(AN: I don't own Pokemon, just some OCs and the plot enjoy!)

Seeleena awoke first that morning, which was slightly unusual. But not extremely out of the ordinary. Sometimes her sister just liked to sleep in. She got up, to stretch her legs. She saw a note under Nightmare's paw that said she was going out for a walk, and not to be worried. That made sense. She must have gone out for a walk during the night, and come back tired, which was why she was sleeping in.

She continued to walk around quietly for a while, while she waited for Nightmare to wake up. Gee, Nightmare sure is sleeping in a little late. She must have been out late last night. Seeleena thought. But just as she thought this, Nightmare began to quiver in her sleep. She was shaking. Seeleena knew it wasn't from being cold. It was a warm day. So why was she… She must be having a Nightmare! Oh no… what can I do… Seeleena worried. Seeleena knew that she could use her abilities, her dream walking ability. Unlike some Pokemon, who could send others into dreams, Seeleena had an ability she and Nightmare called Dream Walking. She could walk in the dreams of other Pokemon with ease. She and Nightmare had discovered this when she was younger… But should she use it now? There was no question.

Seeleena laid down next to Nightmare, and closed her eyes, focusing on the dreams of her sister. Within an instant, she was in a cave, where Nightmare was being pinned down by a Raichu, and hundreds of Pokemon were fighting. Seeleena's eyes widened in fear, but, she knew what she had to do. She leaped forward, and rammed the Raichu off of Nightmare, and into a wall. Nightmare looked up.

"Seeleena? But how did you get here? And why?" Nightmare asked, looking confused.

"It's just a nightmare. You were shaking, so I dream walked in here, because I was worried." Seeleena responded. "Although, we should probably fight to get out of here, since I'm not sure what else to do." she continued. Nightmare nodded.

"I think you may be right… but… I can't let you be here." Nightmare said. "I don't want you to get hurt!" Nightmare said. Secretly, she was afraid of shattering Seeleena's innocence by having her witness this battle.

"No! I will fight along with you! I need to try and fight!" Seeleena growled back. Nightmare didn't have time to argue, as she shifted into a Sylveon, and grabbed the Raichu who was charging back at her. Nightmare did what she had done the night before, and threw him away from her, and, just like before, he was thrown into a wall, and she became a Flareon. Seeleena stared in amazement. "Night, is that your special power?"

"Yes." Nightmare said grimly, as she blasted the Raichu with Flamethrower. "I discovered that last night, while I was out." Nightmare dashed forward, using a Shadow Claw, followed by a Dark Pulse that finished the Raichu off, impaling him, just like before. But Seeleena didn't see, because she was watching the battling Pokemon in awe. Seeleena wasn't paying attention as Nightmare tackled her, and they rolled to the cave entrance, and suddenly, were both awake in their cave, gasping for breath.

"What… what happened?" Seeleena asked.

"We… we made it out." Nightmare said. "I… I suppose I should tell you something. Last night… when I went out for a walk… I saw that Raichu walking off somewhere. He looked a little suspicious, so I thought he might be a criminal, so I followed him. He was in this cave, making some speech about getting revenge for something, then all the Pokemon started fighting. I was trying to leave, but then he caught me, and pinned me down, right about where you came in. Then… well, our fight was the same in the dream. I was struggling to get free, when I suddenly changed, I then figured out how to shift in between my forms, and managed to beat him. I… fled before I found out what else was going on." Nightmare said, hanging her head.

"I see… that's why you tackled me out of the cave, isn't it? You knew you could flee, and you didn't want to stick around." Seeleena said. Nightmare nodded in confirmation. "Well… thank you Night. I'm sorry that happened to you. But you're okay now.

"Yeah… But we may need to move. That Raichu and his friends might come back, and I don't want to try and face them again. We should probably move out." Nightmare said, knowing full well this was a lie, but it fit her story, and allowed her to move closer to where Singularity and Brock might be. Or, at the very least, a change of scenery. Luckily for Nightmare, Seeleena nodded in agreement, and smiled.

"I agree." Seeleena said. "I'm sad to leave… but you know what's best." Seeleena sighed, and together, the two sisters began to pack up the belongings that they had, and left the cave where they had resided for quite a while.

(TIME SKIP)

Nightmare and Seeleena had packed up their things, and were ready to go. They left the cave, and began walking down the path, away from where they had come from to get here, and off into the unknown world. It was a warm day, but not too much. There was just a slight breeze, as they walked down the path, all alone.

