A gold coin dropped from the entrance of the door, located on the ceiling, and Spike's mouth dropped to the floor, he was drooling at the sight, and his heart almost stopped from the pure excitement that overcame his body.  The door opened ever so slowly, and more coins, a few gems, and a diamond spilled out.  He kept looking in awe, and as the last crank of the rope tugged down on the door, it swung open, and crashed against the floor, falling off it's hinges.  A huge glowing light, sprayed all across his body, and he started to cry in joy at what he saw.  It was beautiful and Spike fell to his knees and prayed.  He prayed for making it, for completing his journey.  He held his hands, and spoke softly, through his tears,

"Praise Celestia, and Praise Equestria, thank you for this fortune,"

Lying on the floor, in a huge spread, reaching from the center of the room, and all the way to Spike's feet, was a huge, massive, enormous pile of gold, diamonds, and coins.  It reached the ceiling as the pile rose high up in the air, and Spike got back up from his knees, and climbed the top of the loaded room, and dived down into the diamonds.  He swam through them, all jingling in his ears.  There were much more treasures than just money, there were golden shield, diamond swords, silver armor, and crowns.  Everything a king would need, and Spike had it all to himself.  Out of his greediness, he compensated on sharing his load with the Mane 6, after all they were his best, and possibly his only friends.  He dug himself out of the shining stash of riches, and lay down on top of it, grabbing the biggest, most tasteful blue gem, and bit into it.  It was above holy of all tastes, and he enjoyed every millisecond of this divine cuisine.

After ten or so more gems, he felt an extreme vibration, that shook his while body.  He was snapped out of his ecstasy like state, wiped the drool from his mouth, and lifted the map out of his pouch.  The map was lighting up, almost as bright as the treasure, causing Spike too look away for a moment until his eyes adjusted.  

His claws gripped the map tighter to force the vibration down, and he squinted his eyes as words began to carve into it.  It was a more 'insidious' hand writting, clawed down, instead of written...

It read: Pain, there is pain.  We warned you, and now, you must face the consequences of your actions, you greedy abomination.

"Who in Equestria are you calling greedy?" he yelled, hypocritically, and the map started to tear itself up.  The rips started at the bottom and sides of the map, and brought itself to the middle of the paper.  After it was split into four squares, they dropped from Spike's claws, and fell onto the gold, then set themselves afire, simultaneously.  The ashes were whisked away by one more blow of wind, and that was the last of the wind, he would feel.  The torches that were lighting the room, turned blue.  The whole scene changed in a matter of minutes (or three paragraphs) and there was a blistering silence.  Spike began to feel the fear rising up in his spines.

He talked to himself, "Okay, Spike, calm down, you got you're gold, now get what you can, and get out,"  He looked for an exit, but as he remembered, no exit was found, and the door he entered in was now sealed.  He was trapped, all he had was the opening in the ceiling, leading to the top of the mountain, or what seemed to be the top...

He was about to grab a handful of gold and diamonds, when he pulled something out of the enormous pile.  A diamond sword, and it was thick too.  It gleamed in the moon light, and he held it up for inspection.  It was never used, no dents, and it would cut through paper in no time flat.  This was way beyond 20% cooler than you're average sword.  It had a design on the base of it, had a cross like grip, and pointed edge, sharpened to perfection.  He was stunned at it, he had never seen a sword so beautiful in all his life, and he was completely distracted from the gold.  He was taking this, and all the gold with him, but it would take a ton of trips.  He put the sword in his other hand, his right one, and started trying to shovel some of the loot in his pouch.  He was almost full, when a strange noise raised down from the farthest side of the dome like room.  The blue fire twisted from each torch and then, they all were blown out by an unseen force.  "What is t-t-that?" he thought.

