There's not much to go on without actually reading the 'riyria graphic novel'. But if it follows common tropes, there could be a young, inexperienced character who is the central figure. They might be accompanied by an older, wiser mentor - type character. There could also be antagonists, perhaps a powerful sorcerer or a corrupt noble, who oppose the main characters and create conflict throughout the story.
Since I'm not familiar with the specific 'riyria graphic novel', the main characters could be named after the title, like Riyria could be the main character or there could be a duo named Riyria. Or it might have a protagonist who is on a journey and meets various other characters along the way, who then become important to the story.
