The oldest and most developed part of the universe, the most well known planets and other important locations in the Core, and their political affiliations are: 

Freeport:

- Voidside: The poor half of Freeport, a mass of housing and shacks stacked up to 3 floors high. Home to most of the pirate crews that aren't part of the Unknown.
- Brightside: The wealthy half, far less densely populated and instead filled with a luxurious assortment of casino's, hotels and other businesses promising to sate even the most degenerate vices. Home to the Big Five crews of the Unknown, their associates and a constant flow of merchants and rich tourists.

Ego Ultd. and Elements Unbound:

- Twilight World: Homeworld of The Travelers and many races like Humans, Orcs, Dwarves and Halflings. These days its galactic presence is mostly focused on the two megacorporations vying for dominance over New Amet, the largest metropolis in the Core. 

- Broken World: Two broken halves of a world on opposite sides of the Core with between them a large portal big enough for Spelljammers to move through. The asteroids clustered around the portals are home to Plasmoids and Bainen's Delve which was founded by a Dwarven mining expedition sponsored by Elements Unbound. 

Trimino Combine:

- Water World: Homeworld of the Triton race and seat of the royal Celanovia - Krarrk family for half of each year. 

- Maze World: Homeworld of the Minotaur race and seat of the royal Celanovia - Krarrk family for the other half of each year. 

- Kraken World: Colony world of Tritons yet all know it is truly ruled by the planet's apex predators: the krakens. 

- Drowned World: For decades the Triton and Minotaur nations fought a war over this world until it served as a catalyst for their union. Now it is best known as the location of Enigma LLC's headquarters. 

The Eternal Dominion: 

- Phantom World: Ancestral homeworld of the Elves, it was all but destroyed in ages past but now it is once again home to the high elves of The Eternal Dominion. 

- Plague World: Mysterious planet, no living being has set foot near it and returned. The Eternal Dominion claims it based on their using undead minions to explore it. 

Church of The Travelers:

- Goblin World: Homeworld of Goblins which might have resigned it to obscurity if not for the fact that their worship ascended The Travelers, a new pantheon of living gods. Now their priests called The Custodians are one of the most common sights in the Core as they spread their faith throughout the universe. 

Giff:

- Powder World: Homeworld of the Giff who are one the youngest races only gaining consciousness after Itoa's rebirth after The Reckoning. The Giff are known for their obsession with gunpowder which led to them inventing firearms, instantly making them an important player on the intergalactic stage. 

Dragons

- Hoard Worlds: the lair worlds of the Core's most ancient primordial dragons, some of which are worshipped as gods like Pythios and Agoras. Each color of dragon has their own world with its own hierarchy, or lack of it, depending on the dragons' personalities. Since the Age of Connection Dragonborn mercenaries have spread throughout the core working to gather treasure or otherwise fulfill the will of their dragon progenitors. 

Gnomes

- Gnomeheim: The location of the Gnomish homeworld is unknown even to the Gnomes themselves. Only true gnomes can cast the spell allowing them to return. It is said to be home to both spectacular natural beauty cultivated by the Forest Gnomes and the legendary workshops of the Rock Gnome tinkers who created the Warforged and have traveled throughout the Core on their carts since long before Spelljammers were invented to sell their goods and services. 
 

The Swarm

- Swarm Worlds: an invasive species of insects which has been spreading from world to world even without the use of Spelljammers. 

The Travelers: A pantheon of living gods who ascended during The Reckoning when they defeated Areth and saved the Core for his tyranny. Their priests are called The Custodians, after the Goblin librarians of The Vault who first began worshipping The Travelers as gods, The Vault still being their largest temple. The Traveler's followers mostly worship all Travelers but most will have a favorite they pay extra attention to.

• Maevin, the mistress of frost and arcane knowledge. Her custodians are often wizards or clerics of the War or Knowledge domains who have chosen their own evil to destroy.
  
• Red, the keen, lord of the edge. Red's custodians are often lawyers, notaries and assassins, who seek to learn more about contracts and punish those who fail to uphold them. 
  
