We walked through the Antarctic, it was pretty windy and not the brightest, but the wind wasn't enough to really hamper me, so I could walk normally in the surprisingly clear land. The wind only picked up a bit of snow to throw at us, which wasn't an issue, given who was travelling. I kept my sense in the snow I was walking on so I could look out for sudden drops, that way I wouldn't fall down a crevasse.

Above was a dark sky that was covered in stars, each one a brilliant firefly against a black curtain, with the moon peering down like an eye. But not an eye with malicious intent, instead more like an eye belonging to a watchful parent.

I got the impression that Jack was frustrated that he couldn't just fly ahead, but I was grateful that he hung around.

Every now and again he'd jump into the sky so he could see what was ahead. After a while I heard him shout.

"Found it!"

"Really!?"

"Yeah, just keep walking forward there's a hole a few hundred metres ahead." He said as he floated down.

"That doesn't make it Pitch, there are people doing research out here."

"Might as well check it out."

As we walked along, we noticed a black shape become clearer and clearer, very noticeable in the white Antarctic landscape.

As we got closer Jack and I began to tense, seeing the sandy form of a black horse pacing back and forth.

"Nightmare." Hissed Jack , clutching his staff tightly.

"Nightmare?" I asked quietly, not wanting to alert the thing to our presence.

"They're bad dreams, with a form. I thought only Pitch could control them."

Despite the situation I had to hold back a snort of laughter. Nightmare? That sounded like a bad pun!

Recovering myself I said. "Well, if they're here, then Penelope was right."

"Or she's leading us into a trap." Said Jack darkly and I sent a glare his way. Why was I the only one willing to give Penelope a chance?

Jack levelled his staff at the Nightmare as we slowly made our way towards it. It seemed to be pacing in front of a dark patch in the snow and ice.

"Is that the hole you saw?" I whispered.

"Yeah, so we've got to get past that." Jack whispered in reply.

The Nightmare suddenly stopped in it pacing, it's head reared up as its ears flickered around. It turned its head in our direction and it lowered its head, nostrils flaring as it snorted.

I stood stock still as its golden eyes glared at us, there was something about it that made my feet root to the ground. Suddenly its pun of a name seemed very accurate; this is something you'd see in a nightmare.

"Jackie! Snap out of it!" I heard Jack cry as he fired a blast of ice from his staff.
Frost formed on my fingers and spread across my hands, quickly turning into ice.

The Nightmare reared, letting out a whinny and charged at me. My eyes widened in fear and
I held out my hands in a feeble attempt to stop it as I let out a scared squeak. The ice on my hands flung itself at the Nightmare, slicing into it and causing it to let out what could be considered a cry of pain.

Jack swung his staff in a downward arc, sending ice to pepper the side of the Nightmare.

Gaining courage I drew my hands up, gathering the surrounding snow and hardening it into ice. I flung my hands apart, shattering the ice into shards, then flung them forward at the Nightmare.

Black sand scattered the area like blood, but still it wouldn't go down.

Jack had flung himself into the air and was now flying down feet first, his staff out in front of him. It hit the Nightmare in the back and scythed through the sandy back of the creature. It let out one last whinny as it was cleaved in half, then collapsed into black sand, which was carried off by the wind.

Jack and I looked at each other with worried eyes, words not needed. If those whinnies had reached the base below us, we could be in trouble.

We kept walked and approached the hole. It was wide enough for several people to fit down, and there wasn't any operating equipment. This was where we needed to be.

It went into the earth rather than ice and seemed to go far down, to the point where I couldn't see the other end.

Jack and I looked at each other. "Let's go." We said at the same time.

Jack flew down the hole while I sent an ice bridge down and began skating, following the glow from Jack's staff in the near darkness.

At the bottom the tunnel seemed to curve so that it came out level to the floor of the cavern and as we reached the bottom Jack came to sudden halt. I skidded to a stop behind him sending ice all over him. He didn't seem to notice as he sat in the air, looking into the cavern.

I looked over his shoulder and felt a little ill.

There were around a hundred people of various ages tied up and in sand cages.
Most of them were hanging from the ceiling; I'm guessing they were the ones that could control earth and plants. Only a handful were in cages on the ground and from here I could see that one of them held Billy. My heart seemed to clench as I saw him there, looking so tired and defeated.

Most worrying were their jailers, there were roughly fifty of them milling around, a couple on the ground, guarding the grounded prisoners, but most were sitting on sand seats high above the ground. It wasn't silent, but there wasn't exactly much talking going on.

The ones on the ground seemed to be more wary then the ones above. I suddenly heard a bark of laughter from one of them, who continued talking none too quietly.

"Seriously? It probably just noticed a Leopard Seal or something. There's no way that one Descendant is going to try to take on all of us! How would they know that we were here anyway?"

Jack and I looked at each other, mirroring each other with the relief on our faces. They still weren't expecting us, we still had the advantage.

"And you're just going to take that risk?" chided another voice, female this time. "I don't care if it's nothing, I'm still going to have a look."

Jack and I looked at each in panic as a figure broke away from the main cavern and headed towards us. If she saw us here, it was game over.

Her red head bobbed over to us, her grey eyes focused entirely on the dark exit that we were currently hiding in.

Jack and I pressed ourselves against the wall as she passed us. She didn't appear to notice us as she prepared to head up to the surface. If she reached the surface then she'd know that something was wrong, but at this point my mind went blank, I had no idea what to do.

