The sudden descent into the Infinity Castle symbolizes a forced confrontation with deep-seated fears and long-standing enemies, pulling the characters out of structured training and straight into the heart of darkness.
One reading of this transition is that it represents the inevitable convergence of past choices, where every previous battle aboard trains or within hidden villages serves as necessary preparation for an inescapable reckoning.
