The mysterious person sitting between the cliffs, fishing,
was wearing a white suit that didn't conform to "The Tombs."
Moreover, Han Dong wasn't seeing things; the fishing rod in their hand could truly reach the starry sky, as if they were engaging in 'Interplanar Fishing,' though it was unclear what they could actually fish out.
The mask worn on the face of the mysterious person
was the Vortex Mask that Han Dong was all too familiar with, found throughout the Black Tower... and it was the white vortex that symbolized the 'upper echelons' of the Black Tower.
"You are! The Administrator!"
This was not the expected Moon God, not some Mythic Body being.
It was the Administrator from the high levels of the Black Tower that Han Dong had met beforehand.
At first, when Han Dong chose the task file for "The Tombs."
Because the world numbered M-0031, "The Tombs," belonged to the early 'Self-created World' rather than an 'Outward-recruited World.'
