Well, in such a fanfiction, it might show how Hermione's friendship with Ron is tested by Lavender's presence. Hermione may feel a sense of betrayal as Ron starts to date Lavender. It could also explore how Lavender misunderstands Ron's true nature at times, while Hermione truly knows him deep down. This can create a complex web of relationships within the story.
No. Harry Potter is a completely independent and original fictional universe created by J.K. Rowling. It has its own unique storylines, characters, magic systems, and world - building elements that have no relation to a 'Draken fanfiction'. The Harry Potter series is about a young wizard's journey through Hogwarts School of Witchcraft and Wizardry, facing dark magic and growing up, which is very different from what a fanfiction would be.
As of the current chapters, Draken is still alive. The storylines haven't led to his death. The character has played an important role and continues to be part of the ongoing narrative.
One possible plot could be that Harry discovers Draken through some magical means in the wizarding world. Maybe a spell goes wrong and he gets a vision of Draken's world and becomes intrigued. Then he starts to study about Draken secretly, against the rules of the wizarding society.
