The main characters could be the Lady of the Lake herself, who is central to the story. There may be knights like Lancelot or Gawain if the graphic novel delves deeper into the Arthurian court. Also, other magical beings or sorceresses related to the Lady of the Lake's world could be main characters, as they would add to the magical and complex nature of the story.
Obviously, the Lady of the Lake is one of the main characters. King Arthur might also be a major character as his relationship with the Lady of the Lake, especially regarding Excalibur, is a significant part of the Arthurian legend. Merlin could be in it too as he is often intertwined with the events and characters in this mythology.
The Lady of the Lake is surely a main character. Then, depending on how the story is told, Arthur and his closest allies and enemies would likely be main characters. For example, Mordred, Arthur's nemesis, could be in it. And if the graphic novel focuses on the more magical aspects, other characters from the realm of magic, perhaps those who serve or oppose the Lady of the Lake, would be main characters as well.
Well, often in such mystery novels, there's a central investigator figure. This could be a private detective or a police officer. Then there are likely to be characters related to the lady in the lake. It could be her friends, enemies, or family. There may also be some witnesses or locals who play important roles. They might provide key information or mislead the investigation, adding to the complexity of the story.
The main characters would surely include the Lady of the Lake herself. And in an Arthurian context, King Arthur is likely to be a main character as his story is closely tied to the lady. Merlin, the great wizard, may also be a main character as he has connections with both Arthur and the Lady of the Lake.
The lady in the lake is of course a crucial character. Then, there could be a journalist character who is trying to uncover the truth about the lady. This journalist might interview people and dig deeper into the mystery. There might also be a character who is a bit of an outcast in the community but has some secret knowledge about the lady in the lake.
Since it's a story about treasure in a lake, there might be a young and curious character, like a teenager. They could be the one to initiate the search. And there may be an old hermit who has some knowledge about the treasure's origin but is reluctant to share it at first. There could also be some villains who want to steal the treasure from the protagonists.
There's no way to know precisely without reading the graphic novel. But it's possible that there's a hero - type character who is trying to save others from the lake of fire. Maybe there's also an antagonist, someone or something that is causing the chaos or danger associated with the lake of fire. The characters could be complex, with their own backstories and motives that are slowly revealed as the story in the graphic novel unfolds.
Ron could be another main character. He might be hesitant or skeptical about the Lady of the Lake at first. And of course, there could be new characters created specifically for the fanfiction.

The main character is Lady Death herself. She is a central figure driving the plot.
The main character is likely Lady Amalthea. However, in a graphic novel, there are often other important characters to drive the story forward.

And of course, there could be a villainous character with his or her own motives and backstory. These characters would interact with Lady Amalthea, creating conflict, drama, and character development throughout the graphic novel.
