The drone drifted through the darkness of interstellar space. It really was alone. Profoundly, even frighteningly alone. It picked through the debris that had been its power, sensory and weapon systems, appalled at the wasteland it was discovering within itself. The drone felt weird. It knew who it was - it was Sisela Ytheleus 1/2, a type D4 military drone of the Explorer Ship Peace Makes Plenty, a vessel of the Stargazer Clan, part of the Fifth Fleet of the Zetetic Elench - but its real-time memories only began from the instant it had woken up here, a zillion klicks from anywhere, slap bang in the middle of nothing with the shit kicked out of it. What a mess! Who had done this? What had happened to it? Where were its memories? Where was its mind-state?

Actually it suspected it knew. It was functioning on the middle level of its five stepped mind-modes; the electronic.

Below lay an atomechanical complex and beneath that a biochemical brain. In theory the routes to both lay open; in practice both were compromised. The atomechanical mind wasn’t responding correctly to the system-state signals it was receiving, and the biochemical brain was simply a mush; either the drone had been doing some hard manoeuvring recently or it had been clobbered by something. It felt like dumping the whole biochemical unit into space now but it knew the cellular soup its final back-up mind-substrate had turned into might come in handy for something.

Above, where it ought to be right now, there were a couple of enormously wide conduits leading to the photonic nucleus and beyond that the true AI core. Both completely blocked off, and metaphorically plastered with warning signals. The equivalent of a single lit tell-tale adjacent to the photonic pipe indicated there was activity of some sort in there. The AI core was either dead, empty or just not saying.

The drone ran another systems-control check. It seemed to be in charge of the whole outfit, what was left of it. It wondered if the sensor and weaponry systems degradation was real. Perhaps it was an illusion; perhaps those units were in fact in perfect working order and under the control of one or both of the higher mind components. It dug deeper into the units’ programming. No, it didn’t look possible.

Unless the whole situation was a simulation. That was possible. A test: what would you do if you suddenly found yourself drifting alone in interstellar space, almost every system severely damaged, reduced to a level-three mind-state with no sign of help anywhere and no recollection how you got here or what happened to you? It sounded like a particularly nasty simulation problem; a nearly-worst-case scenario dreamt up by a Drone Training and Selection Board.

Well, there was no way of telling, and it had to act as though it was all real.

It kept looking around inside its own mind-state. Ah ha.
