The Physical Planes of the Cosmos form a vibrant and multifaceted foundation of existence, each realm embodying essential elemental and divine forces. From the Mineral Plane's solid landscapes and the endless ocean of the Tidal Realm to the Zephyr Realm's boundless skies and the Nexus's gravitational intricacies, these planes interlock to create a dynamic universe. The Shattered Domain adds a layer of celestial complexity, housing divine beings and their followers across fragmented territories. Together, they present a universe ripe for exploration, adventure, and the unfolding of cosmic mysteries, offering boundless opportunities for those brave enough to navigate their diverse and elemental wonders.

The Prime plane is the foundational realm of balance, where the Arcana and The Dim converge. It is the original source from which both sprung, rich with magic and inhabited by faeries, fey, and various magical beings. A realm of diversity and equilibrium, it stands as the heart of the cosmos.

Arcana is a vibrant and magical mirror of the Prime plane. Overflowing with arcane energy, this realm is a haven for the most whimsical and powerful magical creatures, where the landscape itself pulses with enchantment.

The Dim, referred to as the shadow or upside down, presents a bleak and dismal mirror to the Prime plane. Stripped of magical power and unpopulated, it is a realm of emptiness and shadows, where light and life seem to have been withdrawn.

The Shattered Domain, or the Plane of Ix, serves as the divine abode of the gods, formed from the remnants of the original god Ix. It is a realm where celestial shards have given rise to divine beings, each ruling their portion of this fragmented yet sacred plane.

The Mineral Plane, representing the earth element, is a realm of unending landscapes of crystalline formations, metal mountains, and gemstone forests. It's the backbone of the physical world, providing the raw materials that shape the cosmos.

The Tidal Realm, embodying the water element, is an infinite expanse of seas and oceans. Home to majestic underwater cities and mysterious aquatic creatures, it is a plane of change, depth, and life.

The Zephyr, the plane of Air, is an endless sky filled with floating islands and boundless horizons. Governed by the winds and home to creatures of the air, it is a realm of freedom, movement, and inspiration.

The Ember, representing the fire element, is a domain of perpetual combustion and renewal. With landscapes dominated by volcanic activity and rivers of lava, it is the crucible of creation and destruction.

The Nexus, the plane of Gravity, underpins the physical laws of the cosmos. A realm where gravitational forces shape the very fabric of existence, it offers unique challenges and opportunities for those who traverse its variable landscapes.

The Mystical Planes encompass nine interconnected dimensions beyond tangible reality, each embodying a distinct aspect of the universe's metaphysical fabric. From the soul-transit of The Silver Road to the raw life-force of The Source, from the frozen moments of The Continuum to the dream-built terrain of The Somnium, these planes underpin the forces that the physical and soul realms cannot account for on their own. They are not destinations so much as conditions — states of existence that shape everything else.

The Silver Road is the great transit of the cosmos, linking the physical realms to the Soul Planes. A vast, star-filled expanse where the spiritual and material converge, it carries souls, energies, and travelers across existence. It is neither fully physical nor fully spiritual, but the seam between the two — and it responds to those who cross it accordingly.

The Veil wraps around the physical planes like a second skin, a realm of mist and shifting half-light. It facilitates movement and magical interactions across the cosmos, and its ghostly corridors are home to things that exist between states — not quite here, not quite gone. The plane embodies transition itself, and nothing within it stays fixed for long.

The Drain is the force of entropy given form — a realm of absolute darkness where life's energy is negated and existence thins to nothing. It is the essential counterbalance to The Source, underpinning decay, death, and the return of matter to nothing. Nothing thrives here. Nothing is meant to.

The Source is the cosmic wellspring of life: a boundless domain of pure, radiant energy from which all living things draw their essence. Blinding in its intensity, it is the counterpart to The Drain — and just as dangerous to the unprepared. Too much of The Source is as lethal as too little; it does not nurture so much as overflow.

The Somnium is where the sleeping minds of all sentient beings converge, their dreams given form and terrain. Governed by the Lord of Dream, the landscape shifts with the weight of collective imagination — beautiful, monstrous, and impossible in equal measure. What happens here has consequences in the waking world. Those who dismiss it as unreal do not understand it.

The Crucible manifests the emotional spectrum of all beings as physical terrain. Joy, grief, rage, longing — they are not metaphors here, they are landscape. The plane fluctuates constantly, and travelers find their own emotions amplified and externalized the moment they arrive. It is not a comfortable place to visit, but it is a revealing one.

The Weft is the spiritual substrate of the natural world — the dimension where the spirits of animals, virtues, elements, and living things reside and from which they influence their material counterparts. It mirrors the natural world as it exists without civilization: wild, ordered by instinct and cycle, and largely indifferent to mortal concerns. The spirits here are not gods, but they are not minor either.

The Continuum is a realm where past, present, and future exist simultaneously and without hierarchy. A traveler here does not move through time so much as they move through the record of all moments at once. Governed by the Time Lords and their enigmatic master, it is one of the most restricted planes in the cosmos — not because it is difficult to enter, but because the consequences of careless travel here ripple in every direction.

The Void is the outermost boundary of the cosmos — the place where reality ends and something else begins. It is not empty in the way a room is empty. The Void is the absence of the conditions that make existence possible, and the things that have adapted to live there are shaped by that absence. The Ancients retreated here long ago. Whether that was exile or sanctuary depends on who is telling the story.

Welcome to the Soul Planes

The Soul Planes exist outside the spatial arrangement of the physical cosmos — organized around death and its consequences rather than matter and force. Every soul passes through Sheol at the end of life, where it is assessed and directed to wherever the weight of its existence places it. The nine planes cover not just moral judgment but the full range of existential conditions.

A structure of nine levels, each organized around a specific category of harm. Souls arrive at the level that corresponds to the nature of their worst sustained choices.

Nine layers of genuine reward, ascending from order and valor to wisdom, love, contentment, and creative freedom. The Aelar who govern it are complex beings with their own concerns. Souls here are considered whole in a way that souls elsewhere are not.

The place of assessment — not a destination but a passage every soul makes. The process is experienced as a journey through one's own life with full clarity about what was done and what it cost.

A plane of unblemished chaos that preceded order rather than simply defying it. Souls here are those whose lives resisted any organizing principle entirely.

The counterpart to Limbo — a plane of total order, purposeful and relentless. Souls here are those who existed for structure as an end in itself rather than a means.

A plane of unceasing war, where every interaction is a contest and peace is structurally absent. Souls here are those who required conflict as a condition of existence.

The counterpart to Bellum — a plane of unceasing peace where conflict is structurally absent. Souls here prioritized peace above growth, change, or productive friction. The plane is exactly as tranquil as it appears, and exactly as static.

Perpetual motion. Nothing stops, slows, or rests. Souls here could never be still; travelers find their own restlessness amplified the moment they arrive.

Total stillness. Time passes and leaves no mark. Souls here are the forgotten, the unmoved, the permanently unreachable — those who matched no other plane's shape.
