One common theme is the celebration of new life. It shows Rhys and Feyre's joy and anticipation of becoming parents. Another theme could be protection. Given the often - dangerous world they live in, protecting the unborn child becomes a top priority. This can lead to many heroic acts from both of them.
Love is a very common theme. Their deep and passionate love for each other is often explored further. For example, how they express their love in different situations.
Perhaps there could be a storyline where they discover something extraordinary about the baby while Feyre is pregnant. Like the baby has a connection to an ancient prophecy. This would lead them to search for answers about what it means for their child and their world. They would have to deal with the pressure of this new discovery and also make sure that Feyre stays healthy and safe throughout the pregnancy.
One great rhys and feyre fanfiction is 'A Court of Shadows and Light'. It delves deeper into their relationship after the main events of the series. The author beautifully portrays their emotional connection and the challenges they face together in ruling their court.
A great idea for this fanfiction could be centered around the baby's naming ceremony. There could be a big celebration in the faerie court with different factions coming together. The baby shows some special signs during the ceremony, like glowing or making a special sound that is prophesied to bring great things to the faerie world. And Rhys and Feyre are filled with pride and a bit of nervousness about their baby's future.
Begin with a hook. For example, you could start with a dream that Feyre has about the baby's future. Then, introduce the baby in a vivid way, describing its appearance and any initial signs of its powers. Next, establish the relationship between Rhys, Feyre, and the baby. Show how they interact and care for the baby. From there, let the story unfold with different challenges and joys that come with having a baby in the faerie world.
I really liked 'Pregnant Feyre's Trials'. This fanfiction focuses on Feyre facing different challenges while pregnant. It shows her strength as she deals with court politics, threats from enemies, and still manages to take care of herself and her unborn baby. It's a story that shows Feyre's character development in a unique situation.
A common plotline is the challenges they face during the pregnancy. Since they are in a fantasy world, there could be magical threats that target the unborn child. They would then have to fight to protect their baby. Additionally, the relationship between Feyre and Rhysand might evolve. They could become even closer as they share this new experience, or they might face some minor conflicts due to the stress of expecting a child. For example, Rhysand might be overly protective, which Feyre at times finds suffocating.
I think Amren would be a great supporting character. Given her knowledge and power, she could provide valuable information about the pregnancy, especially if there are any magical or unforeseen elements. Also, Cassian could be there as a protector. He could train Feyre to be stronger during her pregnancy (in a safe way) and be on the lookout for any external threats. And Nesta could be a complex supporting character, starting off perhaps a bit jealous but then coming around to support her sister.
A plot could be that Feyre discovers some unique powers or abilities related to her pregnancy. For example, she might be able to communicate with the unborn child in a special way that gives her insights into the future or the magical world around her. Or perhaps the pregnancy is prophesied to bring great change to the land, and Feyre has to deal with the pressure and expectations that come with it. It could also focus on the challenges she faces physically during the pregnancy in a magical world.
