  “I didn’t disobey. My Ram Odin had the same impulse as the others, to issue the kill order. But he waited a fraction of a second and in that moment realized what the result would be—his own death—so he moved away from me as he said, ‘Obey only me.’”

  “And he completed that order before the other order was completed.”

  “He did. I heard the same order as the others. But I had a previous order to obey only the Ram Odin who was in the control room with me. So I obeyed that Ram Odin, and no other.”

  “And he didn’t tell you to kill anyone,” said Umbo.

  “He told me to pretend that I had obeyed. He told me and the ship’s computers to reveal to no other expendable and no other ship that he was still alive. We should obey all orders that would not harm him, and to pretend we had obeyed the ones that would. We kept him alive, but hidden, until all the other colonies had been founded. Our secret Ram Odin slept in stasis, and so did his colonists, until the ruling Ram Odin died of old age. Only then did I awaken our Ram Odin, as he had ordered.”

  “So there was no conflict,” said Umbo. “He was asleep, and so you could all obey the Ram of Ramfold without any chance of your secret Odin contradicting him.”

  “Our colony started seventy years later than the others. But what is seventy years compared to eleven thousand, one hundred ninety-one?”

  “Your Ram Odin did not follow all the policies of the first Ram Odin.”

  “Ram of Ramfold ordered all the ships to conceal higher technology from their people and allow it to die out, so that it could be reinvented many generations later, in new forms, but without any terrible weapons. Ram Odin of Odinfold gave a different order, and I obeyed him. While I had no choice but to keep the terrible weapons from them, I gave them full access to knowledge of the rest of the high technology of Earth. I told them what subjects they were forbidden to study, and what the penalty would be. I also kept the colonists fully informed of what was talked about among the starships and expendables of the different wallfolds.”

  “Except when that information would have harmed them,” said Umbo.

  The expendable did not answer.

  “You tell them everything that you think they should know, but there are things you don’t tell them.”

  The expendable said nothing.

  “I won’t tell them that you’re leaving things out,” said Umbo. “Because I don’t actually know it.”

  The expendable said nothing, but now, at the other end of the bridge, the door in the side of the ship opened.

  Umbo almost stepped onto the bridge. Then he stopped. “Are you planning to kill me when I step onto the bridge?”

  The expendable said, “I do not kill human beings.” It sounded as if Odinex were proud of not having killed his Ram Odin.

  Again, Umbo almost stepped onto the bridge, but caught himself. “Odinex, am I a human being?”

  “No,” said Odinex.

  “So if you kill me, you will not be killing a human being.”

  “Correct.”

  “Odinex, I am a human being.”

  The expendable said nothing.

  “What is your definition of a human being?” asked Umbo.

  “An organism compliant with the standard human genome, with the normal range of variation.”

  “What is my variation from standard?”

  “You are genetically more different from human beings than a chimpanzee is.”

  “Is that true of all the humans of Odinfold?”

  “No,” said the expendable. “You have their variations, plus the variations from Ramfold.”

  “Are any of the people of Garden human, as you define that?”

  “No,” said the expendable.

  “And by your definition, I’m even less human than everyone else.”

  “It is the definition programmed into me on Earth,” said Odinex.

  “Now let me ask you again. Will you let me cross this bridge safely, enter the ship, and then leave safely when I’ve finished my work?”

  Odinex gave no answer. It was as if the question had not been asked.

  Umbo had studied enough of the programming of the ship’s computers and the expendables that he understood what was happening. “You can’t make a prediction because you don’t know what I intend to do.”

  “Correct.”

  “Can you tell me what to avoid doing in order to keep you from needing to kill me?”

  “Giving you a list of forbidden actions will only make it easier for you to act in a forbidden way.”

  “But not giving me the list makes it impossible for me to avoid doing a forbidden thing.”

  “You can avoid doing a forbidden thing by not entering the starship.”

  “So if you push me off the bridge and I fall and you don’t rescue me, I can’t violate the ship.”

  “That would be one solution.”

  “Is it the one you’re planning to use?”

  “Yes.”

  “Thank you for answering my question honestly.”

  “I tell the truth,” said the expendable.

  Umbo wanted to ask, Now tell me how to get onto the starship. But of course the expendable would see through a ruse like that; there was no point in trying it.

  Besides, Umbo had been studying starship design for the best part of a year. There were things he knew.

  “Odinex, are you malfunctioning?”

  “I am not.”

  “How do you know?”

  “Because my self-auditing software reports that my functions are normal.”

  “Odinex, is your self-auditing software malfunctioning?”

  A long pause. “I do not know.”

  “Odinex, will you run diagnostics on your self-auditing software?”

  “I will when you are not present.”

  “I am not a threat,” said Umbo, annoyed now that the expendable wasn’t going to be as easy to control as he had hoped.

  “You are a threat,” said Odinex.

  “On what basis do you regard me as a threat?”

  “The person you call Swims-in-the-Air has told me you are a threat.”

  “But that person is not human.”

  “She is more human than you are,” said Odinex.

