The earth shakes. And just to be clear, for reasons unrelated to dragons (big) or dragons (hot). No, the earthquake that has been going all this time -

The walls are moving. The building is moving. The entire segment of the Underworld is moving, and has been moving since before the battle began. And it's...

[i]Slowing down.[/i]

Blue walls (neon and black) give way to platinum gold. The screech of brakes fills the air. The ceiling gets higher, higher, higher - lights ascending to the point where they merge into a blue blur but still ascending even beyond that. Even the advertising walls push away, flickers in the dark, clearing the space for massive hazard light holograms to slam into place.

"As entertaining as this medievalist sideshow has been," came Adam's voice, blaring over loudspeakers in every direction. "It is time to demonstrate what all of the numbers and figures I have been quoting mean in practice. While you were studying the blade, I have been perfecting the art of day trading - and I have purchased [i]this[/i]."

Alarm claxons blare. Enormous robotic arms extend from the walls, carrying with them enormous bars of metal. The Servants grasp their weapons, ready for battle - but instead the arms form a massive grid. Power runs through them, an eerie hum of magnetism that causes pigeons for kilometers around to fall dizzy from the sky.

"Once I am established in space I will use the orbital defense laser array to crack the Vault and unleash the Harvest Star's potential," blared that wicked voice. "From above, I will uplift this backwards planet. All you have accomplished is forcing me into a fast takeoff scenario. <Laughing While Crying Emoji>"

And then the Space Elevator fires.

The entire Vault complex, the massive underground structure that contains the Harvest Star, blasts up into orbit on wings of ultramagnetism. Pipes crack and shatter, water floods down, electricity cracks and shorts out, and the massive robotic arms retract into the walls. A moment later flocks of whirring demonmechanical bees emerge from the walls to begin repairing the damage.

And the central holographic light resolves into a single screen:
