Author's Note: Since a few people have asked about this let me clear it up. This story is not a crossover with anything else. The setting is original. Those of you familiar with my fanfiction know most of my stories are AUs of one sort or another. I figured since the premise of Overlord is a player and a number of NPCs getting sent to a real world, it was a perfect set up to send them to my own unique setting.

The skeletons that were automatically spawned by Nazarick were the weakest combat forces Ainz had at his disposal. They were standard level one skeletons with five hit points, an attack power of one, an armor rating of zero, and a movement rate of slow. Most of them were equipped with either a rusty sword or a wooden club. There were currently over thirteen thousand of them available. They were simply battle fodder. Back in Yggdrasil they were stationed outside the main entrance of the tomb and programmed to attack any strangers on sight. They weren't meant to provide any kind of real defense. Their role was just to delay an attacking party for a few minutes and allow any available Ainz Ooal Gown members to get ready. Any floor guardian, area guardian, or Pleiades maid could annihilate them in a few minutes. So his decision to use just five hundred of them in the initial attack force had surprised his subordinates.

Within the cavernous throne room Ainz had assembled the floor guardians and combat maids. Albedo was in her black plate armor and had her battle axe in hand. Shalltear was in Valkyrie form. Cocytus was armed with a magical weapon in each hand. The maids were in combat dress and ready for immediate deployment.

In addition, each floor guardian was permitted to select fifty soldiers who were also packed into the throne room. Golems, trolls, devils, vampire brides, wights and other strong monsters were ready and eager to kill in Ainz's name. They were here form show more than actual need.

"Ainz-sama," Demiurge asked. "Is it truly wise to use such weak troops? You are not even using the Veteran or Master Guards."

The Veteran Guards and Master Guards were each units of three thousand more powerful skeletons, and all of them equipped with magical arms and armor. They were meant to aid Shalltear in defending the upper levels. They were also fodder, but were slightly more valuable than the Common Guards.

"I agree," Albedo said. "Not only are they weak but to use them in such small numbers… even such pathetic creatures as the humans might have some hope against them. To even permit the possibility of defeat is unthinkable!"

"No such possibility exists Albedo," Ainz assured her and all the others listening. "I do not expect the skeletons to win. They are merely disposable pieces we will use to draw out all the enemy forces and allow us to see how dangerous they truly are. Even allowing that the humans are stronger than expected, there is more than enough power here to deal with them."

Demiurge grinned and nodded approvingly. "Ah, so this is merely one more experiment?"

"That's right. Defeat is not possible. The actual outcome was decided the moment I chose to conquer this city. So the only real question is how to defeat them with the smallest cost and collateral damage."

"Brilliant," Albedo sighed. "As one would expect of Ainz-sama."

"A beautiful strategy by our supreme leader," Shalltear declared.

"Now we will watch the opening of the battle. Gate." A gateway opened. Two abreast the skeletons shambled forward and crossed over. The line churned ahead, since there was only room for two it would take a little time to get all five hundred there. "Now keep in mind, I want as many living subjects as possible and to capture this place as intact as I can. Corpses can obviously be useful and a certain amount of destruction is unavoidable. Any humans who are fighting can be killed, but the civilians and any who surrender are to be spared. Is that clear?"

While he didn't name names he made a point to look directly at Demiurge and Shalltear. All his followers nodded their acknowledgement of his orders. Ainz waved a hand causing the Mirror of Remote View to expand. It gave him and everyone else a clear view of the events.

It began with the screams of a couple fishermen as the first skeletons arrived. The men sensibly ran away. The skeletons raised their swords and gave a slow chase as more and more arrived right behind them. The skeletons had no intelligence and could only be given basic commands. In this case they has been ordered to 'kill the living.' Being undead they could sense life energy. As more and more of them made it through the gate some began to split off in different directions toward other people on the docks.

All the fishermen and workers started to scream and to run. People came out of their market stalls and shops to find out what was happening. When they saw the skeletons they reacted the same, yelling out in horror and running away as fast as they could. It was amazing how a few undead could turn a routine morning into a scene of mass panic. While this was going on there were three pairs of soldiers roaming the docks. They were drawn by the initial screams. Four of them took out their rifles and just started blazing away. The effects of their gunfire were negligible. One skeleton had its skull shattered and collapsed. One was hit in the spine and cut in two, its upper half continued to crawl forward. A few others had ribs shot away or an arm, but they continued unaffected.

