The World

Greylight 2142 is a live action game set in a cyberpunk world, where you can experience oppression, greed, ambition and loss. In this world, magic has awakened and is real.

Diffraction

Diffraction is an evening event in the city block GR-L8, called the Greylight district, a small part of a big megaplex. People go about their own day to day lives and struggle with the problems of a dystopian cyberpunk world.

Technology

A cyberpunk, transhuman fantasy, in which technologies like Cyberware and Conciousness transfer are not fiction any more.

Human Types

Through the emergence of magic, new types of humans were created - the Rifters were an random emergence, an accident, causing a global crisis, whereas the Ascended were made by the most wealthy individuals to be able to use magic and be perfect .

Magic

Magic has awakened in the world, giving those who are gifted unimaginable powers. Regulation of this has become key, making sure these gifts are only used by those who are wealthy enough to afford it.

Androids

Androids - mindless humanoid robots - started to become sentient in the awakening, causing questions about their rights and how they should be treated.

The Game

Visit the district GR-L8 and experience the Greylight world: Freestyle your game, experience the crowded city center, engage with corporation schemes, relax in the garden, eat at the noodle bar or just watch the buzz of the district.

The event takes place in the “Greylight Prelude” location with all its charm and grit.
The district is open for everyone: team members, previous players, newly interested participants and long-time watchers who first want to dip their little toe into the Greylight puddle.

Experience

The core experience should be to exist in the cyberpunk city - we will provide the world and backdrop for the drama you bring yourself. There will be some plot you can participate in, but you can also ignore it without any problems.

The larp is set in an alternate timeline of Greylight - on the other hand some things are the same as in The Prelude, some things are completely different. Occasionally, characters from the Prelude will exist as NPCs, but otherwise existing characters are not allowed.
No one is allowed to play their character from one of the other Prelude Runs.

Existing costumes, however, may of course be used.

The kind of experience depends strongly on the way of participation you choose:

Join the open game (free characters)

The default: players come with their own character and do their own thing. This is primarily about experiencing the world, bringing your own game - and the plot allusions we provide.
Characters can come from anywhere in the Greylight world and pursuing their own goals.

Previous participants have the option to continue their existing character's story

A few month have passed, since the last event. Try to avoid playing on fixed timelines, play what feels right.

Play in a faction

Players can sign up for one of the existing factions from the Greylight lore. These have a number of existing roles (e.g. manager, drug cook, ...), but no pre-written characters. Faction members will be given the opportunity to communicate and plan their game in advance via Discord. They will also be expected to read and follow the faction's design paper beforehand. (Will be provided)

The preexisting factions all come with their own game experiences. These will be planned with the people in charge.

Examples:

Iagatomi: Cataloging and acquiring suspicious androids.
Falcon Security: Providing security and oppression (especially to Rifter characters).
Everlive: Require security and possibly an "empty" body. Offer consciousness backups and manipulation.

You can find the existing Prelude factions available at Diffraction down below.

Citizens of the District

If you want to play a citizen of the Greylight district, you are free to bring your own character concept, but will have the option to connect with your neighbours beforehand. You will have to be a little more careful to create a character that actually fits in.

Your own Group

Players can come with their own character group. In some cases we can even provide them with a space for it. Whoever wants it, can ask for it, and the first ones who ask for it (and whose concept fits reasonably well) will get it.

All factions are intended to be a point of interest and provide some form of gameplay. Some of the factions are essential to the game, in which case they will will be led by an NPC - a team member, or a player with prior experience. Each faction must have at least one person who has played Greylight before or is on the team and therefore knows the faction a bit. No special plot will be provided for the factions, but there exists enough lore to generate play from within.

what to play?

Character Types

You can choose from 5 different character types to play. Each character type comes wich certain requirements and themes.

Humans

about 70%

Short description

Humans make up the majority of the population and can be found in all places where life can thrive. They can be found in all social classes with all kinds of alignments.

Themes

Humans don’t have special themes associated with them.

Playing as a human is the default choice.

Mages

about 2-3%

Short description

With “The Upturn”, magical power came into this world - some people were bestowed a large amount of power, no matter where they were from or what their place in the world was. They discovered their ability to manipulate this new fabric of reality. Their magic is ritualistic, following certain learned rules.

Usage of magic is highly controlled and every mage needs to be registered for all their capabilities.

Themes

Power, Responsibility, Exclusion

Playing as a mage will be limited, and has to be approved by the Greylight team.

You can find costume and makeup requirements in the Style Guide. You'll get acces to the detailed Mage Design Paper after you have been assigned the Mage role on our Discord server.

Rifters

about 15%

Short description

After an event called “The Rift”, a large amount of humans worldwide have developed neon spots on their face and hands. With these they can form a magical connection of emotions and thoughts. Ostracised and excluded for a long time out of fear, they became outcasts before being slowly integrated back into society.