The day progressed, and they continued walking, only on occasion talking to each other, mostly silent. But, as the day was nearing its end, Nightmare and Seeleena saw a town nearby, and, a short walk away, a cave where they could live. They began to unpack.

"So, what do you think of our new cave?" Nightmare asked.

"I like it! I want to go into the town tomorrow, to explore!" Seeleena said, excitedly.

"That's a good idea…" Nightmare said. "In fact…" she suddenly trailed off.

"Umm… Night? Are you okay?" Seeleena asked. Her question was answered in an instant, as Nightmare keeled over, and collapsed onto the floor. Seeleena jumped forward. "Oh no! I have to get Night to someone to heal her! But… what about her symbol…" Then Seeleena remembered the Sneak Scarf that they had. Seeleena dug through one of her bags, and brought out a pair of Sneak Scarves. She knew that they had used them once, to escape from a group of criminals that had come into the cave that they were in. Somehow, they could just blend in when they wanted to. So, Seeleena tied one around her neck, and one around Nightmare's covering her symbol. With this done, Seeleena, did her best to pick up Nightmare. She was much bigger than Seeleena, and heavy too, but Seeleena needed to do this. She began moving as fast as she could toward the town.

As she ran, she panted under Nightmare's weight. Nightmare was still heavy, but Seeleena couldn't give up now. She ran into the village, crying for help.

"Someone, please, help me! My sister collapsed, and I don't know what to do!" Seeleena cried, hoping someone would listen. A nearby Chansey turned around.

"What? Come with me then. My mother and I can help your sister, if she's hurt." the Chansey said.

"Oh, please do." Seeleena begged. The Chansey nodded.

"Let me carry her, she looks much too heavy for you to carry." she said. Seeleena nodded, as the Chansey picked up Nightmare's unconscious body, and they ran off in the direction of a house. As they burst in, a Blissey turned around.

"Oh dear, what is the matter?" she asked.

"Mom! This little Pokemon said her sister got hurt, and she came looking for help!" the Chansey answered her.

"Well, lay her down here, on the nest, and I'll take a look at her." the Blissey told them. So the Chansey did so, and the Blissey began to examine Nightmare. "What is your name, dear?" she asked.

"I'm Seeleena. My sister's name is… Night." she responded. The Blissey nodded, and continued examining her for several minutes.

"Well… it seems that your sister is suffering from severe shock mostly, and some internal injuries. The injuries I can fix in an instant. But the shock, that I can't do anything about." the Blissey said. "Do you have any idea what the shock might be from?"

"Yeah… she went out for a walk last night, and followed some Pokemon she thought looked suspicious, a Raichu. She thought he might be a criminal for her to catch. But she got caught, and had to fight him. I think that was her first real battle, and there were a bunch of Pokemon fighting, and that must have really shaken her up." Seeleena said. The Blissey scowled.

"If I know the Raichu you're talking about, it's a miracle that your sister escaped with her life. There has been rumours you know, about a dangerous Raichu, who is even trying to restart Team Oblivion." she said.

"Team Oblivion?" Seeleena tilted her head, confused. "What's Team Oblivion?"

"They… they were an extremely dangerous group of criminals, who hurt and killed, and terrorized the Pokemon world. They were stopped recently. They all died, killed because they refused to just give up." the Chansey answered. "I hear the worst part was the symbol that they left behind to mark their work. Pokemon are still afraid of it." she said.

"What symbol is that?" Seeleena asked, afraid of the answer. The Chansey then took out a piece of paper, and began to draw on it. She showed it to Seeleena. It was the symbol on Nightmare's chest.

"Apparently, they marked all their members with it too, and even had the member's children marked, so that they would be members for life." the Chansey said.

"W-who were the leaders who decided all this?" Seeleena asked, trembling now.

"A pair of Eevees, said to have the ability to walk in dreams, and not just that, also to transform into any eeveelution ever." the Chansey answered. She didn't seem to notice Seeleena trembling in fear. Or, at least she didn't until Seeleena passed out onto the floor.

"Now look what you've done!" the Blissey said. "You scared that child! Now we've got two patients on our hands!" But she came and picked up Seeleena, and laid her next to her sister. They both had healing that they needed.

(TIME SKIP)

Nightmare opened her eyes, her senses slowly returning. She had no idea where she was. The last thing she remembered was talking to Seeleena, before having a strange feeling come over her, and then… nothing. She looked around, seeing Seeleena curled up next to her, wearing a scarf. Nightmare then noticed that she was wearing a scarf, one that covered her symbol, and that she was in a house.

