Dal Quor is a plane of thought, that mortal minds project into when they dream. The plane is home to the Quori, living psychic embodiments of dreams and nightmares.

Coterminous: Last time Dal Quor was coterminous, the Quori attempted to invade the giant empire on Xen'Drik. The giants fought back by breaking the connection between Dal Quor and Eberron. Since then, the plane has never been coterminous.

The Sovereign Host is the dominant religion of Khorvaire. Worshipers are called "vassals" and typically worship the pantheon as a whole rather than the deities individually. Their pantheon includes nine gods:

• Arawai, the Sovereign of Life and Love

• Aureon, the Sovereign of Law and Lore

• Balinor, the Sovereign of Horn and Hunt

• Boldrei, the Sovereign of Hall and Hearth

• Dol Arrah, the Sovereign of Sun and Sacrifice

• Dol Dorn, the Sovereign of Strength and Steel

• Kol Korran, the Sovereign of World and Wealth

• Olladra, the Sovereign of Feast and Fortune

• Onatar, the Sovereign of Fire and Forge

The Dark Six are a pantheon of six gods cast out of the Sovereign Host in an event known as The Schism. While the Sovereign Host represent positive aspects of life, the Dark Six represent forces of nature that people typically shun and fear. While dedicated worship of the Dark Six is taboo across most of Khorvaire, worshipers of the Sovereign Host will often pray to members of the Dark Six in an attempt to avoid their wrath. As the name suggests, they recognize six gods:

• The Devourer, Sovereign of Wave and Whelm

• The Fury, Sovereign of Rage and Ruin

• The Keeper, Sovereign of Death and Decay

• The Mockery, Sovereign of Betrayal and Bloodshed

• The Shadow, Sovereign of Magic and Mayhem

• The Traveler, Sovereign of Chaos and Change

The Silver Flame is the quintessentially pure abstract deity of goodness and law. It was supposedly born during the Age of Demons, when the couatls combined the souls of their race into a spiritual force powerful enough to bind even the demonic Overlords. The Church of the Silver Flame is the state religion of Thrane, but has followers across Khorvaire.

The Blood of Vol is an idiosyncratic and decentralized religion that worships the 'divinity within,' rather than an external higher power. Worshipers are known as "Seekers," short for "Seekers of the Divinity Within." They teach that other faiths are lies, that if the gods exist then they are cruel, that death is oblivion, and all we have is our life and each other - so make it count.

On the continent of Aerenal, the lines between life and death are blurred, and the living converse freely with the dead on a daily basis. The elves who live here do not pray to distant gods, but pay respect to their individual and common ancestors. The combined spiritual power of the deceased ancestors of the Aerenali elves makes up the Undying Court.

The Keepers of the Past are an elvish faith that has split off from the Undying Court. In regions which follow the religion of the Keepers, each adult member of the church is ceremoniously chosen by an ancestor spirit, who becomes that person's guide and guardian.

The Cults of the Dragon Below are not a unified religious doctrine. Instead, this term encompasses all religions that worship the progenitor dragon Khyber or any beings tied to her. These cults find their strongest worship in the western regions of Khorvaire, especially in the Shadow Marshes.

The Path of Inspiration is the state religion of The Unity of Riedra, and the faith forms the backbone of their nation. The main precept of their faith is that devotion to the Quori comes first and foremost. They believe these great spirits are opposed by evil gods and fiends, and that those who obey the will of their masters can be reincarnated into more and more powerful forms, eventually joining the Quori.

The Path of Light is a religion practiced primarily by kalashtar. It is most prevalent in Adar, in the southeast of Sarlona, but many kalashtar across Eberron belong to this religion. Those who follow the Path of Light believe that a powerful force lies at the heart of the plane of Dal Quor, and that they can help bring about a shift in that force to usher in a new age of the Dreaming Light to banish the current age of nightmare.

The Lord of Blades is an enigmatic figure who rapidly rose to power in the Mournlands. Some speak of him as a scholar and philosopher dedicated to the liberation of the warforged race, while others perceive him as a power-mad tyrant hell-bent on the destruction of the "fleshborn" races. Either way, one thing is clear - he has many zealous warforged worshipers who wander through the Mournlands, acting in his name.

The Becoming God is a very recent religion invented by the warforged following the Last War. With no claim to a religion of their own besides the Lord of Blades, some warforged have begun a pilgramage to create their own god - by building one. Devoted warforged scavenge for parts and holy relics across Khorvaire, in the hopes of eventually coming together to create a deity of their own.

There are a number of Druidic sects across Eberron, each with their own specific beliefs and traditions. Anywhere the wild calls, one can find druids of any species. Druidism is common among the lizardfolk of Q'barra as well as among the fey in Thelanis, and even the drow among the ruins of Xen'drik hold on to some ancient druidic traditions.

Regardless of their differences, most druidic sects share one belief in common: that the power inherent in the bond between the bodies of the Progenitor dragons should be used to protect the natural regions of the world from destruction and corruption.

