Another theme could be self - discovery in a more complex and often harsher adult world. The characters may have to face their inner demons and past traumas, unlike in the original where the self - discovery was more about finding courage in a fantastical realm.
One possible theme could be complex relationships. In an adult version, the relationships between the characters might be more nuanced, like romantic entanglements with deeper emotional conflicts compared to the original which was more focused on a child's adventure.
One possible theme could be the concept of eternal hope. In a never ending story, there's always room for things to get better, no matter how dire the situation seems. It gives the idea that hope should never die.
One possible theme could be perseverance. If Nanuk is the main character, it might face continuous challenges and keep going, which would represent the idea of never giving up.
One possible theme could be eternity. Since it's a never - ending story, the idea of time without end might be explored. Another could be the cycle of life, with events or characters going through an unending cycle of change and recurrence.
They would likely be more morally ambiguous. For example, the hero might have to make difficult choices that involve some level of self - interest or compromise, not just pure good - versus - evil decisions like in the original.
Love could also be a theme, not necessarily romantic love but a deep love for each other as friends or family - like. They might support each other unconditionally, and this love could be what keeps their story going. It could also be about perseverance, as they face various challenges in their story but keep moving forward.
Well, it could be about a dark secret. Maybe something like a family curse that has been passed down through generations and the protagonist is trying to break free from it.
It could be a description of a magical place, like 'The first line of never ending story led to a land filled with glittering trees and talking animals.'
It could refer to a very long and perhaps convoluted narrative that seems to go on without end, like an epic saga with countless sub - plots and characters.
One answer could be that the story continues with new characters emerging all the time. For example, in a fantasy never - ending story, new magical creatures might be introduced as the plot unfolds. Each new character brings their own backstory and goals, which keeps the story going.
One possible theme could be self - discovery. The princess might be on a journey to discover her true self as an adult, away from the naivete of her youth.