Ainz nodded silently. Rifle bullets were considered piercing weapons in game terms and undead only took half damage from such weapons. The third pair of soldiers hung back and watched what was happening. One of them finally began to move forward to help the others, but then his partner yelled something and turned around to run away. Seeing this the other one thought better of fighting and also ran from the scene. As more and more skeletons continued to arrive the four who had opened fire also decided to run. Ainz saw one of them viciously club a woman who was in the way. None of them were trying to form some sort of line or direct the panicked civilians or help them. They just wanted to get as far away as they could from the skeletons. People who were too slow to get out of their way were thrown aside.

"Pathetic," Albedo declared. "These humans can't even put up a fight against lowly skeletons. Goblins would do better. Are they worth enslaving?"

"It's even worse than that," Cocytus declared. "They have no warrior spirit."

"Yes, they are worthless." Albedo declared. "Weak and pathetic creatures."

"That is not what I meant." Cocytus breathed out a cloud of frost. "Even the weak can be brave and possess a sense of honor. A warrior should be ready to risk his life to protect his people. There is no shame in retreating before a greater force in order to continue to fight. But these men are not retreating, they are simply running away. They are not trying to protect the people, they are only seeking to save their own lives. They are cowards, and a disgrace to warriors everywhere." Cocytus turned to the throne. "Such men are not worthy of serving you, Ainz-sama."

"Even cowards can be useful," Ainz noted. "Of course these men are worthless to me as soldiers. It would never even occur to me to use them in such a role. Their corpses would be more useful as raw material. But I have a purpose in mind for them."

Because the skeletons' movement rate was so slow and because all the shouting and gunfire gave people advanced warning, there were no immediate deaths. The very first death didn't occur until the skeletons were more than a couple blocks from the water. Some were a sail shop when an old woman came out the door almost right in front of two skeletons. Ainz couldn't imagine how she had not fled sooner given the commotion. He assumed she had to be deaf. You could very clearly see her walk outside, turn, and THEN notice there were two skeletons in front of her. There was a look of shock and confusion before a pair of swords came down and cut her in half.

The sudden, brutal death bothered Ainz. The feeling was almost immediately suppressed, but it was still a waste. Human suffering and death no longer bothered him, but that wasn't the same as him wanting to cause it. The truth was Ainz saw himself in the role of Oda Nobunga, the man who had set out to end the Warring States Era of Japan. As had been the case with his homeland, this entire world was suffering because individual warlords were putting their own wants and needs ahead of their people's. He had no doubt that this world would be much better off under his direct control. Once he had the authority (and the reward crystals) he had plans to completely remake this realm. But the path to that better world was a bloody one, and he understood from the moment he made his choice that would be the case. He had to accept the fact innocent people would die to achieve his vision.

His followers were somewhat less troubled.

"Oh dear," Shalltear said. "Was she expecting a kiss?"

Almost everyone laughed. Ainz noted the way Albedo shook inside her armor. He pretended to laugh as well.

Three city blocks from the waterfront and the buildings changed from shops and store into tenements and apartment buildings. The size of the crowd running away grew noticeably. Most of the skeletons formed a single mass, deliberately following after them down Main Street. Small numbers went down the side streets or started smashing in the doors of some of the buildings. They were no doubt being drawn by the life force of people running away or by those who had chosen to barricade themselves in their homes. The army base and castle were located seven blocks from the water.

Since the first gunshots had rung out the men there had, had well over ten minutes of warning that something was happening. A number of soldiers had come spilling out of their barracks. A few had exited their gate and actually gone to see for themselves what was going on. Others went to the gate and asked the people fleeing. Most of them just stood about their compound conversing. More men came out of the barracks. Some went back in. Some hurried up to others to ask their opinion. Some formed small groups and waited by the gate. Some went up to the warehouses. A couple ran across the street to the castle.

"They are completely disorganized," Demiurge noted. "They have no plan of action in case of an attack."

Cocytus nodded. "They have no discipline or clear leadership. Truly, these men are worthless as warriors."

Eventually on of the soldiers who had originally been at the docks ran in through the gate. He started yelling. The mirror did not permit them to actually hear what was being said, but it was obvious. Some of the men there yelled back at him and gestured with their hands to the street.

"They don't believe him," Demiurge said.

"They will shortly." Ainz promised.

