Ghost Pirates of the Sea-erra Madre

You decide to head to the interior of the island. If there are dinosaurs here, you want to see them!

However, much to your surprise you soon encounter not a dinosaur, but a human! An elderly person in ragged clothes is sitting next to a fire pit

"Hello," you say to them, hoping that they're friendly. It turns out that they are, at first. When you mention that you first came to sea to look for Atlantis and explore the ocean depths they turn angry.

"I dedicated my life to marine biology," the person. "And those dolphins abandoned me on this forsaken island, unable to publish any of my research!"

"Maybe we can get off the island?" you suggest, beginning to worry for your own safety.

"I bet you're working for those dolphins, aren't you?" the disgruntled marine biologist says, reaching for a large stick on the ground next to them.

This isn't looking great for you, but this person is pretty old. You could try fighting them or you could run away.
