The OC can be developed by showing their initial fear and confusion when they first hatch the dragon. For example, they might not know what to do with this powerful and dangerous creature at first. As time goes on, they learn to bond with the dragon, which in turn builds their confidence and sense of purpose.
One interesting plot twist could be that the OC who hatches the dragon is actually a long - lost heir to an ancient and powerful family. This family has a secret connection to the dragons, and the hatching of the dragon reveals their true heritage, leading to a power struggle among the other noble houses who fear their rise.
Well, in the world of 'Game of Thrones' fanfiction, the possibilities are almost endless. Since the show and books have such rich lore and a large cast of characters, it's not surprising that someone would write a fanfic where Arya hatches a dragon. This kind of plot would likely involve some sort of magic or unforeseen event that leads to Arya coming across a dragon egg and then having it hatch. It could also potentially change the entire course of the story in the fanfic, as Arya with a dragon would be a very powerful force.
It might be really exciting. Arya could use the dragon to seek revenge on her enemies. The dragon could also protect her during her travels and adventures.
If Jon Snow hatches a dragon in the fanfic, it would completely disrupt the power balance in the Game of Thrones world. Dragons are extremely powerful creatures, and having one on Jon's side would make him a formidable force. He could use it to quickly travel across Westeros, intimidate his enemies, and gain more support. This would likely cause other rulers to either try to ally with him or plot against him more vehemently. The Night King and the White Walkers would also have a new and dangerous adversary, as a dragon could be a very effective weapon against them.
The origin of the egg might be a mystery left behind by some ancient civilization in Westeros. It could have been hidden for centuries and the Starks just stumbled upon it. Another possibility is that it was smuggled out of Essos by someone who thought the Starks could keep it safe. It could also be a relic from a time when dragons were more common in Westeros, and the Starks were meant to be the ones to revive their power.
A more intense bonding scene could involve the OC having to save the dragon from a trap or danger. As he frees the dragon, there is an immediate sense of gratitude from the dragon. The OC then uses his knowledge of dragon lore (which he could have learned through years of study) to soothe the dragon's wounds. This act of kindness and rescue creates a strong, unbreakable bond between them, and the dragon becomes fiercely loyal to the OC.
I think it could be the blacksmith OC who has a strong moral code. For instance, an OC who refuses to make weapons for evil lords or sells his work only to those who he believes will use it for good. This type of character adds depth to the fanfiction and can be very appealing to readers who like complex and morally upright characters.
It would change the power dynamics completely. With dragons, Jon Snow would be a much more formidable force. He could easily overpower his enemies. For example, if he faced Cersei, his dragons would give him an edge. This would also make his claim to the Iron Throne stronger, as he has such a powerful asset.
OC Myranda in fanfiction could be used to explore different relationships. For example, she could have an unexpected friendship with a character that was her enemy in the show. This could lead to some really cool plot twists. Also, the author could change her role in the political intrigue of Westeros. Instead of being just a tool for Ramsay Bolton, she could become a key player in her own right, manipulating the power dynamics in a different way.
