CHAPTER I −2,400 m · 2.4°C · 240 atm

A Quest Begins
in the Deep.

The journey starts where light forgets — on the silt of the deep, where spiral shells whisper a chronology older than continents. Sora means sky, but every sky is born from a sea.

Pressure 240.0 atm
Visibility < 0.5 m

CHAPTER II 0 m · sea level · 15°C

Crossing
the Mirror.

A thin film of silver — the boundary that splits worlds. Above it, salt becomes cloud. Below, sunlight becomes shadow. We step through the mirror and the journey accelerates.

CHAPTER III 3,600 m · −2°C · cumulus deck

Through
the White Halls.

Vapor cathedrals drift past the window. Each cloud is a slow draft of weather still being written. The world below softens to a quiet blue map and the engines steady into a hum.

CHAPTER IV 11,000 m · golden hour · cruise altitude

Where the Light
Bends Gold.

The horizon ignites. A long, slow ribbon of amber wraps the curve of the Earth. From here you can see two weathers at once — the storm to the north, the calm to the south. Geography becomes story.

CHAPTER V 100,000 m · Kármán line · −86°C

The Atmosphere
Lets Go.

The blue thins to violet, the violet thins to ink. By definition this is where flight ends and orbit begins — the Kármán line, a polite fiction drawn across a sky that does not believe in borders.

CHAPTER VI 408,000 m · 7.66 km/s · LEO

The Overview
Effect.

Sixteen sunrises a day. The borders disappear. The ocean we started in is a curve of colour the size of your thumbnail. The quest, you realise, was never about leaving — it was about learning to see.

A Quest
Without End.

Sora.quest is an open invitation: travel the column from shell to star, from pressure to vacuum, and find that the line between them is only a matter of where you choose to stand.
