There could be other magical beings as well. Maybe the wizard who might know something about the Dark One's power and how to reverse it. Also, Henry's friends like Violet could play a role. They might be initially scared of him but then decide to help him because they believe in the good in him still. And don't forget about Hook, who has experience with dark magic and could either be an ally or an adversary depending on the story's direction.
In this fanfiction, characters like Rumplestiltskin could be very important. Since he was once the Dark One, he might be able to guide Henry in some ways, or try to manipulate him for his own purposes. Another character could be Belle. She has a deep understanding of Rumplestiltskin and might be able to offer some advice on how to handle Henry's transformation. And then there are the other residents of Storybrooke. Their reactions to Henry becoming the Dark One could range from fear to hope, and their collective actions could influence Henry's journey.
