Welcome to my first crossover! I play both of these Nexon games and I always get made fun of for it. "Eww Maplestory! It's so 2D!" or "Eww Mabinogi it looks so boring!" Usually I find that the people that say this have never really tried the other game.

Well Demon Slayer is my favorite Character in Maplestory, so I thought it would be fun to see how he would survive in Erin! Considering he looks so much like an Incubus. Should be fun!

Chapter 1 - In a Strange World

It's been so long since I awoke and found myself inside a cave. I had somehow ended up in an egg which was being used as a power source by a strange machine. The ones stealing my energy call themselves the Black Wings. When I first awoke I used a large amount of my powers, which in my weakened state I no longer had control of.

I was rescued by a man known as J. He is a member of the Resistance that fights the control of the Black Wings. Along my journey I've learned that the Black Wings are actually working to revive that traitorous Black Mage. I hope I'm there to kill him when they do. I hope I am… but I'm still not sure if that will happen.

You see somehow I've been transported into a different world. The monsters are not the disgustingly cute things I fought in the Maple World. The people who would talk to me in this new world said that it is called Erin. Most people wouldn't talk to me though. They'd run screaming or try and attack me even though I say I'm fighting the Black Mage.

Odd… because that usually works. Instead in this new world they've never heard of him. The evil of this world is called Fomor. Many of the humans and elves here believed I was one of these Fomors. Something called an Incubus.

This is the world of Erin where I am trapped. This is the story of one girl, a Millitean, who was the bridge between Maple and Mabinogi.

…where am I…? The Demon Slayer cracked his eyes open and rolled himself onto his side. The cold stone floor felt good on his swollen cheek. Slowly he sat up and looked around. This was not the cave of the Horntail… He had just been there with some Adventurers… and then…. What had happened next? There was a bright light… then… long flowing white hair… a black dress… beyond that he couldn't remember anything.

He looked up at the chandelier on the ceiling. The bright lights were hard on his sensitive eyes but he delt with it and looked around. It was some kind of room. A celler or maybe a dungeon… it wasn't like the dungeon of Sleepywood that's for sure. It couldn't be. It wasn't overrun by those annoying Kargos.

The only thing in the room was a small chest. Chest are usually good right? Isn't that what that one annoying Hero with the cane had said? Getting up, the Demon Slayer walked over to the chest. He tapped the side of it with his mace, curious if it was full or not. It could be some sort of trap. He'd never seen anything like it just sitting around before.

He reached to open it and the accursed thing nearly bit off his hand. DS spread his wings and jumped back away from the box that had now grown teeth. "Vile monster…" He shot himself forward and smashed the box to the side with one swipe. It fell into the coner and laid there montionless.

"That was hardly worth my time." He looked around again. There were two doors. One was blocked by a large door with a keyhole on it. The other lead to another room with yet another chest. "Perhaps if I kill enough of these things I'll find a key."

This time when he opened the box it didn't try to bite him. It just opened like normal but as soon as it did five strange looking creatures popped up. Short creatures, they didn't look particularly bright. They also didn't look friendly as they turned to stare at the Demon Slayer.

"I'm looking for the way out of here."

The creatures just looked at him stupidly. One of them raised its weapon, a small club, and ran to attack. Demon Slayer was too fast for it. He simply dodged out of the way and let loose the power of a Demon's Cry knocking it and all the others to the ground. These things are as weak as a mushroom… he thought to himself.

Going over he examined the bodies of several until he found one that had the key which he relieved from its former owner. It was a large red key. Well that made sense with how big the lock was. The red was odd though, either way it clicked smoothly into place and the large door slid up and open, revealing a very large room; a pile of boulders lay scattered at its center.

This monster he was able to recognize. A Golem is a Golem is a Golem. Doesn't matter what size color or amount of moss growing off them. He entered the room and watched as piles of bones along the edges of the room were reanimated. Skeletons never did that before… He pulled out his weapon and faced the enemy. The door closed behind him.

"Curses… Trapped." There was a closed doorway across the room. I'll have to hope one of these has a key like before.

One skeleton ran towards him sword in hand. The Demon Slayer used his Demon Lash to easily knock the attacker aside. He felt a sharp pain as an arrow grazed his arm. He let a second shot ricochet off his shield and raced forward slamming into the Skeleton. It crumpled to the floor like the first. This is almost too easy. He was forced to amend that statement though when the golem slammed its arm into his side. Another arrow whooshed by while he was fighting off the golem.

Why are the mobs here so far away from each other? Jumping into the air DS summoned the spirits of Dark Metamophisis. They will keep the golem at a distance for now. He calmed himself to gather up enough power. Blinding Darkness was not the easiest of skills to control and it often failed to contain the targets. This time it was successful. The golem and the skeleton were frozen in place. Well actually the skeleton simply collapsed into a pile of dust as did the others but either way the attack worked.

He pushed back the golem with a multiple strikes from his Demon Lash. With the monster unable to move the battle was over quickly. As soon as the Golem slammed to the floor, the door at the end of the room opened. The Demon Slayer moved quickly to the next room. He needed to figure out where he was and fighting monsters in every room wasn't going to do that.

In the last room was a statue of a woman with wings. He might have thought she was also of the Demon race but her wings were more feathery. Perhaps she was one of those Adventurers that loved to accessorize. There was a chest in the corner of the room but he really didn't care to fight anything else. There were no other exits to the room.

"Ok well now what?" With no other option he smashed the chest with his mace. It broke open revealing a simple wood club, some sort of scroll, and some gold coins. Examining the coins He saw they looked nothing like Mesos. He couldn't even read the inscriptions on them. That was no reason to not keep them though.

This seemed to be the final room of the dungeon if there was a prize here. I can assume that was a boss monster in the last room. Considering how much stronger it was than the others. He still wasn't sure why a golem was considered a 'boss' though. Ready to admit defeat the Demon Slayer leaned back against the base of the statue. Suddenly he could feel his body being transported almost like with a return town scroll. He closed his eyes and let the power take him. When he next opened his eyes he found himself in yet another underground room.

This had the same statue, though slightly taller. The difference in this room though was there were other people in it. The young children got off the floor when they saw him.

"Oh my Godess! Is that an Incubus!"

"No way! What's that doing in Ciar?!"

"Should we fight it?"

"Are you kidding? I'm only level 50! I'm out of here!" The boy ran to the stairs and fled. The girl stayed where she was.

"Excuse me." The Demon Slayer said. "Can you tell me where I am?" Based on her clothing he felt it safe to assume she was an Adventurer, though with that grubby dress she must not be very strong. High level Adventurers were always vain about their looks.

She looked startled when he spoke to her and glanced to the door as if she was thinking of running also. "You're in Ciar dungeon… near Tir Chonail." She began to inch to the door.

"What is this Tir Chonail? Is that a town?" She nodded. "Can you show me the way?" Her eyes bulged open and she shook her head, turned and ran.

"Wait! I'm just… argh stupid noobs… Always over-react to everything." The Demon Slayer followed her up the stairs into the cool air of the evening.