• Alvaro, the mysterious lord of shadows. Alvaro's custodians are as mysterious as their god and so are rarely seen. They fight alongside their lord in his unseen shadow war with the necromancers and abominations of Ilalokthramek over the very soul of the Void, seeking to create order where there was once only chaos.
• Sessa, mistress of transformation, and CEO of Elements Unbound. Most of Sessa's custodians serve as managers and officers within her corporation although many also serve her in their own way throughout the core, their method of worship as changeable as their goddess. Sessa is also believed by some to have created a sentient race called the Plasmoids, many of whom worship her as their creator.
  
• Myra, the kind, lady of wishes. Her custodians are often Bards, Druids and Clerics who strive to help and assist the unfortunate and worthy.
• Diesa, protector of the dead, the twice dead. Her custodians are often Paladins and Clerics of the Grave domain, they travel throughout the core to cleanse necromancy and guide lost souls back onto the path.
  
  

The cosmic explosion: most Giff don't worship a specific god, instead they endeavor to recreate the explosion which breathed sentience into their species by any magical or non-magical method possibe, the most common being gunpowder. Since their emergence onto the interplanety scene they have learned this explosion was in fact the rebirth of Itoa after The Reckoning. As such some Giff might also worship The Travelers as prophets of the explosion.

The neverending currents: The closest thing to a god Tritons worship is their queen, however they also believe in a more ethereal concept of the neverending currents which guide and shape their life path. Someone who has found their purpose and dedicates their life to it might be said to swim with the currents, while someone who is rebellious and refuses to take their proper place in society can be said to swim against the currents.


Ilalokthramek: Previously categorized as one of the old gods, however during Nightfall it was revealed Malgali Forlonde was his apprentice and he took control over the High Elves leading them onto a dark path of necromancy and void magic. Malgali and his followers have since founded The Eternal Dominion.

The Cabal: The daughters of Ilalokthramek who have led their father's followers since their father's ascension and their subsequent exile into the deep tunnels of the underdark below Hadira. They now resent their father for abandoning them. With the recent return of their mother Ithren they have led the Drow into out of the underdark and into the void aboard giant arkships.

• Icharyd the Mistress of the web: fate, spiders.
• Saradreza the Mistress of blood: vampires, undeath.

The Masked Host: A pantheon of gods worshiped by the Wood Elves of Hadira and New Amet.

• Ethor, God of Nature and Fire - Cycle of life, creation and destruction, order and chaos. From the ashes of death grow trees of life.
• Ithren, Goddess of Creativity and Death - Innovation and stagnation, life and death. Immortality is found not in life but after. She was the wife of Ilalokthramek and there are rumours that her avatar is now also worshiped by the Drow.
  
• Finde, Goddess of Wisdom and Perfection - Wisdom is knowing there is no perfection yet still to reach for it.
• Ellartas, Goddess of the Arcane and Battle - Preparation and action, decisiveness and deliberation, force and subtlety. Take care even when you need to act now but do not dawdle even when you have time. 
• Celadir, God of Travel and Music - Future and past, away and home. Without discovering new things, you can’t appreciate what you already have.

Pythios and Agoras: The twin dragons of Fire and Ice worshiped by the Orcs of Gashuk on Twilight World. They believe Pythios and Agoras created life on their world by repeatedly freezing and boiling the world during their eternal fight. Like the primordial dragons they worship their followers are in an eternal mortal struggle. 

The old gods: a collection of gods from Twilight World whose worshipers were all but exterminated by the Arethian Empire. Their worship was outlawed and only held alive in the furthest fringes of the empire like Hadira, since The Reckoning worship of all but Kiral and Ilalokthramek has become all but extinct. 

• Kiral, the defender: Abjuration, commonly depicted as a stout warrior wielding a large shield. Most notable for its Paladin order The Circle of Kiral who now police New Amet.

• Maelik, the elder: Transmutation, commonly depicted as a golden tree bearing fruit.  

The Three: The Three are the mythical fey gods of Kususha Pagoda where most of the Xi'lanian survivors sheltered from Nightfall. They remain a popular religion in New Amet and among the few hardy human survivors on Xi'lan.

• Yaokami: Spirit of Change, monstrous half wolf/half fox. They personify change, trickery and predation.
• Oya-Fu’ju: Mother Winter, fully naked ancient crone with a new transparant skin, curling claws and goats legs. She personifies the cold, death and greed.
