Essence 20 · Science Fantasy

The Essence Nexus

Colliding realities around the Everheart.
A short tour of the setting before your first session.

The setting

Welcome to the Nexus

A palace outside time, ringed by doors. Twenty-one charted worlds touch it. Magic, machines, and living Essence share the same corridors — and your champion chooses which current they walk.

Tone

Science fantasy, not homework

Danger is real

Crossings leave pieces of people behind. Merged physics edits bodies. Silence takes more than it gives. Victory costs something.

Champions are made

You are not the saviour of every world on day one. You start hungry, borrowed, or newly arrived. Rank is earned in play.

Choices matter

Which door you take, who you steady mid-crossing, and what you leave behind — that is the story.

You do not need franchise lore. This world stands on its own.

When are we

Year One of the Bleed

Within a single day, doors appeared — places where a person could walk out of one reality into another and arrive alive. They have not closed.

The Archive dates everything from that day. Three accounts disagree on why: a Calculus Ruin equation that required a door, an Ouroboros purchase from beyond, or Essara coming apart so the Aspects could remain.

Reading the calendar

Year 12 of the Bleed

Year — counted from the day the doors opened
Bleed — the merged weather between worlds
Before — each world kept its own history; none of them agree

A short history

How we got here

Day Zero

The Fracture

Doors open on every charted world. Ferrum logs the first. Concordia logs thirty-one before anyone counts.

Year 1

The shaken

People walk through because standing still is worse. One traveller in six arrives wrong. We call them survivors — wrongly.

Year 1

Memory Echoes

Some “survivors” cannot cross a threshold uninvited. They died in the corridor. The census rewrites itself in a panic.

Year 1

First anchor-ring

A Ferrum crew holds a door open on purpose. Trade follows. So do tariffs, queues, and the argument about who pays.

Years 2–5

Haven cities

Settlements grow around stable doors. Nexus Prime becomes the market where physics, law, and language all compromise.

Year 6

Silence Trials

The Ninth School is proscribed in public teaching. Licensed workings remain — and leave less in the world than they find.

Years 7–11

Charting

Bleed Cartographers map tears. Wild doors still invent themselves. Twenty-one worlds earn a place on the official chart.

Now

Your table

The doors are still open. Essara still cannot enter a living universe whole. Champions still walk the currents.

Nobody at the table needs to memorise this. It is here so you know every grudge is younger than the Fracture — and still sharp.

What you carry

The Four Essences

Essence is the force behind courage, invention, motion, and trust. At the Nexus it flows as four currents — and each has an Aspect who speaks for it.

Strength

Sheena the Unbreakable. Endurance, protection, resolve. Hold the line.

Speed

Stella the Ever-Moving. Motion, change, decisive action. Answer first.

Smarts

Samara the All-Knowing. Invention, strategy, discovery. See the pattern.

Social

Solica the Heartbound. Trust, identity, shared purpose. Bind a crew.

The Essence Mistress

Essara cannot walk in

She cannot enter a living universe without tearing it apart. She sends visions, opens doors, and trusts mortals with the rest. The four Aspects are what remains of her — or what she became. Accounts disagree.

“Sheena gives us the strength to endure. Stella gives us the speed to answer. Samara gives us the wisdom to understand. Solica gives us a reason to stand together.”

Aspect I · Strength

Sheena, the Unbreakable

The part of Essara that gives the multiverse stability. Patient, protective, and stubborn enough to hold when every world says fall.

Current: Strength
Relic: The Unbroken Core
Symbol: A fist protecting a star

“Strength is not measured by what you can destroy, but by what you refuse to let fall.”

Sheena in crimson living armour holding the Unbroken Core — Hold the line.

Aspect II · Speed

Stella, the Ever-Moving

The force that keeps time flowing and lets the multiverse answer danger. Bold, competitive, and already moving while everyone else debates.

Current: Speed
Relic: The Starstep Blade
Symbol: A shooting star crossing a ring

“There is always a moment when someone must move first. Be ready when it becomes yours.”

Stella racing through starlight in radiant golden armour — Answer first.

Aspect III · Smarts

Samara, the All-Knowing

Essara's mind and keeper of multiversal history. Calm, analytical, and secretive enough to ask whether every truth should be used.

Current: Smarts
Relic: The Infinite Archive
Symbol: An eye holding a four-pointed star

“Knowledge reveals what can be done. Wisdom asks whether it should be.”

Samara commanding a field of blue holographic maps — See the pattern.

Aspect IV · Social

Solica, the Heartbound

The living bond that lets individuals, teams, and worlds understand one another. She sees every promise as a bright thread worth protecting.

Current: Social
Relic: The Concord Heart
Symbol: A heart joined to four circles

“No world survives because its people are identical. It survives because they choose to stand together.”

Solica holding the radiant Concord Heart beneath aurora light — Bind a crew.

Geography

A working map of the Nexus

Everheart — the crystal core outside time. Currents meet here. Champions answer its call.

