Though not technically a Realm of its own, the Nexus is a distinct plane of existence through which countless Realms can interact. Born from the Convergence, it is a physical dimension where unrealized possibilities can take form, reflecting the Realms not as they are, but as they could have been.

To those who enter it, the Nexus is a realm without ordinary geography or time. Its landscapes and inhabitants may be native to the Nexus, or manifestations of possibilities that never became reality.

The Nexus is more than a passage between Realms. What happens within it can influence established reality, allowing possibilities that never existed to become tangible and potentially alter the worlds from which they came.

Chaos

Chaos is the space between Realms. It exists beyond the Veil's boundaries of established reality, existing where the structures separating the Realms and the Nexus begin to break down. Ordinary distinctions of space, matter, time, and abstraction are increasingly unreliable within Chaos.

Whether it is a place, a state of existence, or something beyond either remains unknown. What is known is that it lies beyond the boundaries of what the civilizations of the Omnium can presently understand.

Karsina

The Realm of Karsina contains the planet Caldra; home of Mechanica, one of the great industrial civilizations of the Omnium. Unlike many of the known Realms, Karsina is consistent with conventional physical reality. Its worlds obey recognizable natural laws, and the forces that shape them can be measured and studied.

Through the study of Luminance, Caldra's Mechanica transformed a naturally occurring arcane energy into the foundation of an industrial empire, extending its influence far beyond what the Realm's inhabitants once believed possible.

The appearance of the Nexus has begun to challenge that certainty. What was once understood as a closed and predictable Realm is now connected to forces that exist beyond Mechanica's oldest assumptions about reality.

Jendarri

Jendarri is the Realm containing Veyruun, home to the peoples of Primal, as well as Centov, the homeworld of the Hadria Combine. Its planets are connected by civilizations with radically different ideas about what life, nature, and progress should mean.

On Veyruun, countless peoples exist within an ancient living world whose ecosystems predate any civilization that inhabits them. Primal's cultures are inseparable from that environment, while the Hadria Combine approaches it as a source of biological resources, territory, and opportunity.

The resulting conflict has made Jendarri increasingly significant as the boundaries between Realms begin to weaken. What was once an isolated corner of the Omnium is becoming a point of contact between worlds that were never meant to meet.

The Empyrean Plane

The Empyrean Plane is a physical realm without a fixed location. It exists beyond ordinary concepts of geography, occupying a place in reality that cannot be reached.

It is the center of Eclipse and the home of the Ilyri, beings whose nature allows them to cross the Veil and enter other Realms without relying on Rifts created by the Convergence.

Empyrean Plane itself is diffuclt to understand. Its landscapes, structures, and boundaries do not conform easily to the physical laws of other Realms, and yet it is home to numerous physical beings.

To most, the Empyrean is less a distant world than an intrusion from somewhere that should have remained unreachable.

Kovanthe

Kovanthe contains the Rel Galaxy, an immense region of inhabited space claimed in large part by the forces of Dominion.

They have has conquered hundreds of worlds throughout the galaxy, establishing its primary operational center within the Morgath planetary system. At its epicenter: Morgath Prima.

Kovanthe is defined not by a single world, but by the scale of the civilization that has expanded across it. Its vast distances conceal countless occupied worlds, contested territories, and civilizations absorbed into Dominion's reach.

Yet their control is not absolute. Resistance continues to emerge among the worlds it has conquered, including the growing efforts of AEGIS to reclaim them.

The Abyss

The Abyss is a finite Realm that cannot be understood through ordinary topology. Its boundaries exist, but cannot be reached in any conventional sense. Those who travel outward eventually find themselves returned to somewhere within the Realm, making its limited space effectively endless.

Much of the Abyss consists of immense subterranean caverns, though an impossible sky illuminated by twin moons stretches above. Beyond this enclosed system lies nothing that its inhabitants have been able to reach.

The Realm is home to Nethrys, though little is understood about the civilization that has grown within it. Though the Abyss itself cannot be escaped through conventional means, legions of Nethrys have nevertheless appeared beyond its boundaries. The Abyss is not entirely isolated from the rest of existence. Throughout history, portions of it have intruded upon other Realms, most notably Quill. The inhabitants of the Daylands remember these incursions as manifestations of "the Dusk Below", giving rise to countless myths of demons, spirits, and things crawling upward from beneath the world.

With the Veil now broken, the boundaries between Realms have become increasingly unstable, and Nethrys has begun to exploit the fractures. Whether their incursions are deliberate acts of conquest or merely aberrations of the Abyss itself remains unknown.

Something from a world with no way out has nevertheless found ways in. And beneath it all, something ancient is beginning to wake.

Ythram

Ythram is the Realm containing Eionaris, the homeworld of the hivemind Nexahl V'oth and the origin of the Xeno.

Little is presently known of the wider Realm beyond Eionaris. Encounters beyond Ythram make it difficult to determine which species are native to the Realm and what is a foreign entity that has become an extension of the hivemind. At least several hundred vastly different species have been contacted among the Xeno, ranging from biological organisms to artificial and biomechanical lifeforms.

As contact between Realms increases, Ythram has become one of the least understood realities known to those beginning to study the Omnium. Even the nature of Eionaris itself remains uncertain beneath the influence of its most powerful inhabitant.

Quill

Quill is a Realm containing the Daylands, the corporeal world inhabited by the Ancient and the kingdoms of Aetherion, Haskul, Asendria, and Far Reach. To those living here, existence is traditionally understood as a world suspended between two greater realms. The Daylands lies between the Dawn Above and the Dusk Below.

These beliefs are not entirely mythical. Both the Empyrean Plane and the Abyss have intruded upon Quill throughout its history, leaving behind stories that have shaped its cultures and religions.

Yet the inhabitants of the Daylands do not understand these Realms as the Omnium does. They are not literally the heavens above and hell below, but separate realities whose influence has crossed into Quill. For the Ancient, however, the distinction is meaningless as it remains caught in the middle. The unveiling of the Nexus is forcing them to learn what those legends were really about.

Vaij

A Realm with little intelligent life. Trillions of planets are home to cities that were once bustling, but now are empty and neglected for a millennia. Scavengers has found their way into the Realm and have been looking valuables among the remains.
