Fanfiction can provide a sense of continuation. Since their own story might have ended, fanfiction gives them the opportunity to be part of new tales, with new challenges and emotions. It also lets them explore aspects that weren't fully developed in the original story, like their deeper friendship or potential romantic feelings.
One common theme is the exploration of different cultures. Since Lucy is from one part of Narnia and Caspian has his Telmarine roots, their marriage often involves melding these two different ways of life.
There could be various fanfictions they might like. For example, adventure - themed ones where they go on new quests together in the magical world. Maybe fanfictions that explore their unspoken feelings for each other in a more in - depth way than in the original stories.
In this fanfiction, Caspian and Lucy's wedding was a grand affair. It took place in a beautiful meadow filled with wildflowers. The Narnians had prepared for weeks. Caspian was dressed in his finest armor, polished to a shine. Lucy wore a flowing white dress. As they exchanged vows, the animals of Narnia watched in awe. The Beavers were there, beaming with joy. The centaurs stood tall as guards of honor. Their love was like a bright light in Narnia, and everyone knew this union would bring new hope and strength to the land.
One possible plotline could be that Lucy and Caspian are newly married and the pregnancy is a surprise. They then have to deal with the political implications in Narnia as well as their own personal fears and joys. Another could be that they face some sort of danger during the pregnancy, like an enemy threat that endangers Lucy and the unborn child.
The relationship between the baby and the other characters in Narnia could also be developed. The baby might befriend the talking animals like Mr. Tumnus. This friendship could make the baby more connected to the world of Narnia, and also make the other characters more protective of the baby. As a result, Lucy and Caspian would have more interactions with these characters, strengthening their relationships in the process.
One idea could be that the baby has a special power. For example, the baby might be able to communicate with magical creatures in a way that no one else can. This could lead to all sorts of adventures as Lucy and Caspian try to protect the baby from those who might want to use the power for evil.
In the fanfiction, after getting married, they may face challenges in terms of leadership. They need to make decisions together for the good of Narnia. But their different perspectives - Caspian's Narnian - born knowledge and Lucy's insights from her own world - might sometimes clash. Also, there could be external threats. Enemies might see their union as a weakness to exploit or a new power to fear. They would have to work hard to prove that their marriage strengthens Narnia rather than weakens it. And on a more personal level, they may struggle to find time for each other with all their royal duties.
