The core region or the meteorite was divided into two parts. One was where Zed, Sophia, and 90% of mutants went - the trial zones. It was vast - as big as hundreds of cities combined into one - with multiple layers. It was in this area that the so-called treasure vault existed... the ultimate place everyone desired.
The second part was the fantasy land where a negligible amount of mutants came. The fantasy land was equally vast, with multiple statues, ponds, gardens, ruins, fragments, spaceship relics, etc.
At the end of the biggest spaceship, there was an endless tunnel which lead to a separate space where the nanite mountain existed.
...
There was a complex look in Kiba's eyes as he glanced at the nanite mountain. He knew once he started, he would cross the line of no return.
He locked his eyes on the mountain and suddenly, it was replaced with a scene of Felicity... lying in a bed; under medically induced slumber.
