Chapter 1

"The Snap"

Xander and Angel ran through the sewers after seeing the flash of light signifying the Master's freedom. 'Damn it! If the Master is free that means….. No! Can't think like that, not now' Xander thought as he ran following Captain Broody. As he was running he felt a tightening in his chest as desperation kicked in despite his best efforts. He was getting a vibe that tonight something was going to change, and maybe not all bad. 'I hope that's not just optimism thinking,' Xander pleaded mentally.

They entered the Master's former lair. Xander could tell instantly that the Master had been down here a LONG time. The massive cobwebs, bleached skeletons, and ancient style torches proved this. Not only had that but the whole lair just stunk with evil overlord vibes. Then he saw it. His worst fears were true. He saw Buffy lying face down in the pool of water, limb and dead. Angel rushed over to check her, to see if there was any hope.

"She's dead, there's no heartbeat," Angel said calmly having already come to terms with Buffy's death before it even happened.

"No! I mean if she drowned there's a chance, she was in the water right, so we can do CPR!" Xander exclaimed knowing he was grasping for straws. He wasn't ready to give in to the death of the girl he thought he loved. The tightening in his chest increased, if possible.

"I guess it's possible, but you have to do it," Angel replied," I've got not breathe." He added when he saw Xander's confused look.

"Ok, I'll do it," Xander answered. 'Of course the first time I get anything close to lip action with Buffy is to save her life' he half-mourned in his head. He hurried over to Buffy and began CPR. He tilted her head back to breathe for her and then started the compressions. 'Come on Buffy! You have to live! The world's lost without you, whose gonna kill the Master!' he thought as he began to tire slightly from the compressions.

However, after the third or fourth set of compressions Angel began to lose hope. "It's hopeless, the prophecy said she would die and she did. There's nothing else we can do."

"No… I've got to keep trying… it's our only hope… she will live." Xander said between his pants of effort, although Xander was fighting to keep the same doubts from his own thoughts as well.

Then Buffy's eyes fluttered, she coughed up the water, and said weakly, "Xander," in response to seeing him holding her after saving her life. Xander replied," Welcome back, you're alive," trying to convince himself more than anything that it wasn't a dream. "Where's the Master?" she asked still groggy from her near-death experience.

This time Angel answered, "He escaped; he's on the topside now already." He was quiet, still guilty over his word about reviving Buffy to be hopeless.

Buffy, however did not notice and smiled warmly and said, "Angel," her voice having more strength now with her slayer healing to thank.

"Crap…" Jenny said as saw the people walking in the field across from them, "They aren't going to the bronze…"

"Huh, what then where…?" Willow asked as she looked around. Then she saw the people, the rather demony-looking people. "Oh…" both Jenny and Willow turned on their heels to see several vampires walk up between the girls and the door to the school. 'Oh no! We aren't going to make it!' Willow thought as a weird feeling grew in her chest as she wished herself to be anywhere but here.

'Bam!' they heard behind them and turned again to see Cordelia's car plow through the vampires. They were slightly awestruck at her divinely inspired timing as she rolled down the window slowing down. "Get in! Come on!" the Queen C of Sunnydale yelled quickly motioning for emphasis. They shook off their shock and rushed into her car. However, a vampire took advantage of the car's stillness and jumped on top hoping to attack them from above. Sadly for the vampire, a panicked teenager is not someone whose car you want to be on top of when you scare them again.

Cordelia screamed and slammed down on the gas pedal. This resulted in the vampire taking an impromptu flying lesson. Once they were free of extra passengers, Cordelia turned to Jenny and Willow and asked, "Where are we going?" calming down slightly as she cleared the school parking lot.

"Um…the library…" Willow answered.

"Oh, Come on!" Cordelia yelled as she made a U-turn practically on two wheels, nearly terrifying her passengers to death. They reached the school moments later, knocking vampires left and right like a snowplow, showing no sign of slowing down at all as she neared the schools entrance.

"Um, we usually walk…" Willow said right as they rammed through the doors, "But this works too." She felt that feeling in her chest increase as they hit them her dread increasing.

They helped Buffy up and she was able to stand on her own amazingly. "Hey, Buffs, you need to take it easy" Xander said, worried about her after her brush with death.

"No, No, I feel strong, stronger than ever really," Buffy replied, a cocky smile crossing her face as she realized it. She started to leave but Angel stopped her.

"Buffy, you can't do this, you die and we may not be able to save you again," Angel said, and then leaning in whispered in her ear, "I can't lose you again."

