A/N- Based on a random, multi-fandom chatzy thing I did a few months ago. Enjoy!
Nimueh paused from her enchantment as she thought she heard a noise.
"Is someone there?" she called out with a frown. People didn't normally just wander into the Caves, and no one had ever gotten this deep without her to guide them. She stepped away from the pool of water reflecting her spell to glance out a one of the narrow corridor leading to this chamber, her figure silhouetted in the flickering firelight around the room. When no one responded, she just put it down to the strange apparitions that were occasionally attracted to the Old Magic.
Suddenly a strange woman in unusual, elaborate dress appeared in the cavern right in front of Nimeh. Nimueh drew in a quick breath.
"Who are you?" she said sharply.
The woman didn't respond straightaway. Instead, she looked about her like she struggling to accept what she was seeing.
"Where am I?" she responded, eventually.
Nimueh opened her mouth to respond when two men, one in some unusual kind of long jacket and the other in completely alien get-up, were suddenly there too. The man in the long jacket raised his head from where he'd found himself leaning against the wall.
"Where am I?" he frowned, and Nimueh responded without thinking.
"You're on the outskirts of Camelot. Where did you come from?" she added, suspiciously.
The woman stepped forward, gracefully Nimueh noted.
"Camelot? But I am an Elf and I've never heard of-"
"London, of course!" the man in the long jacket interrupted the 'elf' to answer Nimueh's question. Nimueh scrutinized them both and frowned.
"Elves? The elves died out centuries ago! And what's London? I've travelled all over this country, and yet I have never heard of this place…"
"London's the capital. What year is-" the man started before noticing the other stranger who'd arrived with him."Oh. Moriarty."
The 'elf-woman' chose to ignore the strange men, and instead spoke directly to Nimueh, obviously seeing some similar qualities they shared that Nimueh had noticed in her too.
"Elves are very much alive. With Sauron no longer alive, nothing can impede our survival."
Nimueh turned her back on the men. "Sauron? I have never heard of any Sauron. Was he a powerful sorcerer?"
Behind her, Nimueh heard the second man, Moriarty, get up, brushing the dust off his unusual clothes.
"What's going on?" he said in a demanding tone, ignoring the man beside him who'd clearly recognized him. No one responded.
Nimueh was struggling to keep up now. Three strangers had just appeared in a place no one can ever find. Ever. And none of them seemed to understand the world they were in. She ran a hand through her hair and stepped back so she could see the men.
"What are you?" she demanded in a desperate tone, "I have no knowledge of creatures such as these? Are you creatures of magic? Answer me!"
The woman stepped back in shock at her angry tone.
"You've never heard of Sauron? He almost controlled Middle Earth and drove the elfkind to the sea!"
Moriarty was now frowing and looking around in confusion, and Nimueh thought a little irritation.
"Will someone explain exactly how I was brought here, and who the hell you all are, before I decide you're not useful?" he demanded.
Nimueh drew herself up, "I am Nimueh," she declared, " High Priestess of the Old Religion."
Moriarty rolled his eyes, "Oh, God. Relgious nutjobs. The joy…" he muttered.
"That sounds like a threat, " Nimueh said, stepping towards him, "What exactly are you going to do against the most powerful sorceress you will ever meet, little man?"
"You can't be serious?" he laughed back, but Nimueh refused to see any humour in the topic.
"Magic has no place for joking under Uther's rule." She stated.
Moriarty responded by pulling out some kind of metal thing from his pocket and aiming it at her arm. There was a loud bang, and Nimueh felt a sudden, intense, pain.
"Well, this is dull, but there's an example for you." He said.
