Gragnokh, the World of the Iron Hell, was once a normal world.
The thing that made it different was the society that was absorbed with the notion of efficiency, work, and development.
Slowly, their society lost anything related to entertainment.
The people had only one thing in mind.
Work. Get more money. Increase your position in the society. Get better work. Get more money.
The cycle kept repeating.
People forgo everything else. Be it familial ties, or rest hours.
They went as far as cybernetically enhancing themselves so they could work more.
The world of Gragnokh and its people were judged as evil for infanticide.
The people create machines to replace them as the new generation. They had long since removed organs responsible for reproduction, which Tartarus judged as killing the children that could've been born.
"Killing children…."
Neo looked through the memories.