"No, Angel, I have to do this, I can do this, and you can either get out of my way, or help." The slayer spirit showing completely, Buffy was different now, surer, more predatory Xander noticed. He worried that her death had changed her.

"Okay…" Angel gave in, thoroughly cowed Buffy's words.

Xander stuck in now, "Okay, Buffy, you win, but we're helping and we need to go now if we plan to prevent hell on earth." Knowing that he couldn't convince her to back down but wanting to make a difference hoping her could keep her from dying.

"Alright then let's go, I gotta vampire to kill." Buffy replied as she pushed past Angel and started out the lair, with a visible confidence in her step, "Come on!"

As they drove through the halls Willow was starting to feel weird, the feeling in her chest deepened as her terror grew. 'Ohh, why does my brain have to move so fast' Willow thought mournfully as she played through every possible way the night could go, none of them resulted in them surviving. She looked behind them to see, to her terror, to see several of the vampires sprinting after the car and not falling far behind.

"We're here!" as Willow turned around and Cordelia slammed her brakes in front of the library door. As soon as they stopped the girls were already out and rushing through the doors, closing them as soon as they had cleared the door. Mere moments later the vampires started to beat on the doors as the girls pressed back almost screaming in fright.

"What! What are you all doing?" Giles asked as he heard them rush in and yell in fright.

"Whadaya think?" Cordelia yelled back as one of the vampires broke the glass. In reaction she did the first thing that came to her mind, she bit it and yelled, "How do you like it?" Giles immediately noticing the urgency started to move furniture and blockade the door. Willow broke away and grabbed the first weapon she could find, a small sign, and started to beat the vampires back out the doors.

As soon as the door was suitably blockaded, they were able to breathe freely for a moment. Then Giles gasped, "The windows!" at this Willow and Jenny rushed to the back of the library to block the widows also. Then, Giles heard another noise and gasped again, "My office!" before rushing to block the last entrance to the library leaving Cordelia to keep holding the main door.

Jenny and Willow were holding the bookshelves to cover the windows. "These aren't going to keep them out for long!" Jenny yelled over the beating against the shelves. Willow heard this and felt that sense of hopelessness strengthen in her chest wishing her to be somewhere but where she was.

'No! I can't leave them, not when they need me suppressing the need to run away. "Come on we just need to keep them out till Buffy kills the Master right." Willow yelled back, trying to reassure herself more than anything.

The two girls did not notice the snaking tongue-like tentacle move towards them and lightly wrap around the first living thing it found, Willows ankle. Suddenly the vampires stopped attacking the windows; Cordelia looked through the window in the main door to see them running away. "Yeah! We must have scared 'em off or something. Then they heard Willow's scream. When Willow felt the tentacle wrap around her leg pull her to the ground and in the moment where she hit the floor something in her changed. The feeling in her chest grew and 'snapped', suddenly she could sense everyone around her: Giles, Jenny, and Cordelia, even Xander and Buffy! Then reality snapped back and in her fear her instincts took over and she disappeared to the one place she knew she'd be safe.

Buffy walked to the school with a sense of fatal determination, flanked by Xander and Angel. All of them were already ready to die, for some reason. Xander's feeling in his chest was growing, he could tell something was changing him; the feeling was quickly growing to its apex as they entered the school, the one vampire they found was knocked on its arse instantly by Buffy followed by a witty comment about bad guys.

They reached the stairwell that Buffy knew instinctually would lead to the Master. She stopped and addressed the two males following her, "You two stay here, keep the minions off of me and I'll deal with the Master. Got it?" they both nodded curtly. With that Buffy headed up the stairs to find the Master. The guys took positions on either side of the door to the stairwell. Then four vampires ran up to them from the direction of the library. The vampires though were obviously not looking for a fight decided that numbers rule and they could do with a meal.

The first punch was thrown by Angel that stunned the vampire in the brown shirt keeping him down for a while. Xander got hit in the face by a vampire in a blue shirt and staggered as he felt something change in him. The vampires started moving slower to his eye and then his tightening in his chest finally reached its end and 'snapped'. He recovered quicker than usual and then swung out missing the vampire's face by a few inches half- instinctually a tingling covering his forearm, "Arrrgh!" The vampire yelled as it reared back holding its face as blood came through his fingers. Xander was wondering what happened when he looked at his hand. "Huh?" he said staring at the ebony bone-like blade extending from the top of his wrist. He saw it flowing into his skin so he knew he wasn't stabbed with something. "Okay, fight now, wonder why this doesn't hurt later and fight now," He shrugged letting his limited fighting skills take over and swung the jagged blade in a low uppercut catching the vampire in the gut under the rib just the right position to pierce its heart. The vampire's eyes widened as he felt the blade extend through him they finally glazed over mere moments before it finally returned to dust. He swung horizontally with his bone blade thing to cut into the next nearest vampire, green shirt this time, the vampire tried to jump out of the way and but Xander was moving on par with the vampires now and caught it in the neck dusting it from near decapitation. Xander turned to see Angel take out the brown shirt with his stake. As the dust hit the ground Xander turned again as he looked for the last vampire, but the vampire was all ready halfway down the hall to the exit, running like hell was at its heels.

