As Astra and Nell's voices resonated through the chaotic symphony of cosmic forces, the air itself seemed to crackle with an otherworldly energy. The island, now a nexus of dimensions, pulsed with arcane power as the celestial and sea monsters converged around it. The impending clash of colossal forces painted an awe-inspiring tableau against the blood-red canvas of the sky.

The celestial beings, with wings that spanned the horizon and bodies wreathed in celestial fire, descended with an ethereal grace, adding a celestial ballet to the unfolding cosmic drama.
