A thousand years later, people abandoned the old and welcomed the new world.
Mechanical ascension is no longer an empty talk - only limited to those at the top. The people at the bottom are just transformed.
The greenhouse effect has caused most of the glaciers to melt, and many once prosperous areas have been submerged, making it almost impossible to survive on the ground.
But no one cares.
People either embrace the sky or return to the embrace of Mother Earth, each seeking refuge.
"I" - the "relic" of the old world, woke up again and embarked on a journey.
The starting point is the end point, and we will eventually return to our roots.
