Beyond the Ethereal lie innumerable planes - some vast and eternal, others as fleeting as a half-remembered dream. The Multirealms is not an ordered system of numbered planes arranged by alignment or element. It is an ecosystem of realities, each defined by its dominant resonance.
Every deity that has ever been worshipped - in any mythology, any legend, any game system, any human tradition - exists somewhere in the Countless Realms. They are not metaphors. They are residents.
The Divine Realms
In the upper resonance reaches of the oblong, where belief shapes matter and a god's will and the fabric of existence are the same thing, lie the divine domains. Each god of sufficient power maintains a domain shaped entirely by their nature, portfolio, and the accumulated faith of their worshippers.
Walking into a divine domain is walking into a continuous embodiment of a deity's nature. Creatures who share that nature find it beautiful and clarifying. Creatures whose natures conflict with it find it steadily hostile - not through any intent, simply because the fabric of the place resonates against them.
The Lower Realms
The lower realms are not one hell. They are many. There are lower realms of pure entropy. There are hells of specific suffering - places whose very fabric resonates with particular kinds of pain, crystallized over enough time to become a universe. There are abysses with no organizing principle except descent. There are infernal kingdoms with hierarchy and politics.
What lower realms share is the gradient's effect at that end of the oblong. Reality is dense here in a way that resists hope. Evil resides in the lower realms not as metaphor, but as a condition of existence. Creatures that emerge from the lower realms carry that evil with them. They are shaped by a reality where the fabric itself does not naturally support recovery, growth, or hope.
The Specialty Realms
Between the divine upper reaches and the lower depths, scattered throughout the Ethereal's infinite middle space, lie the specialty realms - places defined by a single dominant quality of experience that has accumulated enough weight to become a universe.
The Realm of Dream
Dream borders every sleeping mind in every Material world simultaneously. In sleep, consciousness partially departs the body and drifts into Dream. The Realm of Dream feeds on consciousness and feeds consciousness in return. It operates on narrative logic rather than physical logic - cause and effect apply the way they apply in stories, not physics.
The Realm of Hunger
Hunger is a realm defined by the absolute absence of satiation. Entities from Hunger consume because the realm demands it. They will eat material objects, magical energy, memories, hope, and life force with equal indiscrimination.
The Realm of Song
At its most beautiful, a place where music is the governing physics and harmony is the highest law. At its corrupted edges, where the Song has turned inward, it produces things that consume sound rather than make it.
Other Realms
The Multirealms contains specialty realms for which mortals have not yet coined useful names. A realm of pure unresolved potential. A realm of accumulated regret. A realm that corresponds to the exact emotional state of a decision being made at maximum weight. A realm of echoes. A realm of things that were almost real but weren't.
