DC Cosmology/Notable Worlds & Realms

The Mulitverse that makes up the DC cosmic landscape is composed of various vibrational realms that typicially exist either parallel or within each other, resonating at different frequencies.

Earth 0
The Earth 0 (also called Prime Earth; previously called New Earth and Earth One) is the designation given to the primary universe on which most of the adventures of DC Comics takes place. as the primary earth of the Multiverse, the effects on this universe ripples out and effects all of DC's reality.

The Monitor Sphere
Beyond the Orrery of Worlds and the Sphere of the Gods, at the furthest reachs of reality, is The Monitor Space. This realm was once home to the Monitor race. With the destruction of The Source Wall, the Monitor Sphere is the last border of the Multiverse before entering the greater Omniverse, and the massive cosmic consciousness known as the Overvoid.

Nil
the origin point and former home of the Monitors. This cosmic space was abandoned in the wake of Final Crisis and the extinction of the Monitor race.



Limbo
Limbo is the place where matter and memory break down and where the lost and forgotten go. This realms is a dimension found between the Sphere of the Gods and the Moniter Sphere. This is where heroes and characters exist even they are forgotten. Every character that exists in this space has forgotten most of their lives. The Infinite Book, the only book in the Library of Limbo, exists within this dimension and contains all of the history of the Multiverse. The Infinite Book is the one story that tells all other stories, but it is unreadable. If this book is ever destroyed, all of the Multiverse will be destroyed with it.



The Sphere of the Gods
The Sphere of the Gods is a metaphysical sphere of reality that exists at a higher plane of existence than the universes within the Orrery of Worlds, but lower than those that exist in the the Monitor Sphere. Except for a few exceptions, all beings of the Sphere of the Gods are "Multiversal Singularities", meaning that there is one version of them in the entire multiverse that exists within all realities simultaneously. 8th Metal comes from this realm and is heavily used by the denizens this sphere of existence.

Early Existence

At the dawn of creation, the energy that we know as "magic" existed in its most raw form within the plane of existence that surrounded the virgin Multiverse. From that energy Hecate, the first magical being, shaped herself out of the cosmos and became the first inhabitant of what would become the Sphere of the Gods. The Sphere of the Gods would become home to most, if not all, Gods that exist within the Multiverse, each residing in 1 of the 8 realms that make up the Sphere of the Gods. As the source of all magic, all the beings who originate from this sphere of reality wield great power and are considered gods by the beings who exist on the lower plains of existence. The Sphere of the Gods is the wellspring from which all magic flows into the Multiverse and it's power grants the gods, and those who possess godlike abilities, their power.

Realms

The Sphere of the Gods is composed of 8 realms that each act as a polar opposite to another realm within the Sphere of the Gods, such as the shining New Genesis which acts as the polar opposite to the fiery Apokolips. Each of the realm within the Sphere of the Gods is directly connected to at least 1 reality within the Orrery of Worlds, which greatly affects the natures and developments of the universes they are directly connected to, as well as those in close relative proximity to them:

Dream
Dream (also known as The Dreaming) contains all which is not, was not, and shall never be. Basically, every dream is reality in the Dreaming, and as such, the Dreaming is infinite.

The Dream is the domain of Morpheus the Dream-King and is where the courts of Faerie and Gemworld exist. it is also home to the likes of Oberon, Titania, Amethyst the Princess of Gemworld, Santa Claus, the Easter Bunny, as well as the Halls of the Endless.

Heaven
Home to the Spectre and the Host of Pax Dei, among others.

New Genesis
The homeworld of the New Gods and the Forever People. Highfather, Orion, Lightray, Metron, Scott Free all originate from here.

Skyland
The homeworld of the Old Gods. Home to the Asgardian Gods, the Olympian Gods, the Loa, the Elohim and many others who were worshipped in ancient times.

Underworld
The opposite of the Skyland. Home to the netherworlds of ancient cultures such as Hades or Annwn. Also known as the Phantom Zone, it was used by the Kryptonians as a prison for their criminals (General Zod, Xadum the Phantom King).

Apokolips
The homeworld of Darkseid and his servants: DeSaad, Granny Goodness, Kalibak, etc.

Hell
Home to Etrigan the Demon, djinn ("genies"), fallen angels, demons and the Haters of Humanity.

Nightmare
The shadow side of Dream where the Goblin Market exists. Home to the Bogeyman, haunt of witches and bad dreams.

Travel between the Sphere of the Gods and the other planes of existence in the Multiverse is normally not possible, but natural portals to the Sphere of the Gods are known to exist, with many known to be found throughout the Orrery of the Worlds.