Playing a Rifter means you’ll experience that oppression first hand, but you’ll also be part of a strong and loyal community of like-minded beings.

Themes

Discrimination, Identity, Community

Playing as a Rifter comes with detailed makeup requirements.

You can find costume and makeup requirements in the Style Guide. You'll get acces to the Rifter Design Paper after you have been assigned the Rifter role on our Discord server.

Ascended

about 2-4%

Short description

“Ashen are not born - they are made” -- that is true - and usually there was a huge amount of credits involved. They call themselves the Ascended but are often refered to as Ashen. They are genetically engineered super-beings, all capable of wielding magic and all projecting an aura of presence and authority. That also makes them the most ruthless and arrogant capitalists in the world.

Playing an Ascended means you´ll be a figure of authority wherever you go. You’ll look down on everyone else, and always be involved in cutthroat interactions with other Ascended.

Themes

Hubris, Discrimination, Intrigue

Ascended characters can only be played after contacting the organizers.

You can find costume and makeup requirements in the Style Guide. You'll get acces to the Ascended Design Paper after you have been assigned the Ascended role on our Discord server.

Androids

about 2-3%

Short description

Mass-produced as a cheap workforce, a small percentage of the robots have started to awaken, thinking for themselves and eventually getting at least very basic rights, though still being heavily oppressed

Playing an awakened android will be a very tough experience - you will be oppressed in a lot of ways, and will have to learn about the world around as well as within you.

Themes

Self-Discovery, Oppression, Belief

Playing as an Android comes with sepecific costume requirement.

You can find costume and makeup requirements in the Style Guide. You'll get acces to the Android Design Paper after you have been assigned the Android role on our Discord server.

where to play?

Factions

You can choose an affiliation of different factions to play. Every faction has their very uniqe themes and requirements.

Iagatomi

Corporation

Short description

The largest manufacturer and maintainer of electronics and androids. They are trying to control the spread of the android awakening.

Playing part of them puts you smack in the middle of all the issues regarding androids - maintenance technicians who directly work with them to suppress their development, internal investigators who try to find out if someone got too attached to the subjects, etc.

Themes

Suppress Development of others, Modern Slavery, Subversion

Read More

example character outline

Maintenance Technician who is a huge tech buff and who has recently been thinking more and more about how suppressing android awakening might be wrong.

Management role who has been overwritten and replaced by megacorp to serve as a mole within the corporation.

Security Officer who originally applied at Falcon Security but was rejected and now wants to show them what they are missing out on.

Internal Investigator who becomes too drunk on the power they possess and start abusing it.

Everlife

Corporation

Short description

They are a local, small corporation manufacturing mag-tech equipment and handling the consciousness transfers in the district.

As part of Everlife you will have to make a lot of very hard and complicated decisions - lately, business has not been running well and something needs to be done to secure the corporation's future. Where will you turn?

Themes

Responsibility, Moral, The Price of Progress

Read More

example character outline

The Assistant, who thinks the corporation should focus on its roots, where ethics where still something that was considered in the day-to-day business.

The Researcher, who wants to get behind the mysteries of magic, combining it with science and enhancing humankind.

The Transfer Technician who has lost their grasp on humanity and devolves into meaninglessness.

Citizens

Street

Short description

The people living in the Greylight district are the ones most affected by all the struggles. They have no power here - but they have each other.

Playing a citizen will mean that you are part of a community that is a playball of the big players - they don’t have a lot of control over their own life and every bit of control they have has to be earned. They will have a lot of dramatic play with each other - their focus are the personal stories and relationships with the others.

Themes

Ambition, Community, Survival

Read More

example character outline

Restaurant owner who knows they will lose their restaurant if they can’t make the next rent.

Teenager who has long dreamt of the freedom the outlaws in the gangs must enjoy, who tries everything to be part of them.

Mage who is keeping their powers a secret from everyone, as they know it will cause troubles for their family.

Depressed store intern who wants something bigger in life and tries to get out of this shithole.

Transference

Street

Short description

A small tattoo studio run by local Rifters. Though beneath the glowing neon sign over its entrance there is more than just place to get your neon ink. It is an important community hub for all Rifters of the district. Here is where their culture lives. Here they can meet up, no matter if they are Kror or Waver. Tattooists are important community facilitators for all Rifters, and this is where they work.

Playing a character in the tattoo studio means that you will generally have a very social play. You will know many people and many people will come to you. It also means that you run a business and will actually need to engage with players and "tattoo" them.

Themes

Culturual Appropriation, Capitalism, Two sides of a coin

Read More

example character outline

The old Tattooist, unwilling to give up their craft.

The artist who sees their tattoos as an artform and their customers as their canvas.

The only human who wants nothing more than to be a Rifter and tattoo with neon, but is forbidden from it.

Galen Medical

Street / Corporation

Short description

A small corporation which offers health services to rich and poor alike. “Humanity” is one of their founding pillars.

