This story take place near the beginning of the second season of OUAT when Emma and Snow are in the Enchanted Forest, but I may make some mistakes in when exactly events occur in that fandom. And some I may be switching around purposely to fit this story. There's one big glaring change you'll see fairly early on. Narnia is after the series ends. For those who did not finish the series (SPOILER!), everyone but Susan dies and goes to Aslan's Country.

And of course I own neither OUAT or Narnia.

"I need help," Regina said as she stormed into Mr. Gold's shop.

"I would say so," he said, taking in her unusually disheveled appearance. She gave him a rather sour look.

"My son escaped on me the moment he got back. He is determined to not live with me," she said, her fingers curling into a fist.

"And why are you coming to me?" Rumpelstiltskin questioned. "I already gave you the spell book. Surely you now have the magic to make him stay."

"I need something that will make my son want to come back to me. Holding on to him so hard, it won't make him love me. I need him to want to be with me," Regina said, rummaging through some of the various dark items in the shop. "I let him go for now, but I need him back. He's with his grandfather right now."

"So a spell to make him go to you willingly?" Rumpelstiltskin questioned, knowing there was no such thing.

"Yes. And I don't want a spell that makes him come willingly but makes him not him anymore," Regina said, still desperately looking through the items for anything that might work.

"You know as well as I that there's nothing for that," he said, still watching her. He could tell this was the desperate act of a desperate woman.

"What's this?" Regina suddenly asked curiously, picking up a decorated horn.

"It's a horn, dearie," Rumpelstiltskin said almost condescendingly.

"I can see that it's a horn," Regina said testily. "What is it for?"

"That, dearie, I am not so sure of," he said.

"It has powerful magic," she said, entranced. "I can feel it."

"As can I. But not the sort from the Enchanted Forest. This magic, it's something much older than that," he said.

"Older? Or from a different world?" Regina frowned.

"Both. A world that ceased to exist in 1949," Rumpelstiltskin said. "All but one woman who stayed in this world."

"Hm?" Regina said.

"Her name was Susan Darling. In her fifties or so I would say when she came here. She said she needed a curse lifted. And she would pay me with that. Well this was soon after first arriving in Storybrooke so I didn't have any magic, but once I felt the magic coming from that horn, I wasn't about to tell her that," he said.

"Where was this Susan from?" Regina said, turning the horn over in her hands. "Any world I've heard of?"

"I would think so. She's British," he said. Regina gave him a hard look. "Honest. Her accent was quite clear, and she told me so herself. But that is not where the horn is from."

"Then where did she say is it from?" Regina asked impatiently.

"She didn't. But I did find out what her maiden name was," he said slyly.

"How is a maiden name going to help me?" Regina demanded.

"Tell me, dearie. Did you ever read Henry a little series called The Chronicles of Narnia?" he asked.

"Of course I did. He loves fantasy stories. But how is – unless you are saying this Susan is supposedly Queen Susan of Narnia?" she said incredulously.

"She did say her maiden name was Pevensie, she's British, and she had that horn. Is it any stranger than any of the other stories here?" he pointed out.

"So if I blow this horn, some sort of help is guaranteed to come," Regina said, a slow smile making its way on her lips. She then frowned. "If Susan needed a curse lifted why did she not blow the horn herself? What curse was it anyways?"

"Do you remember how the story ended?"

"She remained in this world while her family went on to Aslan's Country," Regina mused.

"Indeed. Although as with all of our stories, it's not quite as people knew it to be. She did not become silly and frivolous as the books suggest. No, the moment I saw her I could tell that was far from true. And she tells me she was cursed for blasphemy, and that curse involved never going to the world her siblings lived in," he explained.

"Blasphemy?" Regina said in surprise.

"Alas, she didn't elaborate. But I looked into what I could find on her and apparently she was arrested for arson at a Church," he said.

"Huh. I like her already," she smiled, not too fond of religion herself. "So what did she want?"

"She asked me about portals into other worlds. While she never told me what world, she mentioned wishing to see her siblings, so I surmise she wanted to travel to Aslan's Country. Alas, without magic there was little I could do. Not that portal jumping is in my purview," he said.

"And yet you have her horn. What did you do to her?" she asked suspiciously.

"Do to her? Nothing. She gave it to me. She said it was for trying," he said.

Regina gave him a hard look.

"That is truly what she said," he said in response to her look. He found it hard to believe as well. "I felt there may be more to it, but she left it here. She said she might as well since without magic in this world it was useless to her."

"But now there is magic in Storybrooke," Regina said greedily, turning the horn over in her hand as she inspected it.

"I don't know exactly what it will do if it is blown in this world," Rumpelstiltskin cautioned.

"It is said to bring whoever blows it help no matter what," Regina said, raising the horn to her lips. All of Storybrooke shook with its magic. The residents looked about, fearful of what sort of spell had occurred now.

Two Kings and a Queen stood at the banks of the river.

"Did you hear that?" the young Queen said, turning to her brothers.

"Someone is calling us," the younger king said.

"But it's not her," the High King frowned.

"No, for she has no magic nor much belief in it. But should we answer the horns call we shall find our sister once more," the Queen said, reaching for a ripple in the air. Her fingers began disappearing and her brothers shouted out. "This is it. The horn created a portal."

"But do we answer it?" the High King pondered.

"Do we have any choice? She's our sister. It matters not who called us, we return if there is any chance of saving her," she insisted, stepping through the ripple.

The two brothers glanced at each other one more time before stepping through.

At The Lily Garden Retirement Home, an elderly couple was having tea out in the garden when the lady suddenly grabbed her husband's arm.

"What is it, dear?" he asked in concern.

"I felt it. Someone has used my horn," she said, her face glowing with the energy of a much younger, fiercer woman.

"Are you sure? After all of the years…I had given up hope," he said, taking her hands into his wrinkled ones.

"I'm sure of it. I feel a connection with it," she said, getting up excitedly, more quickly than she had in years. "We must go. My siblings…I know they will answer it."

"And my sister?" her husband said, gripping her hands even more tightly in fear.

"I know my siblings will do anything to help you get your sister back," she assured. "Don't worry, Michael. I'm sure they will be able to find Wendy and John and then all of us can go live in Aslan's Country together."