Jack, on the other hand, did something I didn't expect.

He lifted his staff upwards, moving silently over to the Descendant of Pitch. Before she knew he was there Jack brought his staff down quickly on her head. There was a crack and I winced as the solid wood made contact with her head.

She swayed slightly on her feet and started to fall over. Before she could hit the floor I darted forward to catch her, so we wouldn't make any unnecessary noise.

I lowered her to the floor and sent Jack a disbelieving look. Why did he feel the need to do that?

To his credit he did look a little ashamed, but looked back at me with steel in his eyes.
He didn't like it, but felt that it had been necessary.

I narrowed my eyes to show that I didn't agree, but I was willing to let it drop, we had other matters at hand.

I turned my gaze back the cavern, pushing my glasses firmly up my nose as I tried to think of a way to proceed.

The surrounding cavern was a hodge podge of black rocks, which seemed to be a trend with their bases. There were holes in the walls which I imagined led off to other parts of the base, and I hoped that there wasn't anyone we needed to free down them.

I looked back over at Jack, who motioned that he went left and that I went right. I nodded and we set off.

I kept the bridge of ice going, melting it behind me as I circled in and up. We managed to get above the cages without them noticing us by sticking to deepest shadows. Looking across the room I could see Jack holding up his fingers.

He had three, then two, I braced myself as another came down. When he wasn't holding up anymore fingers we flew across the cavern, touching the sand holding the cages to the ceiling.

The ice made the sand become brittle and the weight made it snap, sending it to the floor, with occupant hopefully unharmed. The ice also spread inside to the occupant, making the bonds break as well.

As cages fell to the ground the alarm went up and people saw us, and the yelling and blasts of sand began. We went down to just above the cavern floor once we were done, dodging blasts of black sand.

I'm pretty sure I heard someone yell, "I told you so, you idiot!"

We zig zagged our way through the cages, covering them in ice and causing the bars to break. As we went the Descendants of Bunnymund became free and fought back, I yelled at them over the sudden din.

"Head to the Tunnels!"

One the earthmovers opened a hole in the ground and they dived into it. Jack hovered by the edge of it, keeping the Descendants of Pitch back as I continued to free people.

Finally they were all out and I headed to the hole, although the Descendants of Pitch didn't want to make it easy for me.

My ice blades came back into action and I slashed away their attacks as I skated just above them, enough to brush their heads with my ice skates.

A wall of black sand appeared in front of me and spread lengthways to block me. I tensed my legs and jumped as I got close enough to it, using my power to give me a boost. I soared over the wall and landed on the newly formed ice bridge and continued skating towards the hole.

I angled the bridge downwards and went into the hole without losing speed, someone was waiting below me and as I passed them the hole closed, plunging the Tunnel into darkness.

I couldn't see a thing, so I let the ice run in front of me and tell me what was in front of me. I felt a small gust of wind as someone bounded past me, probably the same person who closed the hole.

Gradually light began to trickle in and after a while I could see where I was going. I reined back the ice so I could just skate on it, no longer needing it to help guide me.

An opening appeared ahead of me and I shot through it into an underground cavern, but this was different to the black rock of the Descendants of Pitch's cavern, this place was covered in lush green grass and smooth rocks. Flowers were dotted all over the place and there were giant egg shaped rocks with legs scattered around.

I continued the ice bridge until I could finally put on the brakes, skidding to a halt in midair and sending flakes of ice all over the place.

Below me a hundred Descendants of Bunnymund cheered and I felt my face flush with embarrassment, feeling very conspicuous up in the air.

"Jackie!"

I looked through the crowd to see Billy forcing his way through the crowd to me. From here I could see that he was clearly tired, but that didn't seem to diminish the enormous grin on his face.

"Billy!"

I melted the skates and jumped into the crowd, which parted for me. I run up to him and before I could say anything he pulled me into a rib crushing hug.

"I...can't ...breathe..." I gasped.

Billy released me, then grasped my shoulders and looked me up and down, ignoring my flinch of pain.

"Well aren't you a sight for sore eyes!" He then pulled me back into a hug, but he was a
little gentler.

He let me out and asked, "So how did you escape?"

"Well, I never actually got caught."

"How!?" He and few others cried. "You were right in the thick of things!" Cried someone from the crowd.

"Surprisingly, Penelope came through for me."

"What! That no good..." Started Billy.

"Stop, if it wasn't for her you'd still be in there, so be grateful."

"You know." Said Jack as he floated down, "I had my doubts, but her information was accurate, and they weren't expecting us, so I think she's being honest about this."

Billy's eyes went wide when he saw Jack, along with everyone nearby, as one they stepped back respectfully as he landed.

"M-Mr. Frost..."

"Wow, Bunny was right. You really don't have to call me that."

"Sorry Mr- I mean Jack."

We were interrupted as a rumble echoed throughout the place. Jack and I looked around worriedly, while the Descendants of Bunnymund didn't react.

Another opening appeared right to where the other one had already closed and out of it flew someone else sliding on ice, but they seemed to sliding down it like they were on a sled.

They shot out into the crowd and they scattered as another six people shot out behind them.

A few more figures appeared, two were floating in the air, one was clinging to one of the flyers and the final one was Bunnymund.

"Hey there Bunny!" called Jack as he flew over to join him.

I made my way through the crowd and walked over to where the others landed, easily guessing who they were.
