When you arrive at the fishing village, you encounter several places. The first is a monument to an unknown diety in the middle of the worn-down village. Travelling past the village you find large eye-like formation from the bones of the villagers. The text that pops up when arriving at the scene tells of " the meat picked off their bones". Going to the opposite site of the village you encounter a large blood splatter on the ground, and the text tells of someone (or someTHING) had a fight there. Heading towards the coast you find bloody foot/handprints of something that was human-like, ending the encounter. The Lights: part 2 triggers.

He orders you to keep your mouth shut about the whole thing, and orders his men to burn what's left of the village. Upon exiting the dialogue the quest ends. Rewards: 150 coins and 500xp
