It is a quiet, rainy day. The world holds only a faint light as gray clouds fill the sky. The endless long corridor is made of cold marble. Stone pillars that have endured countless ages stand at regular intervals, and beyond them, green plains soaked in rain stretch out infinitely. Whenever the wind blows, the grass in the fields sways like gentle waves, and even the distant hills are submerged in rain mist, their boundaries becoming blurred.
