Estoria

The World Overall
Estoria is the name given to the primary planet residing within the Prime Material plane. It includes the continents of Zeladin, Grimmjotun, Gredd, Feyrock, Claucus, Chiselbreak, and the lesser landmasses of the Absen Land, the Serpent's Clutch, and the Estoran Dominion. The landmasses are surrounded by six named seas; the Grand Victran, the Minor Victran, the Emerald Ocean, the Cold Water, the Endless Western Ocean (aka the Great Maw Sea), and the Grimmwater.

The Elemental Chaos and Creation
Four elementals of titanic strength residing within each of the four elemental planes managed to break free from their planes, bursting forth into the voidspace of the Blind Eternities. These four titans clashed and began an era of Elemental Chaos lasting 35,000 years. They continued to amass power over this time, conflicting with each other until, tiring of the constant warfare, they struck an accord and decided to occupy this section of the Blind Eternities together. The four of them began to work together to craft land and sea masses ultimately resulting in the planet and, ultimately, the entirety of the plane of the Prime Material. Eventually, wishing to enjoy their creation, they struck another accord: each of them fractioned themselves, allowing a section of themselves to split off into the Blind Eternities so that a shape of themselves would remain on the prime material without destroying it. They took names; Porphyr, titan of fire; Etisan, titan of wind; Golt, titan of earth; Dilandia, titan of waters.

They began to populate this new plane with creatures and beings from their home planes. During this time, they each took a favorite creature. Porphyr favored the pheonix, which ignited his forge. Dilandia favored the kraken, a powerful creature that lorded over the deep. Golt favored the hydra, a symbol of power and the ability to regrow. And Etisan favored the pegasus, a beast of the earth given to the sky and able to soar.

While the four of them shaped their new home, the sections of themselves cast into the Blind Eternities were brought together and stitched together by the last remnants of a race of starlight elementals. This amalgamation of elemental power would be shaped and become the titan god of the arcane, Celestadon, the original source of raw arcane energy as well as divine within the prime material plane. Celestadon approached the four titans and offered to grant each of them craft sentient beings native to this new plane. Each would craft two creatures, and two of each creature.

With Porphyr, he crafted the giants, carved of the mountains of the fire planes, and the dwarves, crafted to help them forge.

With Dilandia, he crafted merfolk, who shared her love and affinity for the ocean, and gnomes, who shared her clever and inventive mind.

With Golt, he crafted elves, carving them from the woods of the Feywild itself, and halflings, who appreciated a good days work with a good days rest.

With Etisan, he crafted the aarakocra, an attempt to craft something in the image of himself, and the dragons, a result of his jealousy of the might and strength of the giants. He crafted the latter through deception; going to each of the other titans, he claimed he was too weak to craft a creature with his own might, he requested a piece of each of their strengths. They each allowed this, and the dragons were born. After their conception, and their subsequent callous natures were revealed, the guilt manifested into what would later become the god of lightning and deception, Zetseg.

Celestadon himself crafted only one race, though he created four of them. He created humans. They were named Leonia, Aurelia, Yenn, and Draymon.

The titans remained to oversea the development of these new beings, and ensured their propagation. While many of the beings crafted by the titans had long to immortal lifespans, humans were given a caveat with their immortality. Should one of them die, their immortality would be lost. The titans remained amongst their creations, amassing power now through worship rather than purely elemental temperament. Seeing this a their final stage, the titans shed the physical bodies they had attained to walk the Prime Material, leaving the corpses as vestiges upon the plane of Estoria itself.

Porphyr's body turned to stone and became a massive volcano on the continent of Zeladin. It is said Dilandia's body dissipated into the waters of the Emerald Ocean, and though none can confirm it, it is believed to float as a single crystal blue pool somewhere deep within the ocean. Golt's body remains on Feyrock as a testament to nature's power; an indomitable and massive tree at the center of the island, it's roots growing directly though the stone. Etisan's body was cast into the sky, and took the form of a large, thick storm cloud that would forever circle the plane. Around this time, the aarakocra departed from the earth of the plane, taking up residence on the body of Etisan, and removed themselves from the history books in doing so.

As the four titans ascended, they gained divinity, drawing the attention of a distant and powerful being residing within the Blind Eternities that would come to be known as the Divine Gate. A strange eldritch being that walked a fine line between aberrant and divine power, it saw the problems that could be caused should such divine creatures return to the plane. So it created a barrier of sorts, preventing the divine from passing through it. Other beings that had begun to collect worship and divinity were also contacted by the Divine Gate and ejected beyond it, including the now divine Zetseg. Second among these was Potess, the goddess of beasts and portals.

This began what was known as the Secular Era, also known as the Era of Exploration.
