"Have you found a way to get through this fog?"
Brando leaned against the ship's rail, his expression grave as he stared at the wall of sea fog ahead and asked the question.
Wagtail Strait ran north to south. On a clear day, one could look east and clearly see the coastline toward Swallow Plain. But now, the central area of the strait was shrouded in a vast fog. The fog itself seemed completely motionless, like a wall standing perpendicular to the very center of the strait. Its boundary was sharply defined, as though it was entirely unaffected by the currents and sea breeze.
Brando looked up at the sky. The weather was clear, not rainy, and there was only a light breeze at sea. Besides, Mr. Liu had mentioned that the conditions in Wagtail Strait were always excellent. Based on Brando's limited knowledge of navigation, this was not the kind of weather that could produce sea fog.
An Undead Sailor lifted a thermometer from below the waterline and reported the reading to Tagus. The difference in seawater temperature was perfectly normal. True to the meticulous, by-the-book habits of a vampire noble, Tagus recorded the data and then handed it to Brando.
Brando glanced at it and thought, So it wasn't vapor formed by evaporation, either.
Everything pointed to the fog being unnatural. However, under unnatural circumstances, there were simply too many ways to create such a dense fog.
He first asked when the fog had appeared. Tagus told him that it had begun appearing on the sea not long after they set sail. It had been very thin at first, and they could still see the coastline of Swallow Plain when they looked east.
Not long afterward, the great explosion occurred at Rosalin Port. After seeing the flash, Tagus
