Communication is key. In the fanfiction, they could start opening up more about their past traumas and fears. This would make them understand each other on a deeper level and bring them closer. Yrene could talk about her struggles in becoming a healer, and Chaol could share his experiences in the military and his complex relationships with other characters from the Throne of Glass series. By doing so, they'll be able to support each other better and their relationship will grow.
Another way is through facing external threats together. Maybe there's a new enemy in the fanfiction that targets both of them. They would have to protect each other and fight side by side. This kind of situation would force them to show their loyalty and love for one another. Also, they could start building a future together, like planning to start a school for healers or a training ground for soldiers, which would symbolize their combined efforts and shared dreams, thus strengthening their relationship.
Their relationship could develop further through shared adventures. For example, if they go on a quest together, they'll have to rely on each other, which will deepen their bond.
Their relationship can be developed by having them face more personal challenges together. For example, if one of them gets seriously injured and the other has to take care of them. This would deepen their emotional bond.
One idea could be that Chaol and Yrene go on a journey to discover a long - lost magic that could help save their kingdom. Along the way, they face various challenges that test their relationship and their individual strengths.
Their relationship could develop in a more angsty way. Suppose Chaol is forced to make a decision that goes against Celaena's wishes for the greater good. This could cause a rift between them, but also make their eventual reconciliation more powerful. Another development could be that they start off as rivals, constantly competing in various aspects such as combat or court politics. But as they get to know each other better, they realize that they are better off as allies and perhaps more. Additionally, if they are both exposed to a new culture or ideology, it could change their perspectives on each other and their relationship could evolve in unexpected directions.
Their relationship could develop further through shared challenges. For example, if they had to face a powerful enemy together, they would learn to rely on each other more. Celaena's fighting skills and Dorian's magic would complement each other, and this would bring them closer.
A plot could revolve around Celaena and Chaol getting caught in a time - warp. They find themselves in a different era of their world and have to adapt while also trying to find a way back. Along the way, they learn more about their own relationship and the history of their land. Also, a plot where they are forced to work with an old enemy to stop an even greater threat to their kingdom.
His character can be developed by exploring his past traumas in more depth. For example, his time serving under the valg could have left deeper psychological scars that affect his present actions and relationships. Maybe he has nightmares that he has to overcome, which could be a great way to show his inner strength as he battles his own demons.
Some Tumblr blogs are dedicated to sharing fanfics as well. You can search for Chaol and Yrene related tags on Tumblr, and you might find some great fanfic recommendations from the community there.
One interesting aspect is the character development. In fanfic, we often see Chaol and Yrene's relationship grow in unique ways. For example, their interactions might be more detailed and explore different emotions compared to the original work.
For Nesryn, her character could be developed by exploring her family background more deeply. This could add layers to her motivation and personality. For Sartaq, his relationship with his family, especially his father, could be delved into. This would show his growth from being a prince to a more complex individual.
Their relationship might develop through a series of challenges. For example, they could be forced to participate in a magical tournament together. In order to win, they need to trust each other completely. Manon has her own set of combat skills and Dorian has his magic. They must learn to combine their abilities. At first, they bicker and argue about strategies, but as they see the effectiveness of working together, they start to respect each other more. This respect then turns into admiration and finally love. Along the way, they also have to deal with the politics and prejudices of their respective worlds that try to keep them apart, but they fight against it and their relationship grows stronger.