From the side of the room, a small opening in the shape of a small hole slid open from the wall, and a small light glowed through it.  That was now the only light source besides the moon, and the light started to get wider and wider, like something was being pushed through the hole.  Then, Spike watched in terror, and a long, string like worm slid out of the hole, but it had rock and red all over it.  It was moving towards him, slithering out, like a snake.  Spike didn't completely know what it was, but he was for sure, that when it got a few feet closer to him, it was made of pure lava.

"Oh, horsefeathers," he sighed, but he knew lava wouldn't hurt him, so he tried to ignore it.  It was extremely slow, Spike looked away for only a few seconds, as he emptied out his pouch, and prepared himself, when the light of the snake lava disappeared. Spike looked around, and the hole in the wall had shut, and nothing was in the room with him.  Did he imagine it?  No, it was there, so he hopped off of the treasure, and walked over to the wall, where the hole once was,

"What was that?" he said, out loud, and then a few words carved into the wall in front of his face,

"A distraction," it read,

"Uh oh," he thought, and then the floor around him sank.  

The circle like floor started to sink, but the center with the treasure stayed at normal elevation, and he dashed off towards it.  When he reached it, the floor had sunk about ten feet, and then, spouts sprung out from the bottom, and the floor became to fill with water, and it reached two inches under the elevation of the treasure, almost splashing his feet.  He dunk his claw in it, and he sprung up.  It was freezing cold, a dragon's worst enemy.

He grabbed the sword, and he exclaimed to the empty room, "Show yourself!", and a voice came from nowhere,

"I am, I am here, I am everywhere,"

"What the hay is this,"

"I am everything, every element,"

"Who are you?"

"Some call me a monster, some call me a beast, but honestly, I have no name," it churred,

"So, physically present yourself!"

"I cannot, only by my will shall I, not yours,"

"Then let's finish this, I know you are here to stop me from taking the treasure,"

"Not from you just taking the treasure, but from you leaving here alive,"

Cue the Long, Infamous Epic Fight Scene

Spike went hot, his blood boiled, he traveled all this way, and he was leaving with it.  He yelled at the invisible being to come get him, he was ready for a fight, and he gripped the sword between his hands.

"As you wish," and another gust of fast wind whipped through the air, smashing Spike in the face.  He flew back, and smashed into the treasure, pushing some of it into the water.  He didn't notice it, and he got back up, his face swelling up,

"Is that all you got?"

"Far from it,"

Another few gusts of wind blew, and hit Spike's leg, bending it backwards, and tripping him over.  He held onto the sword, as he was punched hard in the stomach with two unseen fists, and he bent over and coughed, sucking in air.  He knelt down, and tried to catch his breath.  How could he fight something he couldn't see, he had to make up something.  He tried to reach for something useful in the treasure stash, but it was only met with more kicks and punches, across his face, on his back, and in his chest.  He was picked up by the force, and tossed farther into the pile of gold and other treasures.  His purple blood dripped down from his snout, and stained a few coins.  He tried to get his body to pump adrenaline in his body, but nothing was working right, his body felt like his insides were mashed up, and they probably were.

That didn't matter, the longer he stayed there, the more kicks he would receive in the stomach and the more blood he would cough up, coming from his chipped tooth.  Every time he tried top stand up, another punch was imprinted on his face.  But then, he realized what to do, and he aimed his body towards the pile of treasure, and when another hard kick came into his chest, he was sent flying into the treasure.  He tried to search for something useful, like a magic vile or an enchanted weapon of some sort.  He could here that something else was in the pile with him, it was following him, as he crawled through the stash.  He did find a few bottles in there, but most of them were wine, and not magic of any kind.  He tried reading the label, but after the second bottle, his foot was pulled on, and he was thrown from the treasure pile.  He slipped over to the edge of the floor, and was leaning over the water.  He saw the treasure shake, and an invisible figure erupted from it.  It was tall, and slender.  It looked like a very strange creature, but he could only see the shape from how the gold coins slid off the body.

