Dimensional Seal

A dimensional seal is a minor artifact and magical site that seals off a manifest zone. The Gatekeepers used dimensional seals to sever the various manifest zones to Xoriat at the end of the Daelkyr War.
A dimensional seal is a massive slab of stone adorned with an intricate pattern of runes and sigils.
Locations
Such artifacts are commonly found in the Eldeen Reaches and the Shadow Marches, where they are remnants of the war the Gatekeepers and the daelkyr. Cults of the Dragon Below often try to break these seals.
Notable Dimensional Seals
A dimensional seal sits beneath Yarkuun Draal, though it has been partially corrupted by the daelkyr lord Bhodex'av'gr.
A dimensional seal sits beneath the Bonetree Clan of the Shadow Marches. The dragon Dah'mir attempted to breach this seal.

Mechanics & Inner Workings

A dimensional seal has two major properties. The first is that it projects an unseen magical field preventing effects such as teleportation, planar shifting, summoning, or dimensional travel, similar to the dimensional lock spell, up to a distance of 2 miles (3.2 kilometers).
The second is that it nullifies the effects of a manifest zone within its field, thus negating its influence upon the Material Plane. Destroying a dimensional seal will restore its effects.[1][6]
In addition, the placement of these seals disturbs Xoriat's orbit in the Astral Plane, preventing it from again becoming coterminous with Eberron.

History

Last fashioned over 9000 years ago, the secrets of creating dimensional seals have been lost to time, though it is assumed that the knowledge originated with the dragon Vvaraak, the mentor of the first Gatekeeper druids. The goblins of the Dhakaani Empire tried to duplicate their magics, and an artificer named Taruuzh came close with his binding stones, but even he could not duplicate the dimensional seal.
The Gatekeepers began placing these seals throughout the Shadow Marches and Eldeen Reaches towards the end of the Daelkyr War, after combined orc and goblin forces pushed the daelkyr armies back to the plane of Xoriat. The seals severed ties with the Realm of Madness, preventing the daelkyr from returning to Eberron.
Since the dimensional seals were created nine thousand years ago, though, their magics have been slowly deteriorating. The Gatekeeper druids have been tasked with maintaining their magics; but the Gatekeepers' numbers grow smaller and smaller each year. Now, an estimated thousand Gatekeepers are spread across the Eldeen Reaches and the Shadow Marches. While the Gatekeepers have the ability to temporarily generate the effects of a dimensional seal, they do not have the abilities to recreate the artifacts.