Khorvaire is the most diverse and advanced continent on the planet. The Last War, the greatest conflict seen on Eberron in a long time, was fought between the nations of this continent when the Kingdom of Galifar collapsed. While the borders are still disputed despite the current peace, the continent's many large cities are home to numerous different species and cultures.

Aerenal is an island continent primarily occupied by elves, having settled here over 20,000 years ago when the giant nation of Xen'drik collapsed. Aerenal is its own nation, and is overseen by the Undying Court. Devotion to one's family is an extremely strong cultural ideal in Aerenal, being the central focus of their religion. The elves here pray not to the gods, but to their own ancestors.

Xen'drik is the homeland of the giants, who built one of the most powerful civilizations in Eberron before the continent was devastated in a war between the giants and the Quori. This war also severed the plane Dal Quor from the material. The giants attempted to rebuild after this war, but a combination of slave revolts and an invasion from the dragons of Argonnessen brought the last remnants of the giants' once great empire to its knees. Now, the continent is sparsely populated by various races, and is nigh impossible to navigate. Some adventurers refer to a "Traveler's Curse" that makes Xen'Drik supernaturally hard to explore.

Sarlona is the continent from which humans and kalashtar originated, though the continent is home to quite a few other peoples. The majority of Sarlona is ruled by the Unity of Riedra, which is controlled by the Quori. While various tribes and city-states dot the uncontrolled areas, the only real opposition to Riedra's vast empire is the small mountain enclave of Adar.

Argonessen is the home of the dragons, and is the oldest known civilization in the world. The continent is almost totally unexplored by outsiders.

Everice is a shifting sea of ice covering Eberron's south pole. It is said that several large land masses exist beneath the ice, though none who have gone seeking evidence have ever been seen again.

Frostfell is a frozen wasteland covering the north pole of Eberron. It is extremely cold, with numerous manifest zones connected to Risia, the Plane of Ice.

Khyber is a massive subterranean realm beneath the surface, said to be the the remnants of the body of the Progenitor Dragon of the same name. The upper layers are traditional caverns made of stone and dirt. However, the lower levels link to a vast array of demiplanes with all sorts of strange contents. Khyber's residents include fiends, aberrations, extraplanar creatures, imprisoned demons, and many other monsters.

Aundair was the northwest region of Galifar before the Last War. Although much of its western forest territory has now gained independence, becoming the Eldeen reaches, Aundair still possesses swaths of fertile fields that supply the nations of Khorvaire with good and fine wines, while large universities produce scholars and knowledge.

There is a sharp split in the population of Aundair between rugged agriculturalists and learned scholars. Either way, Aundair has a strong culture of competition and stubbornness, and public duels have become a staple of their society.

Breland was the southwest region of Galifar before the Last War, and now is one of the largest of the remaining nations/territories. Breland is a mix of open farmland, woodland, and sprawling metropolises - the largest and most famous of which being Sharn, the City of Towers.

Sharn is the largest and most populous city on Khorvaire. It looms atop the cliffs overlooking the 'Hilt' of the Dagger River.  The city has no room to expand outwards, so it expands upwards - in some areas, the towers reach over 1 mile tall. They stay upright predominantly due to the fact that Sharn is built in a manifest zone linked to Syrania, The Azure Sky.

Sharn is the most racially and culturally diverse cities on Eberron. Some describe it as practically an entire nation in and of itself.

Karrnath was the northeastern region of Galifar before the Last War. The nation is particularly noted for its widespread use of undead soldiers during the war, and the ruthless dictatorship of its monarch and royal family. Being covered in vast and dense forests, wood and paper products are Karrnath's biggest export.

One of the oldest human nations on Khorvaire, Karrnath was built on strong military traditions, which carry on to this day. Every Karrnathi citizen is forced into compulsory military service for at least two years as soon as they come of-age. While some restrictions have been lifted after the Last War, martial law remains in place to this day.

Thrane is located in central Khorvaire, between Aundair and Breland. Both Karrnath and the Mournland now border it on the right, though this was not the case pre-war in the kingdom of Galifar. Thrane is notable in that it has replaced its monarchy with a theocracy. Unlike most nations on Khorvaire who worship the Sovereign Host, Thrane's state religion is the Silver Flame.

Thranish culture is conservative in that they are devoted to religion, family, work, and their puritanical ideals. Thranes are hard-working, and once they accept a task, they devote themselves to its completion. Despite common belief, however, the majority of common Thranes are not zealots, and are at least somewhat tolerant of all religions.

The Demon Wastes are a wasteland in far far northwest corner of Khorvaire. Tribes of human, tiefling, and orc barbarians eke out a living here between regions of mountain, badlands, and plains.

The Eldeen Reaches are a forest-filled landscape in northwestern Khorvaire. They used to be part of Aundair before the Last War. While some cities have formed around the borders of Aundair and Breland, most of the territory is inhabited by various druidic sects or agricultural groups.

The Shadow Marshes are fetid blackwater swamps at the western edge of Khorvaire. Orcs make up most of the population, and they have a reputation for xenophobia. Outsiders are rarely welcomed.