The Speed Force Wall
the Speed Force Wall is also known as the Speed of Light and is the limit to matter. The Speed Force Wall permeates the entire DC universe and acts as the border that contains all the universe within the Orrery of Worlds. Within the Speed Force Wall are a small handful of worlds, at least half of which are currently unknown.

Wonderworld
The Former homeworld of the archetypal godlike superhero team known as the Theocracy, who sought to defend reality. Now it is an abandoned cosmic graveyard, following the attack of the Old God war machine Mageddon.

The Frequencies of Kwyzz
The Kwyzz is the radio universe embedded in the Speed Force Wall, formed as one of the Monitor Bleed Siphons. This universe punches through Skyland, in the Sphere of Gods, to enter the Orrery and is home to the champion of Kwyzz, Krakkl.

The Orrery of Worlds:
the realm where the 52 universes exist in the same space, vibrating at different frequencies, within the Bleed. In the center of it are the Rock of Eternity and the House of Heroes.

Rock of Eternity
Some time around 5,000 years ago, a great Champion created the Rock of Eternity from two large rock formations—one from Heaven and one from Hell—to hold the "Three Faces of Evil", a dragon-like demon, captive.

The Rock of Eternity would become a way station of power, a nexus of existence that channels power to the Champion who utilizes the magic of the wizard Shazam.

House of Heroes
The House of Heroes is a pandimensional satellite outside normal time and space orbiting the Bleedspace between universes. Originally used by the Monitors, it became deserted when they were all extinguished, leaving only one of them to guard the Multiverse.

After the Justice League defeated Barbatos and raised the Earth back from the Dark Multiverse, the heroes from various universes of the Multiverse started reconstructing for future generations of heroes from new universes.

The Dark Multiverse
The Dark Multiverse is a shadow under the primary Multiverse. It's a Multiverse formed from every fear and bad decision ever made or dreamt of in the primary Multiverse. Worlds in the Dark Multiverse are inherently fragile, born in a constant state of deterioration and inevitably doomed by their malformed construction.

At the dawn of creation the realm now known as the Dark Multiverse was the World Forge. The realm was the domain of a cosmic being known as the World Forger, the brother to The Monitor and the Anti-Monitor. The World Forge was rich in Dark Matter, a substance ripe with potential, which the Forger would use to forge new universes out of the hopes and fears of all sentient life, as well as the pure metals of creation. Worlds that proved themselves stable would rise up into the light to join the Orrery of Worlds, while worlds that were lacking, flawed, or corrupt at their core were destroyed so that their energies would be released to fuel the creation of new potential universes. This destruction was the task of the Great Dragon - Barbatos. However, after eons serving the Forger, Barbatos’ ambitions and lust for destruction grew until he eventually killed his master. Without the World Forger, the cycle was broken and failed universes were allowed to exist beyond their time; festering and rotting into a perverse Multiverse where all the sentient beings within suffer nightmarish ends.

Earths
Because of its nature as the cradle of yet unborn worlds, the number of worlds in the Dark Multiverse is far greater than in the normal Multiverse. Barbatos was able to handpick for Batman the "galaxies" of worlds born from just his fears. All heroes have had an impact on the Dark Multiverse, with innumeral twisted versions of heroes such as The Flash, Aquaman, and Wonder Woman emerging from the Earths in the Dark Multiverse. The designation for the worlds in the Dark Multiverse are all preceded by a minus sign; Earth -52 as opposed to Earth 52, for instance. Many of these worlds are inverse versions of worlds we've seen in the positive Multiverse. Notable inverse worlds so far:


 * Earth -44 while also similar to Prime Earth at first, features Batman becoming a cybernetic being, while Earth 44 is centered around purely robotic versions of superheroes.
 * Earth -32 and Earth 32 both deal with Bruce Wayne being granted a Green Lantern ring.
 * Earth -22 and Earth 22 are both worlds in which the Joker is killed and his death served as a catalyst for a major catastrophe.
 * Earth -12 and Earth 12 are both worlds in which Bruce Wayne and Diana of Themyscira are romantically involved.
 * Earth -11 and Earth 11 are both worlds wherein characters are the opposite sex of their mainstream equivalents.
 * Earth -1 and Earth 1 both deal with a darker, grittier take on the DC Universe, with Superman and Batman serving as the initial focus.

Trivia

 * The Batman Who Laughs mentions that somewhere in the Dark Multiverse, there is a version of Bruce Wayne who fused with Lex Luthor and almost chose him over the Murder Machine.
 * Each universe is based on any hero or villain's unspoken fears.
 * According to Darkfather, most of Superman's Dark Multiverse versions are tyrants who rule humanity.
 * According to the Robin King, evil counterparts of villains take the form of good version of themselves as they fear being good.