"Angel, you go after him I'll hold off any more that come by," Xander commanded.

"Okay, be careful," Angel replied somewhat cowed by how fast Xander has moved easily on par with himself, not to mention the blade extended from his wrist. Apparently Xander was practicing some sort of dark magic but it wasn't the time to confront him so Angel just followed his order. He turned and ran for the escaping vampire moving visibly faster, but still it would take some time for Angel to catch up.

"Okay, what now?" Xander asked, he looked at his blade and saw that it was growing out of his arm and was some sort of bone substance, a dark color like the color of dried blood with more black. Then Xander closed his eyes concentrating, picturing his hand without the blade, trying to will it gone he silently felt a cold wash over his hand and checked his hand, it was gone, a quick glance confirmed his feeling. Then Xander heard a noise that raised every heckle in his body, Willow's scream.

"AHHHH!" Willow screamed from the terror of the Hellmouth Beast wrapping its tentacle around her ankle. She was so terrified that she didn't even notice the lack of a tentacle wrapping her ankle or the fact she landed on tile not the carpet in the library.

"Willow!" Xander yelled as his best friend who suddenly appeared out of nowhere screaming. He rushed over to her, he looked at her and he could see white spiny plates covering her body in random places like a poor sort of natural armor. When he shook her and yelled her name again, she finally opened her eyes as stopped screaming to see her favorite Xander-shaped friend standing over her.

"Xander? " Willow asked, obviously confused about how she ended up here instead of a monster's stomach, "What are you doing here? Where are we?" she asked this time looking around to see her surroundings. She saw the staircases and realized they were in the school halls. She also noticed that she could still sense everyone around her. It was a weird feeling, then she asked, "Why is Buffy on the roof?"

"The school hall, how'd you get here, I heard you screaming and why are you covered in these plates?" Xander replied, trying to hope Willow didn't notice that he didn't answer her last question. No such luck for Xander.

"Plates! What plates? Where? " Willow said as looked at her body to see the white spiny bone-like plates covering her. "AAAAAAAH! ", she screamed again as she swatted at the plates, luckily they slid off of her body like water on oil; Willow was appeased when all of the plates were off of her. When the plates hit the ground they dissipated into air as a mist slowly but visibly as if that was all they were. After Willow's minor freak out was finished she turned to him and asked again, "Why is Buffy on the roof?" as she slid her resolve face on.

Knowing that he stood no chance, he took the simpler path and relented, "Um…fighting the Master…"

"What! '!" Willow shot off into her trademark Willowbabble.

"Willow! Breathe!" Xander shouted to stop his best friend from asphyxiating from talking too much without breathing. Willow stopped and then Xander started to explain what happened in the lair. Once he had relayed his story he added, "Willow, you didn't see Buffy, she changed somehow, there was no way to convince her to back down just to try and help her succeed. Now can you try to explain to me how you got here? "

"I don't know… Something grabbed my leg and pulled my down and I was wishing I could be anywhere but there and there was this feeling in my chest making me want to run away until it snapped and suddenly I wished to be where I'd be safe and I ended up here," then with a shiver she added, "Covered with those weird bone things."

"That's weird, and by Sunnydale standards too. 'Cause I had this feeling in my chest a kind of tightening that kept growing until I was attacked by some vampires and then that feeling snapped too! All of the sudden I could move as fast as the Brooder himself and then do this," Xander said as he held his hand out and willed the blade-thing to grow back out of his wrist, looking at it he noticed that it didn't pierce his skin but rather grew out of it. The blade looked like some sort of solid black bone blade with jagged edges.

"Wow..." was Willow's only response as she was instantly wordless. Then her head shot up, "Should we tell the others?" she asked, trusting Xander to know what they should do, even if Xander wasn't the best at school he was always the one to know the right thing to do.

"No, Angel saw me and he was wiggin' out from it, I think this is different from regular Sunnydale weirdness. If they don't say anything, we don't; if they do we'll spill all. Is that okay with you?" Xander asked. He didn't want anything to disrupt their friendship with the rest of the scoobies but he wasn't sure if they could handle this.