Nexus Prime — the Haven city of markets, anchor-rings, and arguments that never end.

Charted worlds — twenty-one realities with doors someone has walked and written down.

The Bleed — the between. Merged physics, Memory Echoes, and corridors that test what you are.

Wild tears — doors nobody charted. Some were invented by an equation. Far sides have not settled.

The Equation That Outlived Its Makers

Your campaign can stay behind one door or cross all twenty-one. Learn each world when it matters — the Nexus rewards curiosity.

Merged weather

The Bleed

Two materials from different realities do not blend. They agree on an interface — and the interface is where everything interesting and dangerous happens.

Prolonged exposure edits bodies in small permanent ways. Spells are assumptions about local law. In a rift biome, say the assumption aloud before you rely on it.

At a glance

Arcane Flux — ley current in Astran lattice; renews itself.
Ordinary machines often fail mid-crossing.
Phase-shift forecasts work — until the instrument crosses a door.
The Grid-Touched and Valor Reach still argue about what leaked.

How you travel

The Crossing

The door always opens. You get through. The Crossing only decides how much of you arrives.

Anchored

Difficulty 10

Held by a ring, choir, or ember-core. The safe way — and the way you rarely get.

Charted

Difficulty 15

Someone has been through and written it down. The default for a party with a map.

Wild tear

Difficulty 20

Fresh, or invented by an equation. The far side has not settled on where it is.

Destination Essence picks the skill: Brawn, Acrobatics, Alertness, or Persuasion. A shared honest verse steadies Social crossings — the singer rolls last, alone.

What fear leaves behind

Memory Echoes

Frightened travellers can leave a piece of themselves in the corridor. Echoes answer to their names. They remember their families. They cannot cross a threshold they were not invited through.

Echo-Born carry a legal status drafted in a panic. Every Haven city reads it differently. Treat them as people — and as a reminder that crossings are never free.

What to know

Failure never stops the party arriving — it only complicates how.
Clean · Shaken · Scattered · Echoed · Unmade.
Some Origins begin as Echoes that refused to fade.

What it is like to live here

Life at the Nexus

Doors are infrastructure

Anchored doors have queues, tariffs, and arguments about who holds the ring tonight. News arrives sideways — a song from Concordia, a briefing from Meridian, a drydock log from Ferrum.

Kit is a fortune

Flux cells, Mantle shards, and Astran alloy cost more than most Haven workers earn in a season. The loadout on your character's back is often the most valuable thing they own.

Magic is not plumbing

Spellwork is rare, costly, and watched. Silence is licensed by name. A working in the street is a story people tell for years — and sometimes a court case.

The Aspects are politics

Temples, academies, and strike teams swear to Sheena, Stella, Samara, or Solica. Faith here is operational doctrine as often as it is comfort.

Which is why a mobile crew who can survive a wild tear is remarkable. Ordinary folk cannot simply leave. You can.

The world today

Troubled times

Most campaigns begin in the middle of history, not at its climax. Here is the weather when you step outside.

Doors still invent themselves

Calculus Ruin equations keep computing. Ouroboros buys the impossible. Cartographers mark tears that were not there yesterday.

Old tensions, new sparks

Echo-Born status remains contested. Haven cities argue tariffs. Worlds that never meant to meet keep meeting — and blaming the Nexus for it.

Ask your GM which world you start on and what people are afraid of right now.

How play works

At the table

The Game Master

Presents the Nexus, plays everyone you meet, and referees the rules. They are not your opponent.

The players

Each of you plays one Nexus champion — a person trying to matter across colliding worlds. Describe what they do and why.

A typical beat

“The charted door sings off-key. Something waited on the far side.”

Cartographer: I listen for which law changed.

GM: Roll Alertness — this is a Smarts current.

Cartographer: *rolls* Gravity is lying about down.

The GM frames a scene. You answer in character. When the outcome is in doubt, the dice decide.

The dice

How a roll feels

d20 + Skill Die ≥ Difficulty

1

Two dice, one story

Roll a d20 and your skill die. Add them. That total is the attempt.

2

Beat the number

The GM sets a difficulty. Match or beat it and you succeed. Miss it and the story moves anyway.

3

Edge and Snag

Edge rolls 2d20 and keeps the highest. Snag keeps the lowest. Shifts move your skill die up or down the track.

That is the engine. Everything else is your character sheet telling you which die to add.

Who you play

Your first champion

Origin

The world that made you — Havenborn, Starstep Courier, Living Machine, Echo-Born, and more. It shapes how doors treat you.

Essence Role

Strength, Speed, Smarts, or Social — Sheena's Path, Stella's, Samara's, or Solica's. Broad callings, not job titles.

A champion woven from Strength, Speed, Smarts, and Social currents

A concept

One sentence is enough: “a courier who has never refused a wild tear.” Your GM and table fill in the rest.

You start as someone the Everheart noticed — not someone who has already saved it. That is the point.

The story waits

Game on.

You know the Nexus. You know the doors.
Now make someone who belongs in it — and walk through.
