(Rayquaza: Rayquaza, Guardian of the O-Zone Layer, Xeno and DarkSide's ally, owner of A.N.K. Tower [A Mystery Dungeon, non-legendary Pokemon From Uber and OU tier live there], sent invitations to our heroes to party at the top of A.N.K. Tower)

Part 1 takes place in Xeno's PoV (Point of View)

A.N.K. Tower
1F

As we enter the tower, I begin talking to DarkSide about the interior of the Tower while we head towards the lobby area. The invitation said to wait in the lobby until further notice.

"Look at this architecture. Must have taken him weeks to make this place,"

"I think it's just that because he's a legendary, he can have non-legendaries build it for him."

Still seems a bit bland, though. Maybe Rayquaza should've hired some interior decorators to furnish the place. A painting here, a statue there, and a bit of coloring other than white would have made this place look so much better.

I just wonder why he would build it in the Mystery Dungeon Universe? His was just fine, I know because it's ours too! Then again, not a lot of Pokemon actually reside there and maybe he wanted to have only Pokemon?

That thought was soon answered when our heroes went into the lobby itself. The place was filled with expedition teams, some fighting each other, some chatting. Then, Rayquaza appeared, or at least a Double Team clone of Rayquaza.

"Greetings my guests! Before I explain the rules, does anyone have any questions?"
"Why is it called A.N.K. Tower?"

"A.N.K. stands for A Night in Karazhan!"

After that was said, our heroes quickly changed into their alternate outfits to match the mood.

"This tower is actually a Mystery Dungeon, but with rules! The rules are very simple: those who get to the top can party with me and all the other legendaries and mythicals. You are not allowed to fly or climb on the outside to get to the top of the tower, you have to go through the inside. If everyone on your team gets their HP lowered to 0 and have no methods of reviving, the staff will take you and your teammates to the hospital outside, healing you to full health and restoring all your power points. You then have to start from the beginning of the tower. If you have spare cash, you can go to the Kecleon Shop™ and buy some items from him. He has infinite of every consumable in stock, so you can buy as much as you want! I paid him to make sure he doesn't set up in the tower, so you have to stock up outside the tower. However, he will be on the roof, serving luxurious meals as well as selling is wares and buying yours. Once this speech is over, I will teleport you all to the second floor, where you will then have to find stairs up. If you want to try again after being defeated, there will be teleporters in the lobby taking you to the second floor. Each team will get their own parts of the tower to go up, but all teams will eventually be forced to interact with other teams. Roughhousing is allowed when parts of the tower merge and if you have psychic powers, so feel free to attack other teams as you please. With that said, I hope you enjoy your time in A.N.K. Tower!"

A beam of light appeared under everyone, and we were all transported away.

Blinded by the liiiiight, revved up like the deeeeeuce, another runner in the niiiiight, blinded by the liiiiight!

Wait, if he was going to put teleport pads in here after we all started, why didn't he just put teleport pads in the room to begin with? Probably has something to do with giving everyone an equal start and single file lines wouldn't be really fair, but in that case make the whole floor teleport pads! Better yet, how will he even get the teleport pads in here in the first place?! Ah, whatever, less thinking more focusing on the task at hand.

A.N.K. Tower
2F

I started to laying down anesthesia (instant KO gas) traps while DarkSide is laying down nuke traps (upgraded explosion traps). Of course, we teleported them randomly around the opposition's part of the Mystery Dungeon. We decided to discuss some…intriguing decisions Rayquaza made while we went through some hordes of Starmies and Tangrowths.
"Why exactly did Rayquaza not put us at the towers top? He knows we can handle everything he throws at us, so why not just give us VIP access to the top? I mean, we count as legendaries too, right?"

"Maybe he is using this place as a test, to see how well he made it. It would explain why he even allowed wild Pokemon in here. What I think is strange is that the invitation didn't even tell us about the whole Mystery Dungeon part."

Well, as long as no beauty curses are inflicted onto me, I'm fine. ( journal/Escaping-To-My-Light-630370022 will explain the beauty curse.) Oh, the readers don't know why I don't like the curse itself, well let me explain. One of my past adventures, that may or may not be written down later, got me infected with Yalini's curse. Normally it only affects female heirs to a throne, but Lunaala, controller of curses, adjusted it for DarkSide and myself to make it trigger when we use an attack. There is no way I would ever not attempt to first solve a problem with violence, so I was really miserable as my body started thinking I was a woman and made me a gentle flower. There is no reason in the world as to why I wouldn't hate it.

If he is using it as a test, why invite us? Surely he would get much better data with the other guests. There is no point in him inviting us unless this is a prank against us or something. Hey, is that the stairs?

A.N.K. Tower
3F

"Judging by the Radiance Orb, this floor has a huge amount of hallways, looping with each other. Wait, is that a golden apple?"

