I haven't actually read this specific fanfiction so I'm not sure about the exact plot. But generally in fanfictions, it might explore Harry Potter having some new powers or a special role as the 'Prince of Light'. It could involve new adventures, different relationships with the other characters, and perhaps a new take on the battle against Voldemort.
The plot could be centered around Harry's discovery of being the Prince of Light. Maybe it shows how this new identity changes his perception of himself and his place in the wizarding world. It might also include new magical abilities that come with this title, and how he uses them to protect Hogwarts and the wizarding community. It could also involve new characters or a different version of existing characters that are related to this new aspect of Harry's identity.
Since it's a fanfiction, the plot could go in many directions. It might start with some mysterious signs or prophecies indicating Harry's new role as the Prince of Light. Then, he could embark on a journey to understand what it truly means. Along the way, he might face challenges from those who oppose this new power or identity. There could be twists and turns in his relationships with friends like Ron and Hermione, as they also try to figure out how to deal with Harry's new status. And of course, it would likely involve a final showdown against some form of evil, with Harry using his newfound powers as the Prince of Light.
