Terminology of Significance:
Daylighters - the folk who live closer to the surface. Still in the tunnels, but they go out from time to time. Viewed as low-caste, serfs, by the rest of the tunnelers.
Deepers - The ones who live deep in the tunnels. Never see the sun. Aristocracy.
Scuttlers - Merchant caste. Go-betweens for Daylighters and Deepers, though they probably aren't welcome for long in the deep tunnels.
Tunneler - Catch all term for tunnel-dwellers.
12th Street Station - the local 'hold, where a lot of tunnelers live. Covers sections inhabited by deepers (the station proper) and daylighters, towards the surface.
Fuckoff Cave - Clarion and some of the other powerful deepers can give the residents of 12th Street the old Fuck Off, kicking them out of the hold and making them go live elsewhere. Fuckoff Cave was founded by a bunch of such individuals. It's a cave, but it's totally cut off from the cave system to which 12th Street is attached. The only way to get to Fuckoff Cave is above ground. Fuckoff Cave is equal parts criminal/troublemaker types and religious or philosophical thinkers who were undesirable in 12th Street.
Avenue: Rabbit's mother. Scuttler, now.
Fuse, Tao, and Bar: Rabbit's stepbrothers, aged 14, 13, and 11, respectively. Scuttlers all.

Kray's sister: Something happened to her. Don't remember her name. Speaks to Kray through his mask, sort of.
Wilson the First: The "real" Wilson. The one who founded the Menagerie and built up a reputation. He was willing to kill megafauna, but only if he had no other choice. He was Christine Wilson's love. He died or vanished during a catastrophe that left most of the Menagerie dead, the details of which are unknown.
Johnson, Kim, Smith, Rothschild: Old dead members of the Menagerie. Or at least, likely dead.

Alba, Nugget, Trio: Rabbit's students, all scuttlers

Balls: Deeper Rabbit follower. "Balls doesn't seem to get what you're saying all that while, but he loves the drugs, and you can tell he wants to believe you and follow you with all his heart."
Prim: Deeper Rabbit follower. "Prim has been doing his best advocating for you, trying to get more people to come by and try your crocus fruit, though you have a feeling that it's more than a little because he wants to fuck the pretty women he can get to come to the sermons."
East Harrow: Deeper Rabbit follower. "East Harrow, you're totally confident that all she wants is to fuck you, that as far as she's concerned, you are everything she wants and needs. Though, she might just be confusing you for the drugs."
Chai: Rabbit follower. "Shes not exceptionally unattractive. Shy, awkward, and the things she tells me, her visions, are nothing like the others-- they dont make sense, and Ive never interpreted one correctly. Shes always so sad and disappointed in me. I think shes joined and left my group a half dozen times. She still comes back to me, though. So I must be helping, right?"
Zinc, Bible, Photo, Smirnoff: Daylighter followers. Hooked on the Crocus juice, were supplied by Trio during Rabbit's stay in the deep.
Homeboy: Another such follower, but deceased.
Cast: Chai's father. A successful deeper who deals in a particular kind of phosphorescent moss.
Wisher: Tunnel guard. "Wisher always took guard duty seriously."
Grome: Tunnel guard. "Grome plays music. A two string guitar type thing, hooked to a metal bucket. When she plays, she just comes alive, lost to the music. I didnt want her to lose that. So I refused her entry to the cult; shes forbidden the prepared crocus. I know the visions take so much out of people, they rarely return to their previous passions in the same way. And to watch her move, is such a thing of beauty, I couldnt part with that."
