I do not own Doctor Who or Once Upon a Time. Only this story. I hope you enjoy :)
Chapter 1: Aurora
"Remember when we went to Neverland?" The tenth Doctor asked Rose Tyler as she walked into the TARDIS console room.
"Yes." Rose replied. "It was terrible. It turns out Peter Pan is evil and a Dalek almost destroyed us."
"It got me thinking." The Doctor said. "If Neverland and Peter Pan are real, then what other people and worlds are real as well?"
"I take it that means we'll be going to one of them today." Rose said. "What if it ends up being totally different than what we thought?"
"Then it's more fun." The Doctor replied.
Rose gave him a smile. "So where are we going?"
"A land called the Enchanted Forest." The Doctor said. "Most of the fairy tales we know and love seem to live there."
"Are we looking for a specific one?" Rose asked.
"No." The Doctor said. "It's going to be random."
The Doctor then flipped a switch on the console. Then, the TARDIS made its unique wheezing sound, signifying that it had landed somewhere.
"Where are we?" Rose asked.
Suddenly, they heard a feminine scream coming from outside. The Doctor did not wait to answer Rose's question. He raced past her and opened the door. He found that the TARDIS had landed in a fancy bedroom near the bed. By the door, a woman in a purple dress and brown hair stood in shock. She had clearly made the scream, most likely because she saw the TARDIS materialize in her bedroom and it frightened her.
"Hello." The Doctor said.
"Who are you?" The woman asked authoritatively.
"I'm the Doctor." He replied. "Sorry. I didn't mean to barge into your room like this. It was honestly an accident. I shouldn't have had the settings on random."
Then, Rose exited the TARDIS.
"Hello." She said. "I'm Rose Tyler."
"What are you two doing here?" The woman asked. "Are you magical?"
"No." The Doctor said. "It's all science. We travel in this box from place to place and we've accidentally ended up here. That's all. We don't mean any trouble."
"What's your name?" Rose asked the woman.
"You do not know me?" She asked. "You must be from far away. I am Aurora."
"Shut up." Rose said in shock. "As in Princess Aurora?"
"Yes." She replied.
"As in Prince Phillip and Maleficent?" Rose continued to ask.
"Don't mention that name." Aurora said. "Maleficent has done no good to my family. She recently put me in a sleeping curse. If not for Phillip, I'd probably still be asleep."
"He woke you up with true love's kiss?" Rose asked.
"Yes." Aurora replied.
"That's so beautiful." Rose said.
Suddenly, they all heard an explosion coming from the base of the castle. The three of them rushed to the window of the bedroom, which was at the castle's highest point, and looked down. They saw a giant dragon breathing fire and breaking down the castle gates. Then, the large animal was consumed by magic smoke and took the form of a woman in a black dress, holding a magic staff, and wearing black dragon horns on her head.
"It's Maleficent." Aurora said. "She must be looking for revenge. Again."
They saw Maleficent walk right through the now destroyed front door and right into the castle.
"She'll be here any second." The Doctor said.
Suddenly, the lightbulb on top of the TARDIS started to flicker and it started to make its signature wheezing sound.
"Doctor!" Rose yelled. "What's happening?"
"It's a program that I'm playing with." The Doctor said. "I reprogrammed the TARDIS to disappear when it senses danger. I wanted to make sure it didn't end up in the wrong hands."
"Well it's going to leave us here!" Rose shouted.
"Everybody inside!" The Doctor yelled as he ran to the TARDIS, opened the door as it started to fade and ran inside.
Aurora followed the Doctor and made it into the TARDIS. However, as Rose tried to get inside, the door slammed shut and within a few seconds, the TARDIS disappeared, leaving Rose trapped in the Enchanted Forest.
"Who are you?" Maleficent asked as she entered the bedroom. "Where is Aurora?"
"She's gone." Rose said. "You'll never find her."
"I don't play around." Maleficent said. "Tell me where she is. Now."
"I don't know." Rose said. "All I know is that she's gone."
"The Doctor took her didn't he?" Maleficent asked.
"What?" Rose asked.
"The Doctor." Maleficent said. "I'm not deaf. I heard the TARDIS. I just didn't think he'd ever come back here."
Rose was surprised. The Doctor had told her that he'd never been to the Enchanted Forest before.
"What did he do before?" Rose asked.
"He and his companion got tangled up in my plans with the Evil Queen and Snow White." Maleficent said.
"What companion?" Rose asked.
"Her name was Donna." Maleficent said.
Rose had never heard the Doctor mention that name before. She figured Donna must be another woman from the Doctor's past like Sarah Jane Smith.
"Well they're not here and I don't know where they are." Rose said.
"What's your name?" Maleficent asked.
"Rose Tyler." She said.
"Well Rose Tyler," Maleficent said, "you clearly care for the Doctor. That means he clearly cares about you. If he cares about you he'll come back. And when he comes back he'll bring Aurora with him."
Maleficent then waved her arm, consuming herself and Rose in magic smoke and disappearing.
3 hours later...
Prince Phillip sat at a table in a pub with Robin Hood, a renowned thief.
"She's gone." Phillip said. "I was on a hunting trip. When I returned to the castle. The guards told me that Maleficent attacked and that now Aurora is missing. I've heard you broke into the Forbidden Fortress before. I'm requesting your help to do it again. I'll pay you any amount of money. I just need to get my love back."
"Good sir Prince." Robin Hood said. "In the name of love, I will do it for free. I'll gather my men. We should be ready to leave in about an hour."
"Thank you." Phillip said.
"As I said, I do not require your thanks." Robin said.
Robin then exited the pub to assemble his merry men. Prince Phillip walked outside and looked at the blue sky.
"Aurora." He whispered. "I'm coming for you."
Phillip did not know that Aurora was not at the Forbidden Fortress. Instead, she was in the TARDIS with the Doctor, hurdling towards an alien world.
