Oh yeah I realized this a while ago and forgot to say anything here (it was mostly just in discord server and some youtube comment) but anyway
Ever Higher leitmotif, I was thinking about what the fuck it could even represent, it's in Crumbling Tower, so climbing up walls? Nope it's in From Now On, something with the prophecy? Why the hell is it even in Every Higher?
And then I realized. It's not about the prophecy.
It's about stories.
There's that one Cuptain that was talking to Bilblox and went:
* I came here to seek the sage's advice on my journey. * Surely this legend shall make me a righteous hero. * If it doesn't make me a righteous hero, then it really sucks.
Most, if not all of the cuptains are like, trying to be heroes, rescueing their princesses, so I think I can assume this apply generally to all of them, at least for the theme.
(Meanwhile the book guy just recite that A is for Apple or something.)
And where else does it play?
Dark Sanctuary, From Now On, Crumbling Tower, SPAWN, GUARDIAN, Second Sanctuary, and Third Sanctuary
The place where you learn about the prophecy, and enact its story, all according to its words.
Being the heroes of deltarune, fighting enemies, trying to get the Knight, fighting the Titan and sealing it.
All while learning about the prophecy.
It's about following the role you think you are, according to the stories that you heard.
It's the roleplaying motif.