Droaam is a nation ruled by monsters, established a decade before the end of the Last War. The area is nigh inhospitable, being mostly barren plains. Few of the "civilized" races dare to test its borders. As low as it is in arable land, however, it is high in mineral resources.

Zilargo is a gnomish nation on the southern coast of Khorvaire. It was once a province within the Kingdom of Galifar, but became an independent nation once again upon the signing of the Treaty of Thronehold. The nation is best known for its national newspaper, elemental bindings, bards, the Korranberg Library, and their diplomatic expertise.

Darguun is a nation that broke off from Cyre during the last war, when goblinoid mercenaries seized the region for their own. The region has become a host for many members of their race seeking a homeland, including hobgoblins and bugbears.

The Talenta Plains are a large grassland stretching from the Blade Desert at its eastern edge to the borders of Karrnath and the Mournland. It is the home of wandering herds of buffalo-sized dinosaurs and tribal halflings remaining true to their ancient nomadic way of life.

Before the Last War, the area was split between Karmath and Cyre, but during the war, the halfing tribes united to drive back the forces of both nations. At the treaty of Thronehold, the tribes presented a united front and were granted their autonomy.

Valenar is a nation that broke away from Cyre during the Last War when the elvish mercenary group called the Valaes Tairn claimed the land for themselves. Refugees fleeing from Cyre after the Mourning that attempted to seek asylum in Valenar were mercilessly slaughtered out of fear that they would overwhelm the mercenaries' claim to the region.

Q'Barra is a temperate region on the southeastern corner of Khorvaire. While Cyre attempted to explore and settle the region, the few dots of human civilization pushing into the edge made little progress through the steamy jungles and sprawling swamplands, especially with the native lizardfolk defending their home.

The Mror Holds are the homeland of the dwarves. The region is relatively small, but the 12 clans are incredibly wealthy, and that wealth buys quite a bit of political influence. They declared their independence from Galifar near the start of the Last War, but it was only officially recognized with the Treaty of Thronehold.

The Lhazaar Principalities is a country comprising a small strip of land on the northeastern coast of Khorvaire, as well as a collection of islands nearby. Pirates, sea barons, merchant traders, and all others with a love of sailing find their home here.

House Cannith is known primarily for their innovations and advancements in technology. During the Last War, they gained monumental amounts of political power by selling weapons and warforged soldiers to all five nations. However, after their leader and his appointed successor died in the Mourning, the house split into three separate but close factions: 

• Cannith South, based out of Sharn in Breland

• Cannith West, based out of Fairhaven in Aundair

• Cannith East, based out of Korth in Karrnath

House Deneith was once just a militant noble family in northeastern Khorvaire, until they developed their dragonmark. With the mark of sentinel, they waged a campaign of conquest throughout the region now known as Karrnath. During the Last War, House Deneith refused to take sides despite their close connection to the government of Karrnath. It instead earned its status as a mercenary house by offering soldiers to all nations for hire.

House Jorasco runs the Healers Guild, providing magical and mundane healing for those who can afford it at their hospitals and enclaves across Khorvaire. Members of the guild include herbalists, alchemists, physicians, as well as some clerics and adepts of the Sovereign Host and the Silver Flame. Few seek healing from the church, and only the most devout or well-respected within a religion will usually receive any healing from them. Instead, people go to House Jorasco to buy medicine and treatment.

During the Last War, House Lyrandar made their money primarily via targeted weather manipulation. However, as House Orien's trade network deteriorated, House Lyrandar picked up the slack with sea-based trade routes. Their true economic breakthrough came with the invention of the first elemental airships. No longer limited to the seas, House Lyrandar became a shipping powerhouse, with a massive fleet of airships on standby for hire.

While House Medani is currently the smallest existing dragonmarked house, they provide an immensely valuable service in many fields. Their members can be found seemingly anywhere, working as guards, advisors, researchers, inquisitives, and spy-catchers. Unlike most dragonmarked houses, House Medani almost exclusively operates out of Breland. During the Last War, they worked directly for the Breland government in counter-intelligence, though they never directly supplied infiltration services.

House Orien specializes in courier services and land-based travel. Although House Cannith invented the lightning rail, House Orien are the ones who operate and maintain the rails connecting the major regions of Khorvaire. House Orien was hit the hardest by the war, as their infrastructure was strategically destroyed by all sides in an attempt to slow down enemy advancements. In an effort to regain control, the house has begun to focus on teleportation business and research, though it remains too expensive to become mainstream as of yet.

To the public, House Phiarlan is a house of entertainment moguls, composed of bards, actors, artists, and acrobats. In secret, however, their specialty is spy work. During the Last War, they offered their infiltration services to all nations. However, this brought members of the house into a complex web of plots against each other, and this led to conflicting loyalties erupting into a civil war known as the Shadow Schism. As a result, House Thuranni was founded as a splinter group from House Phiarlan.

House Tarkanan is a criminal organization founded relatively recently. While it presents itself as being equivalent to the other dragonmarked houses, the other houses do not see it that way. House Tarkanan has a reputation for assassination, thievery, and other forms of organized crime. They will allow anyone with an Aberrant Dragonmark to join without question, but others have to prove their skill and loyalty first.
