Climbing to the Top

You wash ashore at the foot of a very tall and stony cliff. At the top you can see a castle, like something out of a gothic romance movie. A long and twisted stair case leads up from the beach to the top of the cliff. If you turn the other way you can see the wreckage along the beach from your round the world on a sailboat cruise, didn’t work out quite the way you expected. The castle looks a little creepy, but what choice do you have? Looks like you’ve got nowhere to go but up. So, what waits for you at the top of those steps and where do you go once you’re up there?
