Ok so I had a room based off of these series of books by Jayne Castle and her Ghost Hunters series. Basically it's like 400 years in the future and 200 years ago Earth was able to travel through this Curtain of energy and settle on another planet called Harmony. The curtain closed leaving the settlers stuck on Harmony. Survival was needed, and it threw the settlers into a period of primitive lifestyle. Now 200 years later they are able to have a lifestyle that is more comparative to modern to slightly in the future lifestyle. What also has been growing is the people have begun exihibiting paranormal psychic senses, and there is an extinct alien race that has some remnant energy floating around called "ghosts" and getting caught in this energy is painful and potentially deadly....that's where "ghost hunters" come, and these are generally big tough, and some would say even rough men who can creat the same energy and subdue the "ghosts". There are also "tanglers" that can undue the energy traps that are often found in the catacombs under the city-states that were formed by the early settlers. There are some other more obscure abilities that I can describe with interest.
