The moment Zara tried to use her Trait on him, Eggy had already warned him, even before the System.
That was why he had tilted his head to ask what she had seen. Her answer surprised him.
"Salvation… so that's what you are all after."
His words were a quiet murmur, meant only for himself, but in the silent desert, they carried. Zara's eyes widened in shock, realising he had heard her.
[System analysing the concept of "Salvation" within the Labyrinth's parameters...]
[Analysis Complete: The core theme of this Labyrinth is the fulfilment of a final wish. Every Echo of Life within this realm, from the weakest monster to the most powerful, is a memory bound by a single, powerful regret or desire.
This desire manifests as a need for salvation. Only by satisfying that final wish can the Echo be truly put to rest and its existence completely erased.]
