To Search, To Capture, and to Reap
The four enemy races of Marble City had set a plan in motion, spanning decades to destroy it. The memories he obtained from the Crust-Mantle only detailed a small portion of the plan. Even if he wished to inform Psychic Ancestor Marble about it, he had to unravel all the details first.
Marble City was his home, his haven in this treacherous era. He didn't wish for anything to compromise its safety or change the status quo. Therefore, his prime objective was to obtain the details from the Crust-Mantles.
If he failed to find them, then he simply planned to use the Hoberman sphere to initiate a massacre in the Labyrinth and rake in a lot of Credits. From what Rakh Veera had told him, the fifth layer spanned an area equivalent to the military academy. Moreover, all the 100 paths joined into it at various locations. From the fifth layer, one could access all the paths.
