Salty wind

In the morning, a fisherman was stranded in such a strange place. A cove he never knew. In his seafaring experience, this cove had no sign of humanity in it, not even a marking on the cold stones. He had his supplies which consisted of dry tacks, water, torches, nets and a harpoon. Eager to explore and fear of the unknown made him hesitate to go or sail back to civilization. Remembering his family's poverty, he risked it all because he would die anyway. Delving deeper into the cove, the stench was faint but significant. "There are drafts, there might be an exit"- he mumbled to himself. The torch glimmered, the harpoon was in the hand, he looked back and forth. Further away from the ship, the stench was getting stronger and stronger. Until…

"A corpse? That is a human skull. There are armors and weapons scattered. What happened here?"

He looked back again. Something was skittering. A metal item dragged against the stone was what he knew. In this kind of moment, anxiety and panic were overwhelming the poor soul.

Going back is what a normal human would do after acknowledging such a scene but something is behind him.

A strange wet noise sounded like a fish flapping its tail on the stone, he knew that then, those weren't humans.

"I should have gone home," he muttered in his thoughts, "I should make a run for it."

Combining all his torches into one big torch and rushing toward the ship, he did not look back. The metal hitting against the cove's floor, strange wet flapping noises and some sort of strange screeching were behind and echoed into his head. He set the ship, opened the sail. Praying the wind would help him escape. Something hit the ship? It did not matter, as long as he could get back to civilization to tell, he would not look back.

After getting back to the port, he kissed the port like the mad man he was. Everyone else seemed surprised about the strange spear sticking out on his ship's rear. He told what he had seen and heard at the tavern. Everyone seemed to be compassionate with his story. Buying him drinks was the only way to soothe him out of the narrowed death.

The cove's location remained unknown since the only survivor had gone mad and never wanted to go back to such horrors.
