"Phasers armed and locked on target."
   "Mr. Blair, inform the transporter room
   that you and I will be beaming down to planet surface
   within two minutes. Attention Chance," Data
   continued, raising his voice and thereby activating the
   comm link. "Our phasers are armed and locked on
   you. Unless you respond immediately, we will be forced,
   in this state of emergency, to fire on you.
   Acknowledge or suffer attack. Acknowledge."
   The intership radio crackled to life immediately.
   "Enterprise," came an irritated
   gravelly voice, "this is Captain Tennant
   of the Chance. What in hell do you think you're
   playing at?"
   "I believe," responded Data, "that the
   same could be asked of you, Captain."
   "We're simply obeying orders," shot
   back Tennant, "as part of a confidential
   mission, the contents of which I am not at
   liberty to disclose. Not even to one of the flagship
   vessels of the fleet."
   "Disclosing them would be pointless," Data said.
   "I have no doubt that they are utter fabrication.
   I would assume radio silence is one of those
   orders. One moment, please." Data turned
   to Margolin. "Are we within range of the Forever World
   yet?"
   "Yes, sir."
   "Raise them ... Captain Tennant,"
   Data continued the first conversation, "am I
   correct about the assumption of radio silence?"
   "Yes, you are. And to be blunt, I'm
   jeopardizing the safety of that mission by conversing with
   you. But with the safety of my crew on the line, I
   decided to acknowledge your hail, in direct
   contradiction of my orders."
   "Excellent judgment, Captain," said
   Data calmly. "Am I also correct in
   assuming that Admiral Riker is not there?"
   "That is correct. He beamed down to the
   surface fifteen minutes ago. He told us
   to maintain orbit and radio silence."
   "That does not surprise me."
   "Sir," said Margolin, "we're unable
   to raise anyone on the surface."
   "That also does not surprise me.
   Transporter room, can you lock on any
   life-forms on the surface? If so, I want
   them all beamed up immediately."
   There was a pause as the transporter chief
   ran a quick scan. Then her voice came over the
   comm: "Negative, bridge. Readings are too
   sketchy. If someone is down there and gives us
   coordinates, that's not a problem. But as it is,
   I'd be afraid to try and lock on and bring
   something up. I might get nothing at all, or
   maybe a puddle of protoplasm. There's no
   predicting without solid confirmation."
   "Very well. Mr. Blair," said Data, "with
   me."
   Data crossed quickly to the turbolift,
   Blair right behind him. Almost as an afterthought,
   Data called out, "Chance ... maintain
   position. We will inform you if there is anything you can
   do."
   "Enterprise, would you mind telling us what's
   going on?" came the voice of Captain
   Tennant. "Admiral Riker said that we were being
   commandeered as part of a top-secret mission
   for Starfleet. He even had orders--"
   "I'm sure he did," said Data. "I
   assure you, however, they were forged. You are on a
   mission, Chance ... but it's not on behalf of
   Starfleet. It's on behalf of Admiral
   Riker."
   "What? What in hell is this about,
   Enterprise?"
   "Don't concern yourself about it, Captain
   Tennant. Whether the admiral's mission
   succeeds or not ... either way, you'll never know.
   Enterprise out." And then he cut the
   transmission rather than waste more time.
   After all, the entire conversation might end up
   being moot.
   When Data and Blair arrived on the
   planet's surface, they discovered precisely
   what they thought they would find.
   The bodies of the scientists were scattered about.
   A quick inspection revealed that they were alive, but
   clearly phaser-stunned. Riker must have secreted
   a small hand unit ... perhaps several ... on his
   person. He'd done it in such a way that
   Tennant hadn't known ... otherwise he'd
   certainly have let Enterprise know about it.
   What tissue of lies had Riker constructed?
   Data wondered as he and Blair quickly made
   their way across the compound. Sindareen scheme?
   Romulan incursion? Or perhaps the Ferengii were
   up to their old tricks? There was no end to the
   possibilities that an inventive mind could
   conjure, and Riker's mind was as inventive as
   anyone's.
   Data scanned the entire area and came to an
   immediate realization. "Mary Mac is not here."
   "Which means--"
   "She's with him," concluded Data. "Odds are
   it's an unwilling accompaniment."
   Above them the air swirled and crackled, and more
   than once lightning lanced across the sky. Data
   felt forces gathering around him, as if some
   massive, insane celestial experiment were in the
   works.
   Quickly they ran through the compound, small bits of
   dirt and rock swirling around in whirlpools that
   moved, Data noticed, in opposite
   directions from one another. Somehow that seemed
   perfectly in keeping with the rest of the environment.
   "He's crazy," Blair was
   muttering. "He's completely crazy."
