Caste

Each of the castes is conditioned to wear a particular colour (listed beside the caste names below). This means that your clothes must obviously be primarily that colour, for example: an Alpha player may wear a yellow t-shirt with a black design on the back as it is mainly yellow, but they would not be able to wear a black shirt with yellow cuffs as this would make them look like an Epsilon. It must be noted that each caste is conditioned from birth to despise wearing the colours of other castes and therefore would not even be able to conceive disguising themselves as a member of another caste. White is another colour that you are conditioned not to wear.

Alpha- Yellow

Alphas! Welcome to a bright new future! A future conceived by you! As Society's sole innovators everyone relies on you. Yes, you! Bow to no man as you create ground-breaking theories and solutions to today's problems, after all, you're the only ones who can. Leave the nitty-gritty to the Betas and concentrate on forming world changing ideas. Don't worry about your lack of social skills and your obsessive nature: who needs friends when you've got a brain this big, right? Find your place in Society.
To reflect their mind-bending problem solving powers Alphas have the ability"Spark of Genius", this can have two effects: One, it allows an Alpha for one clue to a plot related puzzle during a game. Two, it allows the Alpha to create an entirely new item/ theory/ idea, this becomes an 'Concept' which can be given to Betas to implement as a 'Blueprint'.

Beta- Green

Betas! Welcome to a bright new future! A future designed by you! As our leading painters, doctors, engineers, architects and scientists, you shape our Society for the better, and have the know-how to turn the whimsical ideas of the Alphas into a reality! Society will marvel at your works of literary, musical and scientific mastery. Be the face of the Society's thinking community! Find your place in Society.
Betas have the ability "Spark of Realisation" which allows them to turn an Alpha's 'Concept' into a 'Blueprint', from this 'Blueprint' you will be able to produce whatever idea was put forth in a tangible way, be it: composing a concerto, writing a book, creating a new type of battery or producing the worlds first hope-powered sniper rifle.
Betas can also take equipment and reverse-engineer it into an Blueprint. They can also use this on more creative things such as art and expression.

Gamma- Red

Gammas! Welcome to a bright new future! A future organised by you! Leave the high thinking to Alphas and Betas: leave the dirty work to the Deltas and Epsilons. You, yes you, are the ones tasked with keeping this whole Society running. With your wonderful ability to fit in to almost any task, find yourself at the centre of attention. Keep a cool head and a calm mind in a crisis because if anyone can sort it out, it's you! Without you where would everyone get their paperclips! Find your place in Society.
Gammas have the ability "Spark of Competence" which allows them to attempt any skill check even if they are untrained. For administrative purposes they can also read and write all of the five caste-specific written languages. Gammas are always around to give it a go.

Delta- Blue

Deltas! Welcome to a bright new future! A future maintained by you! You keep our factories, workplaces and power plants running. Without you how would anyone get any food, heat or listen to Tammy and Cargo Beta's daily talk-show! Trained from before birth to work any and every form of machinery, from forklifts to pistols to intergalactic cruise ships, you are the mechanical backbone of Society. It may be dirty but it sure is vital. Find your place in society.
Deltas have the ability "Spark of the Mechanist" meaning that they may use any non-prototype item in the game, ignoring critical fail effects.

Epsilon- Black

Epsilons! Welcome to a bright new future! A future powered by you! You may not be the smartest or the most adaptable but darn you're tough! Chosen specially to do the tasks that the more fragile castes would soon tire or die from, this Society would be nowhere without you! You are our miners, boiler operators, street sweepers and radioactive-volcano-planet explorers! No one cares that you just lost your arms, least of all you! You get the job done! Find your place in Society.
Epsilons have the ability "Spark of Resistance" meaning that they have no death count and as such will never bleed out hitpoints when on zero or less. You are also more resistant to pain and trauma.