Willow nodded with acceptance and then her eyes widened in fear, "Oh no! I left Giles and they were fighting that monster! We've gotta go help them!" Willow gasped. She hopped up instantly Xander following her in step. They then started to run full speed to the library, the halls were clear of vampires and the run was short. They burst through the doors, without Cordelia holding the furniture in place the door opened easily to see Jenny on the ground being attacked by the Hellmouth Beast and Giles and Cordelia attacking the Beast's head, Giles with an ax and Cordelia with a broke off banister. Xander rushed for one of the heads of the monster, while Willow went to save Ms. Calender, who Giles was keeping the monster from eating but was unable to remove her from the danger. Xander got there first and struck the beast with a double-handed ax blow that miraculously sliced into the flesh and bone burrowing the blade into its cranium with inhuman strength eliciting a howl in pain.

Willow, however, went directly to save her favorite computer teacher and careful not to injure Jenny dragged her out of the Hellmouth Beast's grasp. The young redhead may not strong but she was able to drag her teacher to safety easily enough.

Then just as Willow cleared the beast with Ms. Calendar, two things happened: one, Xander laid a deathblow to the head ending with his fist through the skull up to his forearm that he was fighting (there were at least three heads, more the merrier) and two, the Master crashed through the roof only to fall on a banister that had broken itself during the fight with the Hellmouth Beast. The Master was impaled on the banister and sat for what seem be to be an eternity before he finally began to become dust half-laughing half-screaming the entire time until he finally succumbed to death.

The monster quickly slid back into the hole from which it had come, dragging along its recently deceased head. The hole in the library soon healed itself. 'It's kind of eerie to watch ground move and stretch like it is now,' Xander thought staring at the closing hole.

This of course was among the more mundane thoughts at this time. Giles was actually wondering how Willow had disappeared and also how Xander was able to punch through the monster's skull when an ax had trouble denting it. Of course the only plausible explanation for this was that Willow and Xander had used magic to augment themselves. 'That's perfectly reasonable but still incredibly dangerous without supervision and I should give them both a talking to about it.' Giles quickly decided.

Jenny, who had not noticed Willow's disappearance due to the monster attacking her and was simply thankful to be alive, was the first person to speak. "Willow, thank you and you too Rupert, I'd be dead without you, Thank you." She said as she hugged the petite red-head, her eyes red from nearly crying from hysteria.

"Hey…" The word came quietly but everyone heard it. The small blonde girl who had saved all of their lives was back, but different, Xander noticed. She seemed cowed now that her mortality was proven, the fire of defiance wasn't quite burning as brightly. "How'd we do?" Buffy asked tentatively.

Giles was the first one to speak, "Good, Good I believe, we all lived and no one was hurt or killed thankfully," he smiled of life's small blessings. "I believe celebration is in order now even, a little relaxation after our near apocalypse."

Buffy brightened slightly with that, "Yeah, I'd like that, a lot actually, a little fun after all this, I'm ready to party." As she said this Angel returned the wayward vampire apparently dead now, seeing him she brightened some more and said, "Come on guys, I hear there's a party tonight," With this Cordelia started to move and offered a ride to the others, Buffy and Angel agreed both tired too much to walk the way to the Bronze.

However, "Umm… I'm not really feeling up to partying right now, I'm just gonna head home." Willow said sighing slightly to emphasize her tiredness.

Then Xander said, "I'm about the same, you guys go and me and Wills will get home ourselves, okay" he shrugged and both Willow and he left quickly before anyone could stop them. They were outside the parking lot heading the opposite way from the Bronze to avoid Cordelia and Buffy trying to pick them up before they finally decided to slow enough to talk. Xander spoke first, "Okay Wills, you're the brains, do you have any idea what happened tonight, at all?"

Willow seemed a bit hesitant before she answered, "I do but you may not like it." Frowning as she said it.

"What? What could be so bad?"

Willow took a breath before she answered, "What do you know about mutants?"

Professor Xavier set down the helmet linked to the Cerebro cortex, sighing. He had just run his weekly check on Cerebro for any mutant pings. And just minutes before he was about to set the helmet down, two extremely powerful mutants showed using their powers, if momentarily, in southern California, Sunnydale, California to be exact. However, that was all he could tell, there was some sort of psychic interference that prevented Cerebro from discovering their names or any other details. He called Storm on the intercom, "Ororo could you please prep a flight for southern California, we have some prospective students to find."