It was only a few minutes before some of the men who were standing in front of the gate began yelling to their comrades. Many more ran over to the gate. There they were able to see clearly a wall of undead making their way slowly up the street. There were more shouts. Men waved for the others to come join them. Some ran over, some jogged, a number remained where they were talking to one another, and some were only now coming out of their barracks. Several ran to the truck and cars.

A few dozen of the soldiers outside the gate shouldered their weapons and started blazing away at the skeletons that were still about a block and a half away. There were many desperate people still running out ahead of the skeletons. The soldiers cut them down without any hesitation. Those not killed outright were left bleeding in the street until the skeletons caught up and hacked them to pieces. The sudden sound of so much concentrated gunfire seemed to finally get the full attention of the men.

Everyone with a rifle ran to the gate. The vehicles were driven out as well. The men spread out across the street and formed an uneven line. Groups knotted together to form clumps of soldiers next to two or three men spread out. Everyone was shooting at full auto, just pointing their rifles at the mass of skeletons and sending as much lead towards them as possible. The truck and cars stopped behind the soldiers. The men handling the machine guns opened up, adding their fire to the mix. No one appeared to be aiming at a specific target. No single person looked to be in charge.

The sheer volume of bullets had an effect. Dozens of skeletons were destroyed as their skulls were hit or as enough of their bones were shattered to inflict five hit points worth of damage. But hundreds kept coming forward in a relentless march. As the horde closed to within half a block it was clear to see them begin to panic. Many were backing up as they fumbled to reload. Several simply turned around and ran. You could see their line literally beginning to waver.

It was at this moment their leader arrived on the scene with a dozen armed soldiers. Bloody Billy took out a pistol and shot down one of the deserters as he tried to run away. When the men noticed his presence they appeared to give a cheer. Turner handed a pair of keys to two of the soldiers who'd left the castle with him. Both ran as fast as they could into the army base. Bloody Billy climbed up onto the flat bed of the truck and yelled something at his troops. Whether it was encouragement or threats Ainz couldn't tell, but it had the desired effect. The men settled down and began to concentrate their fire. Ainz noted that the group that had come with their leader were spread out behind their line and were not shooting themselves. They had their rifles at the ready, but waited.

The soldiers kept shooting. The effect remained the same, some skeletons were destroyed but the rest drew closer. When the skeletons were only about twenty yards away things finally became interesting. The large doors of the two base warehouses slid open and the trump cards at last made their appearance on the battlefield.

"They have iron golems!" Albedo exclaimed with interest.

"Not golems," Ainz corrected. "Mecha."

Tobi had serviced the machines and described them in detail. Even so this was Ainz's first chance to actually see them. It was oddly exciting and disappointing all at the same time. To begin with, these really were mecha; war machines in humanoid form. This was something that had not existed on Earth, and a part of Satoru Suzuki remembered being a twelve year old in love with manga and anime. There was just something undeniably 'cool' about seeing genuine mecha on the move and about to fight.

On the other hand, these machines were definitely not Gundams or EVAs. They weren't meant to look impressive and colorful, they were designed to kill. They were a more advanced version of tanks. The mecha were about fifteen feet high. They consisted of grey metal abdomen, head and arms. Instead of legs, both machines were attached to twenty foot wide disks that hovered a couple feet above the ground. There were no hands attached at the end of the arms. Instead, each was capped off by a muzzle. Tobi had also informed him these mecha couldn't fly. Ainz knew it was silly to measure a piece of real world military hardware against the imaginings of a manga artist… but he still wished they looked a little more like Gundams.

The truck was parked in front of the gate. The mecha didn't bother trying to squeeze past. Instead they flattened the wire fence that surrounded the base got onto the street. Both mecha lifted their arms. The left arms were equipped with Vulcan cannons that could fire hundreds of rounds per minute. The right arms could fire one hundred and sixteen millimeter shells. They began to fire. A steady stream of grey smoke rose from the left arms along with a river of empty cartridges. From the right came bright flashes and puffs ad empty shell cases were ejected from the top of the forearms.

The shells exploded in the midst of the undead, sending up chunks of broken bones, asphalt and dirt. Huge holes were dug out of the street. Meanwhile the front lines of skeletons disintegrated, there was really no other way to describe it. They simply went from walking undead to piles of splintered bone in the blink of an eye. The two mecha were in action for less than a minute and each lobbed on three artillery shells before they ceased fire.

