According to the Quellithulians, extra-planar creatures have begun appearing in the areas around the Ulteran Spires, but not in the physical plane. Rather, they seem to exist mostly in an alternate plane that borders Norrath's. These creatures are disrupting the Spire's ethereal threads, making repair of the broken Ulteran Spires difficult. The Quellithulians have asked that I seek out these creatures using a special device, and destroy them.
Destroy 9 extra-planar creatures using the Ulteran Displacer given to you by the Portal Warden. Look for the swirling portals from other quests. Click on the portal at close range to trigger the spawn.
