A 'Swan Queen' fanfic usually involves the relationship between Regina (the Evil Queen) and Emma from 'Once Upon a Time'. 'A fine line' could imply a story that explores the delicate or complex nature of their relationship, perhaps the fine line between friendship and something more, like love or rivalry. It might also touch on the moral and emotional boundaries they cross in their interactions within the fan - created story.
One idea could be to explore how Regina's pregnancy changes her relationship with Emma. Maybe they become closer as they prepare for the new addition to their family. They could face challenges together, like dealing with the reactions of the townspeople in Storybrooke.
Fanfiction.net also has a decent selection of 'Swan Queen' fanfic. However, the quality can vary more compared to AO3. But it's still worth checking out as there are some hidden gems there. You can browse through different categories and use the search function to narrow down your search to 'Swan Queen' stories.

There could be a 'dragon swan queen fanfic' where the swan queen is in trouble and the dragon comes to her rescue. The dragon might use his fire - breathing ability to fend off enemies that are threatening the swan queen's kingdom.

First, you should create detailed backstories for both the dragon and the swan queen. Think about their personalities, for example, is the dragon more of a solitary type or a social one?

It could be a fantasy world where different species co - exist, or a more specific place like an enchanted forest.
