In an underground space very deep from the surface, resembling a natural cavern, seven or eight flat-bottomed cargo ships covered with tarpaulins were docked in a broad underground dark river, akin to the Mill River.
The dark river meandered into the distance, and judging by the sound of water, there seemed to be many tributary dark rivers joining in.
Meanwhile, many short figures were busily transporting boxes of ore from mining carts onto the cargo ships.
On a slightly elevated rock by the dark river's edge, a blond man dressed in a blue and white mage robe slightly frowned. He seemed to have received some sort of communication, turned around to look in the direction of the Azure Mine, and murmured lowly:
"Adventurers have come again as expected."
"However, the Detection Array showed no reaction, so there should be no Classes."
"It seems the death of that group of adventurers last time didn't concern the association much, which makes it easier to handle."
