This device permits you to "log on" to the "dark side" of the world's chi energy. Thus you can access memories and psychic impressions of places and events, just as long as you know where to look. You can ask complex questions of your GM, who will answer them in foreboding ways or describe to you dark visions that you get. You can do research using Powers as if if you were using Investigation and working in a library of dark arcana.
