Mernars

The waves galloped toward the shores as Arthur stood on the highland. The stream below ran unceasingly, and rumors have it that the monsters here made all the people evacuate.

As Arthur looked around, his detection took a snapshot of the land. He could use it to gain a live perception of the terrain, but it would consume his mana. There were monsters indeed, a type that Arthur never saw the like of before.

"I guess it's time to weed them out," Arthur teleported toward a meadow, a piece of low land beside the river, where the monsters had a nest.

From Ma's report, Arthur learned that these humanoid-looking monsters were called Mernars, an aquatic humanoid monster that fed on human brains. That's why there were skulls scattered around the nest of either pirates or civilians.

The sight made Arthur sick, but he directed his rage toward the monsters in front of him. They sensed his existence and turned to see him taking a whip of fire out of thin air.
