Description

The Eberron Material Plane is the central world of the Eberron setting, a unique cosmological structure distinct from other known multiversal configurations. Unlike many worlds where the planes are layered hierarchically, Eberron exists as a self-contained system surrounded by twelve orbiting planes of influence.

It is a world of ancient magic, elemental forces, and evolving civilisation, where arcane innovation shapes daily life and the boundaries between magic and industry are deeply blurred.

Overview

The Eberron Material Plane is characterised by:

• A vast, single shared world rather than multiple disconnected material worlds
• Cyclical alignment with surrounding planes
• High levels of magical integration into society and infrastructure
• Long-standing ancient ruins from lost civilisations

It serves as the primary stage for political, magical, and divine conflict within the setting.

Physical Properties

The world of Eberron resembles a conventional planet, but with distinct magical and planar influences:

• Continents such as Khorvaire, Xen'drik, Sarlona, and Aerenal dominate the globe
• Arcane technology, known as “magecraft,” is widespread
• Elemental forces are commonly bound into industry and transportation
• Natural laws remain stable despite high magical saturation

Planar Adjacency

Unlike many Material Planes, Eberron's is uniquely surrounded by twelve orbiting planes:

The Twelve Planes

Each plane has periods of influence when it becomes coterminous or remote:

• Dolurrh – realm of the dead
• Mabar – plane of darkness and entropy
• Irian – plane of eternal dawn
• Shavarath – plane of endless conflict
• Fernia – plane of fire
• Risia – plane of ice
• Kythri – plane of chaos
• Lamannia – plane of primal nature
• Syrania – plane of air and serenity
• Thelanis – realm of faerie and story
• Xoriat – plane of madness
• Dal Quor – realm of dreams

These planes periodically draw closer or further from the Material Plane, shaping magical and environmental phenomena across Eberron.

Magic on the Plane

Magic is deeply embedded in Eberron society:

• Arcane arts are industrialised and widely accessible
• Dragonmarked houses regulate and control major magical industries
• Elemental binding powers transportation and infrastructure
• Planar cycles influence spell effectiveness and availability

Unlike many worlds, divine magic does not require direct intervention from deities, whose existence is a matter of philosophical debate rather than confirmed presence.

Inhabitants

The Eberron Material Plane is home to a vast range of civilisations:

Major Civilisations

• The nations of Khorvaire
• The arcane traditions of Aerenal
• The psionic cultures of Sarlona
• The ancient ruins and mysteries of Xen'drik

Societal Structure

Societies are shaped more by:

• Dragonmarked Houses
• National alliances and political blocs
• Arcane industry and trade networks

Cosmological Role

The Eberron Material Plane functions as:

• The central nexus of a self-contained planar system
• A world shaped by interaction with orbiting planes rather than external outer realms
• A setting where prophecy, magic, and industry intertwine

It is considered unique among Material Planes due to its closed cosmological structure.

Variations by World

Unlike multiverse-linked settings, Eberron does not have multiple parallel Material worlds:

• It is a singular, isolated cosmology
• External planar travel is limited and highly controlled
• Cross-setting planar interaction is extremely rare or theorised

Planar Travel

Travel beyond the Eberron Material Plane is governed by strict cosmological rules:

• Passage occurs through planar conjunctions with the twelve orbiting planes
• Arcane ritual and dragonmarked infrastructure may facilitate limited travel
• Direct access to external cosmologies is considered unknown or mythological
