Narnia Escape Room Ideas

I work at a library and we are working on our fourth escape room. We are planning a Narnia themed room are a looking for some ideas. Our current idea is the following: You are one of the Narnians and have found your way into Spare Oom. One of the Pevensie kids in is trouble and you need to find another son of adam to help you save the kid in question. It would be implied Edmund is probably the one in trouble, afer all he always was.

Any other Narnia related plots or clues would be greatly appreciated.
