Isekai has started its grand restructuring! Please bear with us as things move around and get situated in their new home.
Names are also in the process of changing, so some names are inconsistent currently.

An Introduction to Isekai

A Fantasy World of Chaos and Triumph

No one is exempt from the movement of time in Isekai. Not the Dragons and their hoards nor the near-immortal Ancient Fey that live throughout the world. Even the gods are subject to the swift movement of the millennia, pushed ever forward into the abyss of time by the world and her whims.

Adventure Forth

Another sun rises, but where do you find yourself on this day? Do you look out upon the scarred earth, blistered and scorched by events that happened centuries ago, or do you forage amongst the lush greens of one of the world's many forests, only seeing the effects of the past in the deep ruts left in the trees that have lived for millennia? Somewhere nearby, tucked amongst the foliage of the land, a shrine that speaks "truth" will tell the stories that the land fully cannot. The landscapes and the runes and ruins of these shrines tell of the cataclysm, the war that brought unspeakable horrors to the lands of Isekai.   The history hidden in these shrines is just a small part of the world, one steeped in millennia of gods and those that wish to become gods, of those immortal and those whose lives are nothing more than a passing second in the history of the world. Murals and runes sealed in ruined temples speak little of the gods and their silence, the persecution that ran rampant, or the deals the fledgling Elder Races made with deities in order to survive in a world easily ran by those that live near infinite lives. The histories enshrined about the Eldritch War tell little of the world beneath the world, or the other planes that the denizens of Isekai call home. It is nearly impossible to keep such a history, but Isekai is a living history, her story written in every being and every landscape. She keeps few secrets, the key is to find them.   Wherever you may be, you have entered Isekai, a world of deep history and deeper mysteries. May you find favor with the gods or those that walk the earth and call themselves gods. May you survive the trials the world has for you, and may you never find yourself on the wrong side of the world, for she is fickle and cares for no one.  

Welcome to Isekai

Isekai is a high fantasy setting created by RiverFang and Shiftrex to be used for our custom TTRPG (currently named Storybook) and a place to hold the fantastical stories that we dream up. Magic and fantasy abound, weaving a world of power, secrets, and beings that seek both.   This world seeks to create an interesting setting that has a deep and rich history that was nearly erased during the events of the Eldritch War but has learned to flourish in a world greatly changed. Scars from the century-long war mar the landscape and Isekai's people, some being lost to history while others appeared seemingly out of the rubble of the great war.   The Divine Races and Elder Races are only a few of the races that roam the northern continent of Vóreios and the southern continent of Nótios, creating a mix of conflict and camaraderie that extended far beyond the battles of the Eldritch War.   Isekai offers many adventures, from the normalcy of the surface to the dark depths of Káto to the wonderland and twisted planes of the Wandering Forest and the Lost Paths, one could adventure a millennia and never find the end of Isekai. Even the gods do not know the full secrets of the world.   No matter where or how you enter this world known as Isekai, you will find yourself on the edge of adventure, a single choice leading you forth into the mysteries and histories that were deeply changed by a war that occurred really only moments ago in the scheme of the world's entire history. For those that live nearly immortal lives, does three hundred years really matter that much?

First, there were the gods, deities that called Isekai their own, ready to shape the fledgling world through their own creations. Like the mortals they would soon create, even the gods could not agree upon things. They split themselves into pantheons, hoping to find others whose likemindedness would allow for decisions to be made and for Isekai to be shaped to the gods' whims. The Eight Houses of Isekai were raised, each one led by a deity strong in the ideals which the house was meant to hold. War, Trickery, Order, Nature, Life, Knowledge, Death, and Arcane would become the pantheons the gods aligned themselves into, with Kallex, Niteara, Varell, Lycana, Ygg, Cique, Drasil, and Olik arising as the pinnacles of these pantheons.   Soon the deities would begin shaping the world, creating their mortal children to roam the earth. First came the four races of the Divine Races, races to hold the wealth of knowledge available in Isekai. Then came the races of the Elder Races, those of much shorter lives that would enjoy the world and revere the knowledge gathered by the older races.

The World

Two large continents define the world of Isekai, Vóreios in the north and Nótios in the south. Both are distinct, from their climate to their peoples, these two continents could not be more different. Even so, both were ravaged by the Eldritch War, leaving deep scars in the earth and the people that call this world home.    

History & Lore

The races, cultures, and languages of Isekai define so much of what the world is outside of the realm of the gods. Dozens of peoples and their languages roam across the lands, defining borders and crossing them with the breadth of their histories. The lore of the world is entrenched in these people and how they rose from the ashes as the Eldritch Horrors left the earth. The Eldritch War brought its own intricacies to the lore of the world, things that defy explanation.    

Lore & More

Fantastical stories came from the Eldritch War. Some were of blood and gore, victories won on the battlefield against creatures that should not exist in the world, stories of loss and destruction. But others still were of good, of fantastical heroes that appeared from nothing, seemingly steeped in magic and the heart of the world.   Isekai had deeply changed from the war, buried in the blood of her people, her children lost to the horrors that came from someplace else. Where new stories spawned, others were lost as the peoples that once lived in the Deadzones were erased, only to be replaced by hopeless swaths of sand. Most would recover from their battles, but few would never return to Isekai, changing the world's path, for better or worse is still unseen.   These new stories started here, simply with the Black Children and their incredible powers. After three hundred years, this is still but a myth, but so many hope for its truth, for the possibilities of heroes of great power that came out of such a bleak time. The people of Isekai hold onto this story with hope, a hope that brought light in the deepest darkness.

Behind the World of Isekai

The Game

A few years ago, we had a grand idea to play a game of D&D5e that utilized many of the rules that we believed were often left out of the game as it makes the game much more difficult. With these changes in mind, the campaign known as "hard mode" was born, with Isekai at its core. Since that more "difficult" beginning, we've played countless campaigns, written stories, and worldbuilt far more than we had ever expected.   Our World Meta covers a large portion of the goals and direction that encompass our quest to build not only our games but our world. So much more is occurring as we work to make Isekai more self-sufficient and an endeavor that will stand the test of time and real life.   As of August 2021, we have begun our foray into building our own TTRPG system, one that we are calling Storybook. The world of Isekai is meant to be an adventure, one full of stories told by the world and those that live in it. The goal of the system is to build something that allows players to tell their own stories in our world and delve into the lore as deeply as they can.   This system will take time to build, but we hope to eventually release it to the Anvilite community that has allowed us to grow far beyond what we had ever thought possible in our writing, storytelling, and playing.  

Special Thanks

After all this time on World Anvil, the list of people to thank is too great to mention here. Without this community, Isekai would not be what it is, the layout would not look like it does, nor would our writing be improving as we strive to reach the heights that are demonstrated in the community.   We would especially like to thank Janet and Dimitris and the entire World Anvil team for the work they put in making this platform what it is. Without them, Isekai would not exist in its exponentially growing size. It would be nothing more than some scattered notes lost in a document somewhere when it is so much more now.
