First-person FPV drone shot diving into a frozen arctic canyon during a violent aurora storm. The drone rockets over cracked ice sheets, slips through glowing blue glacier tunnels, and banks between towering ice spires as green and violet aurora light ripples across every surface. The flight accelerates toward a colossal frozen waterfall suspended in midair. At the final moment, the waterfall shatters upward into millions of luminous ice fragments, revealing a hidden alien ocean beneath the glacier. The drone plunges through the floating ice debris and bursts underwater into a glowing bioluminescent abyss filled with giant drifting light forms. Seamless one-take, extreme FPV speed, realistic inertia, aggressive banking, cinematic motion blur, high-end VFX finale, volumetric mist, refractive ice, surreal scale, ultra-photorealistic, blockbuster ending, no cuts.
