After bidding Boss farewell, William gradually calmed down and dispelled his fear before leaving the fur-covered underground area and heading for his department's designated location—the Acrobatic Troupe.
As he walked through the castle-like corridors, William clenched his fists and punched the air repeatedly, unable to hide his excitement.
His excitement wasn't because Boss planned to pass the circus on to him, but because she was no longer pursuing the matter of his month-long late return. She had even granted William an additional month's leave.
That meant he could return to Zion together with Jin.
However, William had also obtained several important pieces of information from their conversation. The first was the "Prehistoric Abyss" Boss had mentioned. Before the war had even begun, with the Evil Sun hanging overhead, an abyss had still somehow formed—and there were actually two of them.
One was the dark origin of all things in the world, as well as the place where death had first appeared: the Original Tomb.
"The First Dead was actually the Evil Sun's Eldest Son,
"while the Bonfire Mountain Range that blocked and isolated the dead was formed by the Evil Sun's second son.
"No wonder there was a huge stone stele standing before the bedroom of the First Dead at the Lowest Level of the Original Tomb. It was named 'For My Eldest Brother,' and the area before it was covered in flowers.
"As the Evil Sun's eldest son, he had actually turned his back on the sunlight and embraced darkness..."
The more William thought about it, the more interested he became in the events of prehistory.
"There was also Boss, who began pursuing darkness after witnessing death descend upon the Old World.
"She had become an abyss herself in an almost impossible manner and redefined the Old World's fear.
