Ilona and Mason decided now that they had food, before they did anything else, they needed to find a more permanent place to construct a shelter. Their camp on the beach was completely exposed to the elements and anything else that stumbled upon them. With two swords and a little knife being the only weapons, Mason wanted to get them situated somewhere it would be easier to keep Ilona safe.
When the pair had washed up on the beach the night of the storm, they happened to have landed in a spot where the view of the rest of the island was blocked by a ledge a ways back in the jungle. Mason and Ilona decided they would need to get to the top of it if they were going to see what the rest of the island looked like and make the best choice of where to construct their new home.
