When Xia Ya left the Pay-to-Win Ruins, the unconscious Yveline was carried on his back.

Unlike Synlos, the Dark Elf had no memories of the past, but the information she gleaned from their conversations was both chaotic and terrifying, intensifying her self-doubt.

With no other choice, Xia Ya had Synlos knock her out and temporarily sealed off that part of Yveline's memory.

Even without the current world, the abilities of the Destroyer of Worlds remained intact. He could freely access the memories of his followers and manipulate them. The instructions also included psychological tactics like "remove certain affections and hopes, deepen despair and fear."
