There is a warden on this ship. I don't know his true name, but he suffered an accident that caused him to lose a good deal of his own memories. He and I have been working to restore them.

In my world, I invented a machine designed to draw out memories of unwilling or unable participants. It was meant as an interrogation device but had the curious side effect of drawing out memories the user did not even realize they possessed, buried deep under layers of subconsciousness and impenetrable under most circumstances.

It's called the Aurora Chair. This warden and I are building one.