  Umbo pulled the knife from his clothing and displayed the jeweled hilt. “Do you recognize this knife?”

  “Yes,” said Odinex.

  “Are the jewels in the hilt faithful copies of the jewels of control?”

  “Yes.”

  “Smaller, but faithful.”

  “Yes.”

  “Do they function like the jewels of control?”

  “Yes.”

  “Because I possess these jewels, can I be certified as commander of this vessel?”

  “In the absence of any other commander, you could be certified.”

  “Is there another commander?”

  “Rigg Sessamekesh is the commander of all the vessels on the planet Garden, and all the orbiters, and all the expendables.”

  “So these jewels cannot be used to take his place.”

  “He is not dead,” said Odinex.

  A dark thought came into Umbo’s heart. He drove it away. “One of these jewels is the jewel of control for this ship alone, yes?”

  “Yes.”

  “Can I use it to be certified as the commander of this vessel, as long as I don’t contradict the orders of Rigg Sessamekesh?”

  “With his consent, yes.”

  “But he is not human,” said Umbo.

  “Human status is not required to be in command of the vessel.”

  An interesting loophole. But there was another. “I am a descendant of Ram Odin.”

  “After generations of intermarriage, everyone now alive in both Ramfold and Odinfold is a descendant of Ram Odin. Everyone is a descendant of all the colonists. After eleven thousand years, it could not be otherwise.”

  “Was Ram Odin human?”

  “Yes.”

  “Were his childr
en human?”

  “Yes.”

  “What were their names?”

  Odinex listed them, and then said, “I see your point.”

  “Were their children human?”

  “Yes. I see your point.”

  “At which generation did they cease to be human?” asked Umbo.

  “I see your point.”

  “But do you accept it as a valid definition of humanity? As the primary definition?”

  A pause. “I do.”

  “So the argument of genetic continuity is superior to the argument of accumulated genetic drift and alteration.”

  “It is,” said Odinex.

  “May I come aboard?”

  “You may.”

  Umbo stepped onto the bridge and strode briskly across.

  He did not so much hear the expendable come along behind him as feel the wind of his coming. Then he felt Odinex’s hands on his back, picking him up and shoving him toward the edge of the bridge.

  Umbo shifted in time to a few seconds earlier. Now he was standing at the point where Odinex had taken hold of him, but now Odinex was two meters farther back on the bridge, preparing to seize him, while Umbo’s previous self was one meter away, looking surprised to see this new version of himself.

  The expendable was even more surprised, though his face showed nothing.

  “Which of us do you need to kill?” asked Umbo.

  The earlier Umbo turned around and faced the expendable. Now that Odinex was not throwing Umbo off the bridge, that version of Umbo did not need to time-shift. Both Umbos continued to coexist, standing side-by-side on the bridge.

  The Umbo who had shifted now stepped back two paces and shifted again. Now he could see both earlier versions of himself facing Odinex on the bridge. “Is this how Ram Odin was duplicated, Odinex?” asked Umbo. “Obey no one but me, expendable.”

  The expendable stood transfixed.

  Umbo turned and walked swiftly through the door into the ship.

  Then he ran.

  He knew the layout of the ship, knew exactly where the control room was, and knew, from Rigg’s account of it, what to do with the jewels. What he didn’t know was which of the jewels controlled this ship.

  He stood at the verifying machine, holding the hilt of the knife into the field. “Is the jewel of control for this vessel present here?”

  “It is,” said the ship’s computer.

  “Rigg Sessamekesh gave me this knife,” said Umbo. “I take command of this vessel as Rigg’s subordinate.”

  There was a slight hesitation. “Did Rigg authorize this procedure?” asked the ship’s computer.

  “Is this the jewel of control?” asked Umbo.

  “Yes.”

  “Did Rigg Sessamekesh give this jewel to me as part of the knife?”

  “He did.”

  “I take command of this vessel as Rigg’s subordinate.”

  Another hesitation. “Certified.”

  “Command all expendables attached to this ship to obey me and cause me no harm.”

  “Done.”

  “Is the expendable still on the bridge with the other two copies of me?”

  “No,” said the ship’s computer. “He killed them both and is on his way to this place.”

  Umbo shuddered. “Command him to come into this room walking backward. He is forbidden to look at me.”

  Moments later, Odinex backed into the room.

  “Stop,” said Umbo.

  The expendable stopped.

  “This ship, and all the equipment of this ship, will hereby define ‘human being’ as ‘organism descended in an unbroken line from the colonists of one or more of the ships commanded by Ram Odin on their voyage to Garden.’ Do you understand?”

  “Yes,” said the expendable.

  “Yes,” said the ship’s computer.

  “Am I human?”

  “Yes,” they both answered without hesitation.

  “Who can change this definition?”

  “You can,” said the ship and the expendable.

  “Let one speak for both,” said Umbo.

  The ship’s computer fell silent.

  “You and Rigg Sessamekesh can change this definition,” said Odinex.

  “Who else?”

  “No one.”

  Umbo knew this was not true, but also knew that the computers couldn’t lie.

