The dark side of her... {Completed} {Editing}

Key information

Marinette paced up and down in her room while Alya sat on her bed.
"So your saying, you want to write a fanfiction about a heroine called Ladybug?" asked Marinette.
"Well, it might be cool. Why is this such a big deal?" she asked.
"Have you been having dreams... about another life... maybe?" she asked, stammering a bit because she thought Alya would think she was crazy.
"Yeah. I thought it would help me make sense of them," she said shrugging.
"Well... this is new. Ok, I think I can help you," she breathed.
"Honestly, not a big deal," giggled Alya and she got up.

She walked out of Marinette's room and then a sudden burst of energy crashed into her head. It made her dizzy and she collapsed.

Marinette fainted but woke up in the most darkest place she had been in her life. It was like she was asleep.
"Marinette." A quiet voice but very familiar started calling her name.

Marinette started walking around.
"Hello? Plagg? Mum? Tikki?" she asked, calling out to the voice.
"That last one!" came a voice behind her. She quickly turned around to find Tikki.

"Tikki!" she gasped. She ran towards her. Tikki held her little hand out to stop her.
"I have very little time to explain. You must listen. As you already know, this universe shouldn't exist and I have been captured. Hawkmoth isn't the one who trapped me but he did work for them for a short period of time before they betrayed him. But now, they have me and wiped Hawkmoth's memory!" she explained.
"Who? What is their name?" asked Marinette.
"L...V... I can't say. This communication won't allow it. Anyway, you must find Master Fu. Any kwami holder remembers their universe! Find him and he will tell you more! Good luck Mari," she explained and disappeared.

"No, Tikki! Come back!" she wailed. Her eyes fluttered open.
"What happened?" she asked.
"You collapsed when Alya went out. She called us and brought you some food," smiled Adrien.
"Thank you," she smiled as she tried to get up.
"I wouldn't suggest it yet. We don't know if you have concussion or not," said a voice.
She looked at the side of her! Oh yeah, Gabriel Agréste is her father. She forgot!
"I'll be fine Father. Really," she said and got up, ignoring the pain she was feeling.
"There's my strong girl," he smiled.

Adrien and Gabriel walked out leaving Marinette to deal with Plagg's moaning. Well, this time it was questions.

"What happened to you?" he asked.
"Tikki."
"Where is she?" he asked.
"Not sure."
"Well, what are we supposed to do?"
"Go to Master Fu."
"Do you know where he lives?"
"Yes, Tikki took me there twice."
"Ok. Let's go. One more question. Chat Noir or Marinette?"
"Marinette."
