I'm not entirely sure as I haven't read it yet. But generally, a graphic novel in a series like this might be about a hero's journey, with battles, magic, and a struggle between good and evil.
The main characters could include a hero who wields the power of the lightbringer. There might also be villains who oppose the hero. There could be side characters like wise mentors, loyal friends, or other characters with their own motives and backstories that interact with the main character and help drive the plot forward.
One idea could be exploring the origin of Lightbringer in more depth. Maybe it was created by an ancient civilization long before the events of 'Game of Thrones'. Another could be a story where a new character discovers Lightbringer and has to learn how to control its power without succumbing to its dark influence.
Daenerys Targaryen would be fascinating. She has her own dragons, but Lightbringer could be the key to truly uniting the people of Westeros under her rule. It could symbolize her rightful claim to the Iron Throne and be a tool to overcome any remaining opposition.
