You are a captain. You were just controlling the ship, while your crew was sleeping for the night. You weren't tired, so you kept watch of everything. It is midnight, and you could barely see, and the only things lighting up the place, were the few torches on the ship. The waves aren't as strong for today, so you mostly only stood there to make sure no sharks attack the ship.

After a few minutes, of complete silence and boredom, you felt watched. You didn't hesitate to take out your sword just in case. You kept watching, until you saw at the edge of the ship, a hand crawling out to grab onto the floor. After a few seconds, something pulls itself up. It was hard to see what it was, so you approach it with a torch in your hand... After approaching it, you see... a fish? No, that isn't a fish! Further examination there was a body, and then you got to the face and it grinned at you.

"Heya! I'm Agetha!"

They introduced themselfs, you were confused and a bit annoyed. Either you can stay calm, or attack them.
