Demon quest, you have to teleport to ::kril and walk through the city gates of Sophanem(slightly south of the teleport).

From there, you'll have to go further south and speak to an npc named "Urbi" to start the quest, you'll see quest icons on your minimap so it shouldn't be hard to find. They'll ask you to help them stop the evil wizard Darius.

Then you'll have to run North of Sophanem into the desert. This image will show you exactly where to go.

There will be a Dark Hole that you'll have to go down.

You'll find that you're now in a maze. Below you'll find a guide through it(Thanks to Primefire).

There you'll find the wizard Darius, talk to him, and he'll summon the demon Bal'lak the Pummeller. Kill Darius.

Then run north of him into the cave where you'll fight and kill Bal'lak The Pummeller.

Then just return to Urbi in Sophanem and complete the quest.
