Klein shook his head and turned his attention back to Leafa. “Like I said, it's no problem.” Klein insisted. “I owe your brother a lot. We're comrades after all. Don't go acting like its some big inconvenience for me . . . Leafa. We will get her back.”
“I know.” The Sylph said quietly as she leaned against the stony surface.
A soft low hiss filled the clearing and both Klein and Leafa shot bolt upright. The boar seemed equally confused and began to look about in fright.
“What is this, what's going on?” Leafa already had her sword in her hands.
They felt it before they heard it. A faint shaking that turned to rumbling and then grinding like stone against stone. Immediately, both Faeries were back on guard. The ground began to tremble, pebbles dancing at their feet.
“What is that?” Klein asked to no one in particular.
“Definitely not more dogs. Is it . . . ” Leafa began
Suddenly, a jet of hot acrid air burst from the earthen wall that Leafa had been standing against, passing just between the two Faeries, and leaving hole as Large as a human head. Klein caught only a brief whiff. But whatever it was, it was pretty powerful. He felt his eyes watering at what could only be described as the overwhelming stench of rotting meat, carried on hot and humid breath . . . Breath?
The earth shuddered again, and Klein felt his heart stop as shards of rock began to crack and brake away. A trio of silver ovoids, each about a meter long, clustered tightly together in a triangular pattern, were revealed centered at just above head level on the earthen barrier. Then, in a single rippling motion, the mirrored surfaces withdrew revealing three ovoids of vivid green. The green orbs spun about smoothly, each containing a single, blood red, slitted pupil.
“Okay . . . That's bad!” Klein said as two years of SAO and twenty three years of common sense kicked in. “Leafa?”
The girl was frozen in place at his side. The ground shook again more violently. The whole earthen wall rippling. Dirt and stones falling away, grass and plants tearing loose. Slowly the eyes rose up, and up, and up. More earth and roots fell away. A milk white head revealed itself, rising up into the air, undeniably conical and reptilian, but something in the line of the jaw and mouth reminded Klein of pictures he had seen of wales. Hell, the thing almost looked cute. A series of questioning chirps rose from someplace deep within the creature's skull.
By now the boar had fled back into the forest in an attempt to take refuge.
“Leafa!” Klein gritted out.
The girl was shaking now, completely transfixed by the eyes. She'd handled herself well enough against the mobs last night, but this was something else entirely. The Whale-Snake headed monster began to open its mouth and all sense of cuteness vanished in an instant. Muscles trembled as jaw unhinged and unfolded, and the sleekly conical head was transformed into a nightmare of gaping maw and sword like teeth. The chirping cry from earlier was replaced by a vicious hiss.
The earthen wall was revealed for what it actually was, the body of an immense white serpent, rising from the earth and wrapping around most of the clearing. The serpent began to coil up, turning menacingly towards Leafa. Klein didn't even bother calling out to the girl this time. Like a spring coming unwound, the serpent lunged forward. Its mouth and sword teeth fit to swallow a grown man and turn him into sashimi in a single gulp. Klein slammed into Leafa, dropping his sword and sweeping the girl off of her feet before kicking off with all of his might. The serpent rocketed past beneath them, its long body flowing like water before circling back around, angered that it had just missed its meal.
“Kyuuii!” Sylphied cried as from on high Tabitha raised her staff and a hail of icicle projectiles materialized to rain down on the unsuspecting serpent below. Ice shards, sharp enough to shred flesh and hard and heavy enough to batter apart armor, fell like rain across the serpents hide. Tabitha might as well have been hitting it with spitballs. The serpent doubled back on itself and fought back. A short sharp jet of some clear viscous fluid shot from its mouth, narrowly missing the dragon. It would have been a pretty week boss if it was land bound and couldn't fight back.
“Get clear!” Klein shouted to Tabitha. “That thing's at least a field boss!” If this area had been a forest in ALfheim as well, it might be a formerly quest related dungeon boss. Considering that it had been laying dormant the latter seemed likely.
Klein and Sylphied rose back up until they were well out of the Serpent's range. The monster turned and lashed about for a while longer before its body described a figure eight and glided off into the forest, leaving only the upturned earth and thoroughly destroyed clearing to mark its passage. As they watched, the trees began to ripple and sway, describing a path off to North West.