   "No, Mr. Blair," Data replied,
   speeding up slightly. "He's not crazy at
   all. He's merely determined, and certain he
   is doing the right thing."
   The wind grew louder, and Blair raised his
   voice. "And what if he is? How do we know for
   sure?"
   "We don't. But we cannot take the chance."
   They raced to the top of an outcropping. Far,
   far in the distance, the ruins of the city were still there, as
   silent and unproviding of information as they had ever
   been. There below them was the Guardian of Forever.
   The protective force field surrounding it was
   intact.
   Riker, however, was on the inside.
   So was Mary Mac. He had a firm grip
   on her wrist, but now she was struggling with the
   fierceness of her Orion heritage. Her teeth
   were bared, her fingernails flashing. Riker had been
   holding a tricorder, but it had clattered to the
   ground. Data saw that Riker needed both hands
   to keep off her savage onslaught.
   She was shouting something that even Data, with his
   supersensitive hearing, couldn't make out over the
   howling of the winds. And then Data also saw, on the
   large screen that had been erected nearby the
   Guardian, events being played out that were
   horribly familiar. There was Deanna Troi,
   on the floor of her quarters, writhing and gasping,
   and a terrified and confused Commander Riker leaning
   over her, looking more helpless than he ever had in
   his life. On the ground near 
					     					 			by, the fallen
   tricorder continued to record the information with
   precision.
   Data gestured for Blair to follow and the two
   Starfleet officers made their way quickly down
   toward the Guardian.
   Mary Mac swung Riker's arm around and
   clamped down with her teeth. Riker howled in pain
   and slammed her in the face with as hard a punch as
   he could remember ever using. Mary Mac released
   her grip and staggered, wiping at the blood
   trickling down her mouth.
   "You'll destroy everything!" she shouted.
   "This "everything"' has no right to be!"
   "You're not the one to make that decision!"
   "Wrong! I'm the only one!"
   She leaped at him again, a feral
   snarl ripping from her throat. Riker ducked and
   she sailed over him, and he stood quickly, catching
   her in midlunge. Before she could make a
   countermove, he deliberately threw himself
   backward and body-slammed her to the ground. He
   twisted quickly around while she was stunned and, giving
   it everything he had, slugged her on the side of the
   head. The green-skinned woman's eyes rolled
   up into the back of her head, and she went limp.
   Quickly Riker felt under her chin and checked her
   pulse. He wasn't entirely sure what was
   normal for an Orion, but this felt strong and
   firm. Good enough.
   He grabbed his fallen tricorder and forced himself
   to be dispassionate as he programmed it.
   Carefully, he began to calibrate the
   tricorder to the enlarged screen designed
   specifically to display the Guardian's readouts.
   The tricorder would be able to measure the speed of the
   Guardian's actual display against the
   time-delayed playback of specific moments as
   depicted on the screen. Once it was all fed in
   and cross-programmed, the tricorder would be able
   to tell him exactly when to jump through the portal.
   There would still be no guarantee of 100 percent
   accuracy. But it was the only shot that Riker had.
   His determination was to try to leap through as close to the
   actual event as possible. He knew that the
   longer he was back in the Enterprise
   1701-D, the more chance he had of affecting things
   he wanted to leave alone. So he had to bring himself
   as near to Deanna's death as he could without missing
   it ... while leaving himself enough time to do something about it.
   His fingers flew over the tricorder's
   controls, cross-referencing the two displays.
   He programmed in, basically, a countdown.
   When the correct moment was approaching, a small
   green light on the tricorder would snap on. The
   moment that happened, Riker had to leap through
   precisely five seconds later ... a
   built-in delay factor, as he had
   calculated how long the actual, physical
   act of taking two steps forward and jumping through would
   require.
   "Guardian!" he shouted. "The display I just
   witnessed--on my mark, begin again. Three ...
   two ... one ... now!"
   Images began to coruscate across the face
   of the Guardian of Forever. The same dizzying
   blur that Riker had seen before. The
   primary command had been simple: Riker had
   asked to see the history of the Enterprise. The
   Guardian had proceeded to show it--except that the
   display had begun with the first event that the Guardian
   had considered to be instrumental to the creation of the
   mighty starship. Unfortunately for Riker, that
   event had been the invention of fire. Images of
   beings that were barely recognizable as ancestors of
   humanity, clustered around a small pile of
   sparking wood, was hardly what Riker needed.
   Fortunately enough, the Guardian was renowned
   for its speed. In an eyeblink Riker witnessed
   the creation of the wheel, the development of tools.
   They were wonders that, under other circumstances,
   Riker would have been spellbound to witness. As it
   was, he was merely impatient to get past them.
