The forenoon sun of Eiders was a lot stronger than the morning sun. It shed its light on the ground through the window, causing a dazzling reflection.

Kozert was standing there looking at Kieran under the sun with a gaze of admiration.

Kieran, who got more information after dominating, Kozert frowned, but his furrowed brows eased up quickly.

He got enough pieces of information from Kozert already. Despite it not solving all his questions and doubts, it answered the majority of them.

Firstly, according to Kozert, humans and monsters lived together in this dungeon world, and dusk and dawn were the signal for both species.

During the day, humans worked.

During the night, monsters lurked.

Of course, it wasn't an absolute rule though.

When human populations reached a certain height, the monsters that lurked slowly went away even at night, like the Eiders of before.