It was indeed a golden apple, a rare item that is known for being the best and rarest delicacy in the Mystery Dungeon universe. We never had these before in our lives, mostly because we never need to eat, but that doesn't mean we can't enjoy eating food. However, after picking it up, almost every empty space (if not all of them) on this floor became occupied by Chanceys, each with their own Eviolite. It was at this moment that we knew this would be "one of those days".
I used my blades to create a current in order to push myself and DarkSide into the air close to the ceiling. DarkSide proceeds to use Ammo Roulette, and lands on a magma bomb, causing a magma bomb to be fired into the center of the floor, coating the ground of the entire floor in liquid hot magma. Since we were so high up, they couldn't get hit by any of the Chancey's attacks (guess you could say they didn't stand a Chance-y), so we proceeded to go up the stairs with the sounds of Soft-boiled being used over and over as well as the tranquil sounds of the bubbling magma filling our eardrums.

Music to my ears! Not as good as some other music I hear, but it's good for the atmosphere.

I would feel bad for them, but they kind of deserved it, luring us with luxury food. Maybe if they knew we were broke, they wouldn't have ambushed us. What's that, you readers didn't know we were broke either? Well long story short, just because we are the Guardians of all Dimensions doesn't mean we get payed. We are so broke, we live in a cardboard box. Sure, there may be an entire portable underground base bellow the box, but it's not the same as a secret base behind a bookshelf or in a tree.

A.N.K. Tower
4F

Upon entering the room, it seemed to only be one giant room, no hallways, no Pokemon, and the stairs to the next floor were on the other side of the room. It seemed easy at first, but after taking just one step, a wall trap activated, turning the room into the world's most complicated maze.

"Remember to keep going left, Xeno."

"I know how these work, DarkSide."

Finally, the heroes got to the stairs, but before they went up them, one of Rayquaza's Double Team clones appeared in front of them.

"Oh, it's you two. I didn't realize you were actually here."

"But I'm the one who asked what A.N.K. stood for!"

"Oh, you were, weren't you? My bad, there were so many Pokemon in the crowd I couldn't distinguish one from another."

"We are the only ones wearing clothes!"

"Ah, so you are, no matter. Anyway, it seems you two are slacking behind, everyone else is already at floor 9. So just for you guys, I will warp you to floor 10. You won't miss out on must, just some more fighting and looking for stairs…I think. I was just created today so I wouldn't know if there were any special touches on floors 5-9. Anyway, just touch this warp twister and you will be sent far away in a flash. After that, you just have to scale the other 89 floors until you get to the roof. Good luck guys, you will need it."
The clone proceeded to swirl around, creating a twister. Myself and DarkSide jumped in, and were teleported due to spinning so fast.

So will this just make a hole into floor ten or- whoooooaaaah?!

Why tornado? Sure there is a better- waaaaaaaaay!

"Well that was something. But if Rayquaza's clones could do that, why didn't he just have them teleport us to the roof?"

"Beats me, but look who's in front of us. It's the 'Mons in Black."

Indeed, it was the 'Mons in Black.
(Zekrom and Darkrai copying the Men in Black, same clothes, same tools, and a theme song with the same tune but with different lyrics [still in development], they still use their powers, coming to a theater near you.)

"What are you guys doing here?"

"'Quaza told us to be the first of the ten trials. It's a shame he labeled us as the easiest, but at least we were allowed to customize the floor before this one. How was it, by the way? Rayquaza would love to hear about it." Zekrom said, but we had to break the bad news.

"Actually, we never did floor 9. Rayquaza realized we were here, and since we were behind everyone else he let us skip here."

"Really dude? REALLY?! We put so much effort into our ingenious design. It was a stealth segment with Zekrom's minions and my nightmares and you ignored all of it! Now then, any questions before you begin your first trial?" Darkrai said, displeased

"I do, are you everyone's first trial or is it just us?"

"We are everyone's. If you must know, Darkrai and I put barriers around the stairs until we are defeated in the room the stairs are in. That way they have to fight us. But enough talk, have at you!"

As the battle starts, I use Elemental Roulette. My swords glow to show me I got Fighting and Ice, and I proceed to combo Zekrom into oblivion. DarkSide proceeds to go into the Shadow World, and beat up Darkrai's shadow, causing him to take damage as well. I notice DarkSide is having a bit of trouble, so I throw the Fighting element blade in a tornado-like way, causing a flurry of fists to attack Darkrai while I concentrate on Zekrom. Eventually, they both fall down, and we do an all-out attack, finishing them off.

"What a fight, I can clearly see why you were the next Guardians of all Dimensions."

"We shall release the barrier, go on through the stairs and face the 89 other challenges, then you can make it to the roof and party like you just saved everything!"

The barrier around the stairs disappear, and DarkSide and I go on through.

Those guys must have been training, they usually take less time to defeat. Maybe they really can start a business with a bunch of 'Mons in Black at their side.

One has to wonder why they came in costume. It's not like they used their special tools, they just did what they normally do. Maybe they heard it was a party and mistook it for a costume party? Then again, it's not like we have any room to complain about costumes when we are dressed as priests.

END OF CHAPTER!
Xeno and DarkSide have overcome the vicious 'Mons in Black without letting them even get a hit off! However, our heroes are only a tenth of the way there. What other trials has Rayquaza set up for our crew and the rest of the guests? How will the other 89 floors progress? And isn't it strange that there are ten trials, yet the story constantly tells about the 89 floors?
TUNE IN NEXT TIME TO FIND OUT!
