I'm not sure if there is an existing fanfic specifically about Corrin and Peri being pregnant. There are a vast number of Fire Emblem fanfics out there, but it would take some searching through fanfic platforms to know for sure. Some fanfic writers might be interested in exploring such a scenario, but it may not be a common theme.
In many 'fire emblem corrin x peri fanfiction', the plot may revolve around them facing challenges together. It could be battles within the Fire Emblem world or personal struggles. For example, they might have to deal with the politics of their respective kingdoms while also trying to figure out their feelings for each other. This combination of action and relationship development makes the fanfictions engaging.
One good 'fire emblem corrin x peri fanfiction' is 'A Bond Beyond Kingdoms'. It beautifully explores the relationship between Corrin and Peri. The story focuses on how their different personalities interact and how they grow together through various challenges.
Well, it could explore the relationship between Corrin and Peri in a new light. Maybe it would show how they deal with the news of the pregnancy, the changes in their daily lives, and how their friends and allies react. It might also involve some challenges they face, like protecting the unborn child during a time of war or political unrest in the Fire Emblem world.
Well, it's likely. Fire Emblem Heroes has a large and dedicated fan base. To keep these fans interested and also to attract new players, adding new stories is a great strategy. New stories can bring in new mechanics related to the plot, new types of battles perhaps inspired by the story elements, and also provide more opportunities for character development. They can expand the game's lore and give players more reasons to keep coming back to the game. So, it's very possible that new stories will be added in the future.
There's a good chance they will. Fire Emblem Heroes has been known for regularly updating its content. New stories can bring in new players and keep the existing ones interested. They might add new stories based on the popularity of certain Fire Emblem games or characters. For example, if a particular game in the series has a large fan following, they could create a new story related to it in Heroes.
The story in Fire Emblem Heroes is not overly long. If you focus just on the main plotline, it might take you a few dozen hours. But if you want to fully experience all the subplots and character arcs, it could take significantly longer.
It is often considered appropriate to write fanfic about 'Fire Emblem Heroes'. Fans can use fanfic as a medium to delve deeper into the lore of the game, develop characters further, or even introduce new concepts that could potentially enhance the overall experience of the game for other fans. But always remember to keep it within the bounds of good taste and respect for the source material.
I can't say for certain. However, looking at the trend of the game, they usually release new content every few months. If they follow the same pattern, a new story could be added in the near future. But again, this is all speculation and it really depends on what the developers have planned.