   The tricorder's programming had brought it on
   line as soon as the Guardian began the
   playback. It hummed along silently, matching
   and timing the display. Inside its circuitry, the
   countdown had begun.
   Riker patted the vial that he had hidden in his
   jacket.
   "Admiral!" came the shout from behind him.
   Riker spun, and he saw Blair and Data
   approaching. For a moment he was startled and even
   frightened that they would stop him when he was so near
   to his goal ... and that he would never get another
   opportunity. But then he remembered the force
   screen that was serenely in place. "It won't do
   any good, Dataffwas Riker called. "My
   mind's made up!"
   Data and Blair came to a halt just on the
   other side of the force field. Blair's thick
   fur was blown this way and that in the fierce windstorm
   that surrounded them. Data called out, "Is Mary
   Mac all right?"
   Riker checked the Guardian. Leonardo da
   Vinci was stroking his chin thoughtfully, studying his
   designs for a primitive flying machine.
   "She's fine, Data! She was less than
   cooperative when I forced her, at phaser
   point, to open up the forcefield. I told her
   I'd just stun her and used her handprint and retina
   pattern even if she was semiconscious. She
   chose to remain conscious, hoping that she could talk
   me out of this. And when she realized she couldn't, she
   seized a moment when I was distracted and tried
   to take me out. Damn near did, too," he
   said, rubbing the back of his neck
   ruefully.
   "Admiral, you must turn away from this
   destructive course."
   Riker glanced back at the Guardian.
   Alexander Graham Bell was just informing Watson
   that he needed him, and in an overlapping image,
   Thomas Edison was staring in wonderment at the
   glowing light in front of him.
   "I'm going to save her, Data! For forty
   years, I've been eaten up by the thought that I should
   have done something! She begged me to ... I
   promised that I would, and then all I did was stand
   there and watch her die!"
   "She wouldn't have wanted this, Admiral!
   You're risking everything!"
   "Don't you remember, Data?" called
   back Riker. "The name of James Kirk's
   autobiography?"
   Data needed only a moment to recall it.
   "It was entitled Risk Is Our
   Business."
   "Damn right! I owe Deanna nothing less
   than to try everything! You hear me, Data?
   Nothing less!"
   "Admiral, if you do not come out of there immediately,
   I shall order the Enterprise to open fire and use
   ship's phasers to penetrate the force field! You
   may very well be destroyed if that happens!"
   "And the Guardian might be as well!" shouted
   back Riker. He took a step toward the t 
					     					 			ime
   gate. Seconds before, a Saturn Very
   rocket had been lifting off. Now Zephram
   Cochrane was about to activate the first warp drive
   unit. "Would you do that, Data? Would you risk
   destroying the Guardian? Don't you see,
   Data? You've longed to understand humanity! You've
   longed for a soul! Well, Mr. Data--the
   Guardian is the resting place of all the souls,
   throughout all time! It's God's window on
   eternity! Who are you to destroy it?"
   Andwith icy calm, Data replied, "I have
   already contacted Starfleet, Admiral. Their
   orders were very specific. Protect the time
   stream, no matter what. Deanna Troi must
   die ... and if it takes the destruction of
   God's window, then who better, Admiral,
   to assume that responsibility? After all ...
   I am not one of God's creatures." And
   Data angled his head upward and said,
   "Enterprise ... target the shielding
   directly in front of me. On my command ...
   fire."
   "Don't do it, Mr. Dataffwas called
   Riker with genuine pleading in his voice. "Don't
   kill Deannaffwas
   "I did not kill her, Admiral. But if
   maintaining the integrity of the space-time continuum were
   at stake, I would take her life with my own
   hands. I would derive no satisfaction from it.
   Indeed, the counselor was as dear to me in my own
   way as she is to you in yours. But I am prepared
   to accept that her death is a requirement in the
   natural order of things, and to preserve that order,
   I will do whatever I have to do."
   Data had spoken with certainty and a sense of
   implacable decision. And Riker knew that lines
   had been drawn. "So will I, Mr. Data."
   "Enterprise," said Data tonelessly.
   "Fire."
   From orbit, the mighty phasers of the
   Enterprise cut loose. They struck the force
   field directly above Riker's head. The force
   field sparked and shimmered under the barrage,
   resisting the power of the weapons.
   It was the strongest force field that Federation
   technology had to offer ... on par with the
   deflector shields of the Enterprise herself.
   Furthermore, the Forever World had been equipped
   with its own heavy-duty defense array,
   protected by similar shields. If a hostile
   vessel had shown up, the scientists below could very
   easily have given a very formidable accounting of themselves
   --in all likelihood, blowing the attacking
   ship out of orbit.
   But the Chance had not been a hostile vessel,
   and the renowned and esteemed Adm. William t.