Only as his breathing slowed and he took account of his senses did Klein realize that he was still holding Leafa in his arms. The girl's face was bone white and she trembled softly. There was a world of difference between fighting normal mobs and facing down something like that. Leafa was a tough kid, she was Kirito's sister after all, but Klein had seen plenty of strong players freeze up the first time they faced something like that. Especially when death was a real possibility.
“Hey, Leafa . . . Are you okay?”
The girl shook her head slowly. “I . . . I'll be fine.” He felt her shiver one last time as she got herself under control. A little bit of color returned to her cheeks. “Uhm, Thank you.” She said, and then, “You can put me down now.”
“What? Oh. Right!” Klein carefully released the Sylph as she materialized her wings and took to the skies beside him. Klein looked down and noticed his empty scabbard for the first time. Glancing about, far below he could see where he and Leafa had been standing. The Serpent had cut a deep trench through the earth, scraping the ground as it went. There was no sign of his Katana. “Damn! It ate my sword!”
“Sorry. That's my fault.” Leafa shook her head. “I promise I'll make it up to you!” She added quickly.
Well, he hadn't made a habit of blaming people for things that were his own fault, and he wasn't about to start now. “It's fine. You can chip in for a new one we get back to Arrun.” He offered. Damn, he'd really liked that sword.
“What was that?” Tabitha asked as they returned to Sylphied. The small mage looked off in the direction that the serpent had traveled.
“I have no clue.” Klein replied, “Leafa?”
“Mmm. I don't know much about boss monsters outside of the Sylph territory.” The Sylph apologized.
“The Dogs . . . Feeding it?” Tabitha asked.
The Dogs had herded the boar very carefully to this area before retreating. That meant they must have known the boss was lying dormant here. Were the Pixies taking care of the boss? Klein wondered. Damn, KoKo had told them lots about the Pixies but maybe he should have had her write it all down.
“I can hear more barking.” Leafa said suddenly.
“What? Which way?” Klein asked.
The Sylph placed her hands to her ears and closed her eyes in concentration. “It's . . . To the west. The dogs are definitely to the west.” In the distance, Klein saw one of the old growth trees shudder and snap like a twig, the Serpent ramming through anything it couldn't avoid. Sylphied turned to the west, overflying the serpent's path and allowing the Mage and Faeries to observe from the sky.
They only caught brief glimpses, Tabitha didn't dare to bring Sylphied too low. A flash of serpentine white, and out ahead, bolts of blue fur herding the boar from earlier back together. The dogs didn't try to stop the boar. The wild pigs would likely have simply charged through the Dagger Dogs if they tried to prevent their escape from the monster at their backs. But the pack type mobs weren't trying to stop them, and the serpent wouldn't have needed their help even if they had. The serpent descended upon the rear most boar like lightning. What Klein saw through the tree's was like watching the Shinkansen passing through the station. The squealing cries of boar gradually grew fewer and then vanished altogether.
The dagger dogs went silent, scattering off into the woods. Having already been fed the Serpent seemed uninterested in chasing after the remaining morsels. For a brief moment Klein saw something small, yellow and black, flying above the dogs. A Willow Wasp, and no doubt a Pixie rider. What could the Pixies be trying to do by waking up a boss and then leading it along with food? They were leading it. Leading it West . . . Away from something? Or towards . . .towards Tarbes! It suddenly occurred to Klein what was happening.
“They're luring it.” He muttered.
Tabitha glanced to him and Leafa perked up.
“What do you mean?” Leafa asked.
“Look, pixies have a taming ability, but it only works on small mobs and bosses are supposed to be pretty much impossible to tame on top of that. Maybe it can be done now, but it would be incredibly hard and dangerous, right?”
“Right.” Leafa agreed and then suddenly understood. “But they don't need to tame it. They just need it to go where they want it to go.” Leafa's face was set into a look of dawning horror. Up until now. The Pixies had possessed only their small mobs with which to attack Tarbes. But with something like that on the way, if they were successful in directing it towards Tarbes, they'd be able to wipe the village out.
“Leafa, are your wings good?” Klein snapped around. Stupid question, Sylphs were among the best fliers, and Leafa was one of the most skilled Sylphs.
“Un.” The Sylph nodded determinedly, understanding what he was about to ask her.
“We're going to track this thing for a while longer. You head back to Tarbes and warn everyone.” Why couldn't towns still be safe zones? Klein thought bitterly. Yeah, an invincible town wall to hide behind would be pretty sweet right now. “Tell KoKo what we saw and then tell the Village Chief to get everyone together. They need to get ready to evacuate.”
