William's whispers, although mostly factual, left certain details unclear or deliberately omitted.
Indeed,
The Fourth Disaster is timid due to absolute self-esteem issues, never daring to reveal its true form, always hiding in the gaps to spy on others,
It represents the lowest, cheapest form of evil.
Precisely because it's low and cheap with no threshold, almost anyone can accomplish it, and almost everyone's heart harbors more or less voyeuristic thoughts.
Its voyeurism spans all worlds, even infiltrating some planar gaps, even occupying the gaps of the [City of Evil].
It's because it spied on the [First Disaster] that the latter noticed this special and powerful 'evil' hidden in the deep.
Similarly, the First Disaster, like William, uncovered the essence of this Peeping Tom,
Specifically visiting and granting what it wanted most—"recognition," even giving it an advanced title like Fourth Disaster.