When they stopped all the skeletons that had been in front of them were left in pieces. Not even one was still intact. The street had been ripped apart and one bring building had fallen in on itself. The fragment of skeletons that had split off earlier would still have to be hunted down, but the main danger was over. So far as the humans could see.

Bloody Billy pumped a fist it the air and shouted something. His men responded with cheers and hugs and some of them shooting their weapons into the air.

"My, don't they look happy?" Shalltear said mockingly.

"The fools are actually celebrating as though they've won," Albedo said.

"So far as they know they have," Cocytus said. "They have no understanding of their true situation."

"Those iron golems, they are called 'mecha,' Ainz-sama?" Demiurge asked.

"Yes."

"They were effective, at least. The humans would have lost without them."

"They were decent I suppose, but nothing truly special. Which only shows how weak they truly are," Albedo sneered. "That so many of them could do so little is simply embarrassing."

"I hope they at least taste good." Shalltear said. "Otherwise they really are worth nothing."

"Well then, this has been informative, but I think it is time to bring it to an end." Ainz said.

Every face looked at him expectantly. They all wanted the chance to fight and earn his praise.

"Albedo and Shalltear, go. Remember, I want prisoners, especially their leader."

"I will bring him to you personally, my beloved Ainz-sama!" Albedo declared excitedly. She was hugging herself.

"Watch me closely, Ainz-sama! I will crush them in your name!" Shalltear swore.

"Crush only the ones who fight back, let them live if they surrender."

"Hai!" Both said before they rushed through the gateway.

Bloody Billy Turner listened to the cheers of his men. This was the best day of his whole damn life except for the day he'd killed his predecessor and taken over. He had no idea what those monsters were, maybe they had come out of the dead zones. He would have to ask the stupid Techs about them later. For right now he was happy to stand there and listen to the men cheer his name. He'd let them shout just a little more before he'd have to get them to work. They'd need to go through the city and make sure they'd got rid of all these monsters. Then he'd have to track down any deserters who'd run away. Any man who was more afraid of monsters than of him needed a bullet in the head.

He was about to motion for quiet when he looked up and gasped. His men noticed and they looked up as well. The cheers died away, replaced by stunned silence and a few curses. Floating in the air above them were two armored figures, one in black and one in red. The black one had a helmet with horns, the other had a pale girl's face with demonic red eyes, like something out of the sacred texts.

The black clad figure spoke in a woman's voice. "Rejoice, lower life forms! You have the honor to be enslaved by the most powerful and wise being in all creation. Out of his great benevolence he gives you the chance to surrender and become his property! Toss away your worthless weapons and fall upon your knees."

"But if you'd rather die," the one in red armor said. "That's fine too."

"By sky and sea," Turner whispered. Maybe these really were demons and this was the Long Night? He looked around. "What are you assholes waiting for?! Shoot them!"

The men moved to obey. Rifles and machine guns rose. More importantly, the mecha lifted their arms to fire. Bullets were just beginning to fire when both vanished in a flash. There was a deafening sound of metal tearing apart. Before his disbelieving eyes he saw one of his precious mecha split apart, right down the middle. The two halves fell open like a piece of fruit. He got a clear look into the cockpit, Alvin was still sitting at the controls. He was cut perfectly in half too, his guts and intestines were spilling out along with blood and other pieces. Standing at the bottom of it was the black armored demon. The second mecha had a hole ripped right through the middle. The red demon had gone out the back and had Wally spitted on the end of a lance like some poor damn fish. He clearly saw Wally move his hands a little before the demon laughed and threw him away.

"Die it is!" The red demon flew straight into his men. She laughed off their bullets cut them down like they were blades of grass. He saw blood gush out and form into a ball above the demon's head.

The black demon cut one of the battle cars in two, slicing the head off the driver and gunner, the bullets were bouncing off of her. The dead had risen and now two demons were killing his men.

"The Long Night has come. The Long Night has come." He whispered in horror. He jumped down from the truck and ran. If this was the end of the fucking world he wanted to live just a little bit more. He had no thought in his head beyond simple survival.

He hadn't gotten more than twenty feet when something grabbed him by the throat and lifted him up into the sky. To his sickening horror he was staring into the helmet of the black demon.

"You are Ainz-sama's prize, I will bring you to him." The happiness in the voice chilled his soul.

He tried to scream but couldn't. There was nothing for him to do as he was taken to Hell.
