QUEENS

Instagram Influencers.  Zha Dzan states exliplicityly her job is to influence you to change your mind or think a certain way.  The 4th Estate.  Another form of engineer is one whose powers are focused entirely on traversing Heck City and manipulating information, and these are called queens.  Unlike all other dreamers, they are capable of leaving their own pocket dimension and traveling to others and interacting with people, or hiding from them and observing them.  Their abilities tend upon their skills.  The most powerful are extremely dangerous and can attack people in the dream (which usually just results in them waking up), and can damage their physical body, invade their minds and kill, or possess or control them.

They're the planet's hackers, information brokers etc.

Heck City has personality stars, people whose exploits are famous.  Kim Kardashian type figures.  They're paid in pounds and pounds to flounce around in other Schema (they have to be queens of course to do this) and visit people.  There's tons of people who make money this way, and some people are the best at it, their services being highly sought after.  In real life they might look like slobs, but "on night," they are blindingly gorgeous, sometimes charming and mysterious.  Zsa Dzan.  The diamond planes of her face.

These queens have their own schools as well, and these function as sorts of TV channels or major network companies.  Their masters exist half in and half out of Heck City.  Bonded seers function like their regular engineering cousins, and the services they provide all benefit Heck City.  Many of them function as cops or security in public spaces, ensuring the dream remains undisturbed and maintains its shape, function, and integrity.

They direct entertainments, serve as pimps and madames, oversee structural and overal schema integrity.  They keep the system going.  Occassionally the work they do is so important they have to be in Heck City permanently.  In which case they'll be buried in loam and hibernate in waking life, and sleep the whole time.

They also act as hunters for rogue seers.  Since a non-bonded seer in Heck City has so much power to enter people's private spaces, they are extremely dangerous.  Most of the time attacking someone in their schema does nothing but wake them up.  But a rogue seer with enough skill and elan really can hurt someone.  It is these that hunters try to track and stop, like an FBI most wanted list.  Blade Runners.

They act as gossip mongers and agents who bring news, by putting on dreamy plays in a special section of Heck City.  Major news items are dramatized, and seers who specialize as actors do their work here at night, as well as in waking life.  Productions in Heck City are lavish and accurate and up-to-date news items, and actors will take these plays and put on a bastardized, half-true almost incorrect story version in real life, based on the half remembered dreams as a cheaper version for members of the public who may not have any money to sleep or the money to see the Heck City version.  These idiots watch the crappy version and think its true.

scout/spy/explorer/adventurers are called Oronauts.  They map and explore Heck City as it changes.

Hackers are called Terrorists.

Builders are called Stitchers.

Scientists and theorists are called Orologists
