Quick summary of Eberron’s planes

According to arcane scholars and sages, Eberron has 13 outer planes of existence. The vast majority of people have never visited these alternate planes, but their lives are touched by them nonetheless; the planes have two particular properties that allow them to affect the material world on a regular basis.

First of all, the planes have what are essentially orbital periods; every so often, a given plane will become close to Eberron, referred to as “coterminous,” and Eberron will start to reflect its nature to a greater extent. For example, every 5 years, the fiery plane of Fernia draws closer in its orbit, and fires all across the world burn brighter and hotter, and volcanic eruptions happen more often. Likewise, the plane will then draw far in its orbit, and its influence will be felt less often.

Secondly, many regions of the world are “manifest zones”, areas that are permanently close to a given plane and reflect its attributes all the time.

The Relevant Planes So Far

  • Mabar, the Endless Night, is a region of shadows and negative energy that is very similar to the Shadowfell as described in the regular D&D books. Mabar was very recently coterminous for the first time in 5 years, and the rakshasa’s actions in Korth have turned a large portion of the city into a manifest zone of Mabar, suffusing it with shadow.
  • Lamannia, the Twilight Forest, is a region of raw, untouched nature. The first goblin crypt that the party visited near Sigilstar, Thrane, was in a manifest zone of Lamannia, and the party accidentally wound up in the plane on their way out of the crypt.
  • Kythri, the Churning Chaos, is filled with twisting and changing pockets of energy and elemental fury. It defies attempts to study and understand it, and has no predictable orbital period. It takes concerted effort and will to impose a state of consistency and steadiness on Kythri; it seems that the randomly-repeating chambers found in the depths of Ghaash’ta Hall were the result of Kythri’s influence.
  • Thelanis, the Faerie Court, is a more fanciful and magic-infused realm than Lamannia, and it is from here that many fey creatures come. Eladrin, such as Redbors and Guluvan, claim this plane as their native home.
  • Others: Sharn is built on a manifest zone of Syrania, the Azure Sky, which enhances flight and levitation magic and is the reason the towers in the city can be built so high. The elven city where Redbors learned to be a cleric is a manifest zone of Irian, the Eternal Day (the opposite of Mabar), which has allowed the elves to keep their ancestors awake in undeath for thousands of years. The remaining planes are Fernia, the Sea of Fire, Risia, the Plain of Ice, Dolurrh, the Realm of the Dead, Dal Quor, the Region of Dreams, Daanvi, the Perfect Order, Xoriat, the Realm of Madness, and Shavarath, the Battleground.