Being part of them, you’ll be someone who places their trust into higher ideals than themselves, you’ll be an optimist who thinks they can change the world to the better. You might be a First Aid Officer, helping when the need is most dire, fulfilling emergency contracts (customers who activate emergency distress beacons) and making sure folks get the care they need or a doctor stationed in the HQ, who helps the poor and also the rich and famous.

Themes

Altruism, Care, “Defiance against the Status Quo”

Read More

example character outline

Nurse who has a drug addiction and has to decide between their addiction and the clients' health.

Doctor who knows how important keeping the paying clients happy is, but frequently has to defend that sentiment.

Nurse who gives out free help in their spare time to people on the street who would not be able to afford it.

Falcon Security

Corporation / Crime

Short description

Falcon provides A-Level security in the whole Greylight district. That is - for all areas they are paid to “protect”, or at least “squeeze offenders for their last credits”.

Playing a character in Falcon means you’ll be often out on the streets, patrolling and making sure everyone is safe - well, at least that everyone is punished properly. Falcon always has to strive a balance - push the street too hard and they’ll push back - push it too light and they’ll erupt.

Themes

(Ab)use of Power, Belonging, Despotism

Read More

example character outline

The Rifter street cop, who tries to outrun the prejudices cast upon them and become a respected member of the Force.

The naive dreamer who became part of Falcon because they believed they can be a force for good, who is now confronted with reality.

The detective who has done this job long enough to know that its a give and take, that sometimes one just has to look the other way.

The ambitious detective who abuses their power over others and makes sure those who “wrong” them end up on the wrong side of the law.

BMCI

corporation / crime

Short description

The BMCI (Bureau of magical cooperation and investigation) is the only provider of magical oversight in the megaplex. They are responsible to find and deal with unregistered magic and investigate unlicensed usage of magic.

Playing a character in the BMCI means that you will have a lot of power at your disposal (magical and legal). You will play closely together with other investigators and will have intrigue as well as investigation play.

Themes

Success and Failure, Power Abuse, Control

Read More

example character outline

The senior magical investigator who is laser-focused on their task as the stakes are high.

The magical investigator who knows they can't be promoted and focuses on their ascended lifestyle persona instead.

Street Gangs

Crime / Street

Short description

As part of one of the Diffraction specific street gangs, you’ll play those who are outside of society and live in their own dark corner of the district. Unwanted and feared by society at large, they still enact a certain attraction to a lot of the “normal” citizens of the district.

Their exclusion brings a strong community to them, and through shared experiences they have created their own street culture.

Themes

Discrimination, Camaraderie, Freedom

You can create your own streetgang group with some friends for the Diffraction. Your concept has to be approved by the organizers.

example character outline

The young hotshot who wants to prove themself and will inevitably do something very stupid.

The old leader who has seen too much pain and suffering in their lifetime and wants to use their authority to convince their comrades of a peaceful future.

The new gang member who got in for their quick thinking and incredible strength, but often is excluded based on their past.

Chrome Marauders MC

Street / Crime / Biker Gang

Short description

The Bikers are notoriously anti-everything -- anti-magic, anti-Rifter, etc. They run a protection racket on the citizens but also operate a small workshop for cyberware maintenance.

Playing a biker will put a strong code at the centre of your being. You’ll be part of a war of ideologies that splits the group apart and your means of communication are usually physically in nature.

Themes

Discrimination, Old vs. New, Camaraderie

Read More

example character outline

The young prospect who tries to understand the struggle within the biker gang, and will be forced to take a side to become a full member.

The President who knows that eventually the old way will become the destruction of the gang, but also wants to uphold the core beliefs of the bikers.

The mechanic, who only wants to do their work and will become a puppet of other agents that want to take a look into the inner workings of the gang.

 

Larp Style

Themes

The game draws on many different themes - some of them from classical cyberpunk worlds, others from the unique issues that a sci-fi fantasy world brings.
Every group and character will have their own themes, but the main themes pervading the game are:
Discrimination, Oppression, Consequences

Safety

There will be a dedicated offgame room and the organizers will always be available in case of emergency. For more information, look up our Code of Conduct.

Characters

All the players create their OWN characters based on a Greylight faction or outside of it, but within the lore of the Greylight universe. No previously played characters from one of the Runs are allowed! (of course you can reuse your costume)

Sex & Gender

We want a world where everyone can be badass. There are no clear roles or even rules for different genders and society has progressed to a point where what would be considered a liberal view nowadays is the norm. Therefore, your character's gender will pose no boundaries on how you express yourself in terms of costume.
Traditionally, classical Cyberpunk aesthetic is known for a hyper-sexualized aesthetic, especially of women. This is something we clearly do not want to be a theme at Greylight 2142. In our world, everyone can dress any way they want and nobody will interpret any sexual intention into it. Please consider this when putting together your costume - aim for expressing your style and identity, not at appearing hot. Furthermore - there is no defined beauty standard - everyone has their own style.
