"Come on," I say, "let's go see Li

"Sure," she says, partly letting go. "But Robin, isn't it obvious what you need to do?"

"Huh?"

"About your problem." She taps her toe impatiently. "Or haven't the therapists been giving you the hard sell, too?"

"You mean the experiment?" I lead her back into the Green Maze, cueing my netlink for another firefly. "I was going to say no. It sounds crazy. Why would I want to live in a panopticon society for ten or fifty megs?"

"Think about it," she says. "It's a closed community ru

Enlightenment dawns. "If anyone is after me, they won't be able to get at me unless they're inside it from the start! And while I'm in it I'll be invisible."

"I knew you'd get it." She squeezes my hand. "Come on, let's find these friends of yours. Do you know if they've been approached, too?"

WE find Li

"I had a session with Dr. Mavrides," Li

"Not my cut." Vhora sounds amused, though it's hard to judge. "It's historical. Premorphic, too. Sorry but I don't do ortho anymore, two lifetimes were enough for me."

"Oh, Vhora." Li

"I'm not clear on the historical period in question," I say carefully. To be perfectly truthful, I'd deliberately ignored the detailed pitch Piccolo-47 mailed me until Kay pointed out the advantages of disappearing into a closed polity for a few years, because I was totally uninterested in going to live in a cave and hunt mammoths with a spear, or whatever Yourdon and his coinvestigators have in mind. I don't like being taken for a soft touch, and Piccolo-47's attitude is patronizing at best. Mind you, Piccolo-47 is the sort of self-congratulatory, introspectively obsessed psych professional who'd take any suggestion that their behavior displayed contempt for the clients as projection, rather than treating it as an attempt to work around real social deficiencies. In my experience, the best way to deal with such people is to politely agree with everything they say, then ignore them. Hence my lack of information about the exact nature of the project.

"Well, they're not telling us everything," Li

I feel Kay shiver slightly through my left arm, which is wrapped around her uppermost shoulders. She leans against me more closely, and I lean against the tree trunk behind me in turn. "Like ice ghoul societies," she murmurs.

"Ice ghouls?" asks Vhora.

"They aren't tech—no, what I mean is that they are still developing technologies. They haven't reached the Acceleration yet. No emotional machines, no virtual or self-replicating toolsets. No Exultants, no gates, no ability to restructure their bodies without ingesting poisonous plant extracts or cutting themselves with metal knives." She shudders slightly. "They're prisoners of their own bodies, they grow old and fall apart, and if one of them loses a limb, they can't replace it." She's very unhappy about something, and for a moment I wonder what the ice ghouls she lived with meant to her, that she has to come here to forget.

"Sounds icky," says Li

"How's the experiment meant to work, then?" I ask, puzzling over it.

"Well, I don't know all the details," Li

"What they've prepared for the experiment is a complete polity—the briefing says there are over a hundred million cubic meters of accommodation space and a complete shortjump network inside. It's not totally uncivilized, like a raw planetary biome or anything. There are a couple of catches, though. There are no free assemblers, you can't simply request any structure you want. If you need food or clothing or tools or whatever, you're supposed to use these special restricted fabricators that'll only give you what you're entitled to within the experiment. They run a money system and provide work, so you have to work and pay for what you consume; it's intended to emulate a pre-Acceleration scarcity economy. Not too scarce, of course—they don't want people starving. The other catch is, well, they assign you a new orthohuman body and a history to play-act with. During the experiment, you're stuck in your assigned role. No netlink, no backups, no editing—if you hurt yourself, you have to wait for your body to repair itself. I mean, they didn't have A-gates back before the Acceleration, did they? Billions of people lived there, it can't be that bad, you just have to be prudent and take care not to mutilate yourself."

"But what's the experiment about?" I repeat. There's something missing; I can't quite put my finger on it . . .

"Well, it's supposed to represent a dark ages society," Li

"What are the rules?" asks Kay.

"How should I know?" Li