He could only see one plan that would actually work.  It would put everything at jeopardy, but it was the only way.  In the water, the air pockets would show up on the invisible creatures mouth and skin, so with a deep breath, he grabbed the sword, and pushed himself into the water.  The beast followed him.

The water was freezing, and it pierced Spike's skin, but he had a task to complete, and tried to ignore the pain as much as he could.  He searched around, and spotted the creature, the bubbles were moving from it's mouth, but there was a large amount coming from it, so Spike concluded that it could breath water. "Great, just great,"  He took the sword, and found that the slicing motion was easy to move in the water.  He swung just next to the sir bubbles, and slashed into something meaty.  There was a green color coming from an area around the pockets of air, and he expected it to be the creature's blood coming from it's possible shoulder.  There was a loud screech, and Spike could hear it, even through the density of the could water.  That was enough of the water, and he pulled himself out, while the creature was grabbing its wound.

He pulled himself out, and blew fire into his hands, and rubbed his scaly body and warmed himself up.  He was feeling a bit better, and then he heard another splash, but the body of the monster was actually visible, from the blood oozing all over it.  The figure was not much bigger than him, but it was in the shape of a free form style.  The body was slowly moving around, and it was shaping itself.  The wound was healing up in the spot, but not fast, or very healthily.  If he wanted to beat the beast, it would have to be quick, fast, and used with all of the strength he had.  This was the challenge he had to face, so he buckled down his moral, felt the adrenaline pump and his heart beat faster, and he charged toward it, swinging the sword wildly.  He lunged the sword deep with the monsters stomach, and blood spewed all over the floor.  The pool formed around his feet, but not on him, just missing him, the pool spilled into the water, keeping the mess away from the treasure.

Spike's feelings started to enlighten, but then dropped as he was pushed away from the sword.  The beast's legs were now visible, but they were just long lines, and they were shaking two, and changing shapes.  It was beast with the power to change shape?  Who ever designed this was clever, clever indeed...  Spike got up from the ground, and backed away slowly, he watched as the monster slowly pulled the sword out of it's stomach, and the blood stopped pouring.  The sword was thrown at him like a spear, just missing his foot, and he tried to yank it out of the ground.  He pulled the sword from he ground, but it chipped away from the top.  It was now a flat top sword, but it was still useful for slashing.

A punch was landed right in Spike's face, as he was unaware of how fast it was, and he looked back up from his daze as the next fist came flying towards him.  With his reflexes, he dodged the punch, and brought the sword down on the arm of the beast.  It seared through the meaty skin and almost cut through it completely.  The arm seemed to only be holding on by a few strands of meat and flesh, and was wildly bleeding.  The monster payed no attention, and it brought it's almost amputated arm down on Spike's face, resulting in a slap, rather than a punch.  He had to drain it of blood, not try to chop it up, because it would just regenerate itself.  The arm attached itself back to it's hinges, and the monster was back in action.

Spike had his plan, and he wiped the blood from his face, and got in a fighting stance, and waited for the next few blows.  The new arm flew at him with lightening speed, hitting him in his chest plate, but didn't throw him off balance, it only pushed him back a few feet, with skid marks on the dusty ground.  He had a terrible thought, and he knew that if he was going to destroy this beast, it wouldn't not let him take the treasure.  He shrilled at the thought, all this way for nothing?  What would it be, Death... or Fortune?  He tried to suppress his thought, and he looked up, only to be struck again.  He didn't know if he was winning the fight, or losing it.  He had to be extra fast, and he was only giving a fair performance.

After the next punch was sent, he dodged it, like last time, brought the sword up, and hacked away, actually amputating the arm.  He could tell from the splat he heard, and the blood that was leaking out on the floor, in one spot.  More screeches, and Spike took the opportunity to  slash at the creature again, in the stomach, like he did before, but when he brought the sword to the stomach, he slashed to the left, taking out a big chunk of it.  More green blood spewed out.  The beast had A LOT of blood, but he could tell he was gaining the upper hand, but he couldn't taste victory just yet...
