Look around the room some more

From Reddit Choose Your Own Adventure

Distraught by what you just saw, you decide that the next best thing is to look out for yourself. You look around the room for clues as to where you are, or what is happening around you. You walk around the outside of the lighthouse, all you can see is the town and the forest on the mainland, and the vast ocean on the other side. With no new information you decide to look inside the room. Inside you find a small table and chair. There is a jacket on the back of the chair, only now you realize just how cold you are. You try the jacket on. It is a bit large but it is warm and makes you feel instantly better. On the table there is a book, The timeless deeds of Izgharan the mighty. You flip through the pages, most of it is just stories of this character Izgharan, yet they seem to be set in Trathia, and so you wonder if the book is supposed to be fiction or not. As you are about to put the book down a small note falls from the later pages, the numbers 6-13-17 written on it. You have no idea of the significance of the numbers, yet you put the note in your pocket.

With the room fully explored, you decide to head back down the stairs.
