Mabar the Endless Night is a blackened realm where the faintest spark of light is quickly devoured by the unending darkness. It is a plane suffused with negative energy and the antithesis of Irian.[1]


Mabar is a realm where no light shines. It is a world that is home to demons and the creatures that go bump in the night.[1]

On Eberron, one can be brought back after death as either an undead or as a deathless. Those that are undead are said to have been infused with the essence of Mabar, while deathless have been infused with the powers of Irian. There are those that worship the deathless of the Undying Court who wish to remove all undead from the world. These Deathguards will hunt down Mabar manifest zones, trying to sever their connection with the realm.[2]

On the flip side, priests of the Blood of Vol will also seek out manifest zones of Mabar, to build shrines and allow access to more powerful spells. In addition, a sect of druids called the Nightwalkers also worship Mabar, and seek out manifest zones, especially the Gloaming.[3]

Mabar and Mabar manifest zones are also responsible for Mabar Crystals, inky black crystals that empower darkness spells.[1]


Manifest ZonesEdit

Effects on the Material PlaneEdit


The nights grow blacker and more dangerous when Mabar becomes coterminous with Eberron. Travel to Mabar becomes as easy as stepping into an area where there is no light, and inhabitants of the plane slip out from the shadows and into the world. The plane becomes coterminous on three dark nights in the dead of night on the nights of the new moon closest to the winter solstice.[1]


When Mabar is remote, the darkness seems to sap from Eberron. These periods occur every five years on the nights of the full moon around the summer solstice.[1]

Notes Edit

Keith Baker has suggested on his website that Mabar is misunderstood as the plane of darkness, while it really symbolizes all things succumbing to death and entropy, even hope and light.[9]
