Create an ending to the story: Once upon a time, there was a little girl who lost her favorite doll in the forest. She searched everywhere but couldn't find it.

She finally found a small stream and followed it until she reached her home. It was a relief for her and she learned to be more careful next time.

She might have discovered a hidden fairy glen in the forest. There could be tiny fairies with gossamer wings flitting about. She could befriend them and they would show her secret paths and magical plants. Every day, she would return to this enchanted place, learning more about the magic of the forest from her new fairy friends.

She could be on an adventure to find a hidden treasure in an enchanted forest. Maybe she follows a mysterious map that she found in an old attic. Along the way, she meets talking animals that help her overcome obstacles.

She is found by a kind - hearted ranger who takes her back to her family.

One common theme is the exploration of different mythologies. Both shows have rich mythologies, and in fanfiction, authors often combine or contrast them. For example, the fae lore from 'Lost Girl' and the fairytale magic from 'Once Upon a Time' are often blended to create unique storylines.

She walked towards the cottage. When she got closer, she saw an old woman at the door. The old woman took her in, gave her some food and helped her find her way back home.

As she walked deeper into the forest, she got a bit lost. But then she noticed a strange light. Following it, she came upon an old, wise owl sitting on a branch. The owl told her stories of the forest and showed her the way back home, warning her not to venture too far alone next time.

Bo is the most obvious choice as she is the central figure. Writers often explore her character in depth, her struggle with her identity as a succubus and her place in the Fae world. However, Trick is also a popular character to write about. His wisdom and the secrets he holds about the Fae history can create really engaging storylines. Additionally, Hale, with his musical abilities and his role in the Fae hierarchy, can be an interesting character to focus on in fanfiction. His relationships with other characters, especially his loyalty to Bo and Dyson, can be explored in many ways.

She knew she had to return the magic key to where she found it. As she walked back through the forest, the animals thanked her with little gifts. When she reached the old wooden door, she put the key back. But this time, the door didn't close. Instead, it became a permanent entrance to the enchanted forest. From that day on, she could visit whenever she liked, and she became the protector of the forest, sharing its magic with other children in her village.

Well, it could be that the little girl faces some difficulties in the village, like dealing with mean kids or trying to find a way to help her poor family. She might then go on a journey within the village to find solutions to these problems.
