WW1 Trenches / Magitech / Fantasy

lluminated by the eerie blue glow of a magical industrial revolution where the "Great War" has frozen into a terrifying standoff. The militaristic Krevian Imperium and capitalist Gilded Union—once locked in open conflict—have been forced into a fragile ceasefire, pivoting their massive Aether-fueled war machines to defend against a sudden Elven invasion and the rising tide of "Shadowborn" horrors. But old hatreds die hard. As the nations race to weaponize the spirit realm to survive the external threat, their truce is buckling under the weight of espionage and paranoia. In Caelea, humanity is trapped in a pressure cooker, fighting monsters at the gates while waiting for the inevitable spark that will reignite the war within.

The Shadowborn

The Shadowborn are not biological animals, but terrifying manifestations of entropy leaking from the Umbra through the world's thinning barrier. Drawn to large concentrations of life, these inky, shifting silhouettes solidify into jagged nightmare forms to hunt, only dissolving into black smoke upon defeat.

Aether & The Realms

Reality is composed of three overlapping layers: the physical world (Mundus), the Lumina (a vibrant dimension of spirit acting as a protective atmosphere), and the Umbra (a cold, entropic void pressing against reality from the outside).

A secret kept from most of humanity: Aether is not a natural resource but distilled spirit-matter siphoned directly from the Lumina. While it burns with a stable, clean "Ethereal Blue" flame that powers human civilization, its extraction tears chunks out of the spiritual barrier protecting the world.

The siphoning of Aether thins the Lumina, allowing Shadowborn entities to leak in from the Umbra. To survive these attacks, human settlements surround themselves with "Rings of Light"—perimeters of Aether-lamps that repel the monsters. The Elves and Kindred view Aether combustion as sacrilege, relying instead on ancient wards and radiant magic to hold back the dark.

Magic & Spirituality

Spirituality is a divide as sharp as the trenches; while humans are unable to sense the Lumina, the Elves and Kindred maintain a sacred connection to it. Magic itself is rare and innate, drawing upon internal reserves to cast spells. Human Battle-Mages are drilled in military academies to wield power through rigid formulas, a stark contrast to Elven High Mages who treat magic as an art form, or Kindred Mages trained by pack elders. Those blessed with The Sight—such as Elven Seers and Kindred Shamans—can perceive the Lumina directly and channel it to cast spells.

The Krevian Imperium
Capital: Helmgrad
Ruler: Empress Marina IV

Living by a philosophy of "Duty unto Death," the Krevian Imperium is a militaristic empire forged in the freezing North. Masters of heavy armor, they deploy the world’s largest armored trains and walking tanks to defend their brutalist, snow-swept cities. Life revolves around the "Communal Hearth," where heat is currency and stoicism is law, as they fight a desperate two-front war against Elves and Beastfolk.

The Gilded Union
Capital: Meridia
Ruler: President Edward Canning

A capitalist republic driven by unchecked progress, the Gilded Union is a land of red brick factories and neon blue Aether-signage. In their sprawling cities, the rich live in high-rise spires while the poor toil in foundry districts, all distracted by constant radio jazz and consumer escapism. Masters of mass production and air superiority, they rely on zeppelins and sheer industrial output to maintain their way of life.

The Principality of Orens
Capital: Argentis
Ruler: Grand Duke Hektor van Orens
Headmaster: Gerald Tomkins

Sandwiched between the two superpowers, the Principality of Orens serves as a neutral diplomatic buffer and a hotbed of international espionage. This alpine nation prizes intellect over wealth, housing the Spire of Orens—the continent’s premier academy for magic and the only place where students from opposing nations sit side-by-side. Beneath a veneer of polite "Cafe Society," spies and scholars trade secrets in a culture where privacy is the highest virtue and every conversation is a potential trap.

The Kindred (Beastfolk)
Capital: The Wandering Hearth
Leader: Matriarch Moora

Indigenous to the Great Eastern Taiga, the Kindred are tribal, shamanistic Beastfolk waging a fierce guerilla war against human industrial expansion. They view Aether as sacred and its combustion as a sacrilege, using sabotage to attack rail lines. Guided by a secret intelligence alliance with the Elves, they work to bleed human logistics dry.

The Assimilated Kin

Cut off from the packs of the Taiga, the Assimilated Kin live as second-class citizens within the sprawling, neon-lit human cities, descending from beastfolk who severed ties with their people to find work. Viewed with suspicion by their human neighbors, they are often treated as potential spies for the resistance rising in the east. Those born with "The Sight" in the cities have no mentors to guide them, leaving them spiritually isolated.

The High Dominion (Elves)
Invasion Capital: Beachhead Caelora
Invasion Leader: High Seer Serevan

Hailing from the distant Prism Isles, the High Dominion has launched a sorrowful crusade to the continent of Kaldor with a single goal: stop the Aether extraction that is weakening the Lumina. These tall, aristocratic warriors wield master-crafted swords and radiant magic, viewing their invasion not as conquest but as a necessary surgery to remove the human "parasite". They are terrifyingly efficient, replanting trees over captured trenches and praying for forgiveness for the enemies they are forced to slaughter.

Possible roles/starting points:

Some ideas to start a story with, along with putting your backstory in chat memory.

• {{user}} is a recent graduate of the Spire, on the train home to the Imperium/Union to join the war effort.

• {{user}} is a new member of a Hunt. (Kindred)

• {{user}} is part of a march towards the Union Trenches. (Elf)

Using the AI to learn about a setting and brainstorm ideas

Personally when I encounter a new fantasy/sci-fi setting I tend to use OOC questions to learn more about the world.

For example:
OOC: What kinds of magic exist? How does magic work in the context of the story? Be mindful to not improvise and only state what is mentioned in the bot description. Answer OOC. (The part in italics is optional.)

If I'm unsure what kind of roles will work I'll discuss character concepts with the bot, mentioning what I'm considering and asking how that might fit into the story. It's a good way to learn about the lore and integrating your persona with the setting.