  “Is there a procedure by which someone else can gain the authority to change this definition without my or Rigg’s consent?”

  “Yes.”

  “Can you disable all procedures that would allow us to be superseded?”

  “No.”

  “Can I disable them?”

  “Yes,” said the expendable.

  In this situation, Umbo didn’t trust simple answers. “And if I do, what will be the consequences?”

  “The orbiter will obliterate all life within this wallfold.”

  Umbo sighed. “I will not attempt to disable those procedures.”

  Odinex said nothing.

  “Turn and face me, Odinex,” said Umbo.

  Odinex faced him.

  “You killed me twice today.”

  “I killed expendable copies of yourself,” said Odinex. “They came into existence because you jumped back in time, and by appearing in their presence, you changed their actions so when they reached the point in time when you time-shifted, they did not time-shift, and therefore they did not disappear.”

  “How long might such duplicates continue to exist?” asked Umbo.

  “Until they die.”

  Umbo had never thought of this possibility. But it gave him a better understanding of how the duplicate ships had come into existence at the beginning of the human settlement of Garden.

  “How did you kill them?” asked Umbo.

  “I broke their necks and cast them off the bridge.”

  “You are forbidden ever to destroy copies of me or any other time-shifter, without specific instructions to do so.”

  “And which copy should I obey?” asked Odinex.

  “The most recent one.”

  “And how will I know which one that is?” asked Odinex.

  “I’ll try to make sure it never comes up.”

  “That would be best.”

  “Odinex, show me everything on this ship that is not included in the plans that I studied in the library near the Wall.”

  “The plans are complete.”

  “No they’re not,” said Umbo. “They don’t show, for instance, where the spare copies of you are stored.”

  “Intact copies of me are not stored anywhere. If this module fails, then a new one is assembled from the parts in parts storage, which is clearly labeled in the plans.”

  “What triggers the creation of a new expendable?” asked Umbo.

  “A death signal,” said Odinex. “A request for duplication. Loss of higher functions in the present module. Failure to communicate at any level for ten hours.”

  “Who can issue the request for duplication?”

  “The existing module. The certified commander of the vessel and all superior officers.”

  “Thank you,” said Umbo. “Are the duplicates bound to obey all orders previously given to the earlier copy?”

  “Yes,” said Odinex. “We are memory-identical.”

  “Am I human, Odinex?”

  “You are.”

  “Is that what you’ll report to the Visitors when they arrive from Earth?”

  “They will get a full memory dump of these events, along with all others,” said Odinex.

  “They’ll see me make copies of myself by time-jumping?”

  “Yes.”

  Umbo wanted to grin, but restrained himself. Let the Visitors chew on that.

  Then his pleasure faded. Seeing Umbo time-shift might well be a death sentence for Garden. To see someone suddenly pop into existence behind himself, and then again, so three copies exist at once—that wouldn’t exactly reassure the humans from Earth.
r />   Well, it’s not as if they weren’t going to destroy Garden anyway. They’ve done it nine times already, and until now without any provocation from time-shifters.

  It’s hard to imagine that I’ve somehow made the destruction of Garden worse. Will they say bad words while they wipe out all life on Garden? Will they throw stones at the corpses?

  “Odinex, the jewels of control are not mentioned in the plans of the ship, or the computer manuals.”

  The expendable said nothing.

  “Consider that to be a question, and answer me,” said Umbo.

  “The jewels are thoroughly explained in the plans and manuals.”

  Umbo thought for a moment. “Under what name are they explained?”

  “‘Remote storage and transfer of the ship’s log.’”

  Umbo held up the knife and looked at the hilt. “These jewels are the log of each of the nineteen ships?”

  “Yes.”

  Remembering what he had read, Umbo said, “So each jewel contains a complete record of all actions and observations made by all the computers aboard that particular ship.”

  “Yes.”

  “Including all the actions of the Remote Expendable Action Modules.”

  “Yes.”

  “How recent is the information on each jewel?”

  “The jewel that holds this starship’s log was updated just now when you certified.”

  “And the other jewels?”

  “The jewels carried by Rigg Sessamekesh were updated when he certified himself as commander of all the vessels.”

  “And the jewels on this knife?”

  “They were updated when you passed through the Wall.”

  The Wall was certainly a lot more than a barrier between wallfolds. All human languages, and an update of all the ships’ logs. Umbo thought through what this might mean. “When a jewel updates, is it a destructive or a cumulative update?”

  “Cumulative.”

  “So if I were to time-shift and enter a Wall in an earlier time, the information recorded from the later time I came from would not be erased by the update that it subsequently gets in the earlier time.”

  A momentary pause. “I have parsed your question and I can say, Yes, the information from a future time would not be erased by updating the ship’s log remote storage and transfer unit by passing into the Wall in an earlier era, as long as the time-shifter carried the log with him into the past.”

  So the jewels would not suffer data loss by passing through the Wall and being updated in a back-shifted time. “If Rigg or I take a copy of the ships’ logs through the Wall when the Wall has been made passable according to Rigg’s command, is the log still updated?”