A Blissey came walking over. "Oh, good to see you're awake dear. You've been out for a couple days. Your sister came into town, carrying you, saying you collapsed. After what your sister told us, about being captured and fleeing that dastardly Raichu, it's no wonder that you were in shock."

"Y-yeah… it was my first real battle. And I think he tried to k-kill me." Nightmare said.

"Despicable." the Blissey growled. "I'm just glad a child like you escaped. Anyways, you're lucky. That Raichu was the one who was apparently trying to restart Team Oblivion!"

"T-Team Oblivion?" Nightmare asked, fear in her eyes.

"Now don't go passing out, like your sister. She's been out almost as long as you have!" The Blissey said, shaking her head.

"Why?" Nightmare asked.

"My daughter told her all about Team Oblivion. The symbol, the leaders, their powers and downfall. It shocked her so much, she passed out. They must have hurt you and your sister at some point, didn't they?" The Blissey asked.

"Yes. We had to flee our home because of them. We lost our parents too. We've been traveling since." Nightmare said. Again, it wasn't a lie, all those things were true. Just… It wasn't quite the full truth either. "We mainly just take care of each other, and try and get stronger. Someday we'll be a great exploration team!" Nightmare said, happily.

"Oh, I'm sure you will dear. I'm sorry to hear about your parents though. But… You seem to be doing fairly well for yourselves. Do you have a sort of guardian? An adult who watches over you?" The Blissey asked. Nightmare nodded. "Well that's good. Anyways, feel free to stay here until your sister wakes up. I do hope that it's soon."

The Blissey got her wish. Perhaps an hour after Nightmare had woken up, Seeleena did too. She yawned and stretched.

"Night? Is that you?" She asked, as she got up. Nightmare nodded.

"I'm so glad you're awake!" She rushed over to her sister, nuzzling her on the cheek.

"Thanks, Night. I was worried about you too, you know. You did sort of collapse in the middle of talking." Seeleena said.

"I heard you collapsed yourself." Nightmare said. Seeleena nodded. "Don't worry, we can talk later." Nightmare then turned to the Blissey. "Thank you so much for taking care of us." Nightmare said graciously.

"It was no trouble. I love taking care of others. Now, I suppose you two should let the two of you go back to your home. But feel free to visit me any time!" She said, smiling.

The two sisters smiled in response, and left the house. As they walked back through the village, Nightmare spoke.

"Thank you, Seeleena. You may have saved my life. And it was good thinking, using our special scarves to disguise my symbol." Nightmare said.

"You're welcome. But… Speaking of your symbol-" Seeleena began.

"Let's wait until we're back at the cave." Nightmare cut across her sister. So the sisters finished their journey in silence, until they entered their cave, where they found everything just as they left it a few days ago. Nightmare sat down, and so did Seeleena. Nightmare sighed before she spoke.

"So, you found out about Team Oblivion, didn't you? About their special symbol, that also resides on their chest? The horrible things they did? Their powers? Did you guess the truth?" Nightmare asked.

"If you mean, did I guess that we are the children of some of the most dangerous criminals ever to live, then yes." Seeleena responded, water in her eyes. "But why don't I have a symbol? Why didn't you tell me?" She demanded from her sister.

"To answer your questions, you don't have a symbol because I didn't give you one. When our parents left on the raid that they died at, they told me to name you Deceit of you were male, and Sabotage of you were a female. They also told me to brand you. They also said that they may not come back, and to flee if they didn't within 10 days, or seven days from your hatching. But when you hatched, and I looked into your eyes, I couldn't do what they had asked. So I gave you the name Seeleena, and didn't brand you. And of course, we fled when they hadn't returned. To tell the truth, I didn't know the truth until about a month ago. That's what was in the packet, besides the fighting techniques. The history of the symbol, and that's when I learned everything. I just wanted to shelter you." Nightmare said, beginning to cry herself. "But no one needs to know. With these scarves, we can become an exploration team. We can work to fix all the harm our parents did to the world." Nightmare said. "Our abilities will help us, but I truly believe we can do this."

"I… I hope so too." Seeleena said. She ran over to Nightmare, cuddling up next to her. You're big and strong, and can fight. I can do things too. We'll be the best!" Seeleena said.

"We will, we sure will." Nightmare said, smiling.
