The door knob thing is very remarkable. There was a lady that took a picture of it from the outside, very earnestly, saying she knew all about it when I tried to tell her what I had read; she seemed to have come for it, more or less, just as I had come for the grove.

The nightlight can slowly change colour from purple to red and back again, or you can keep it at one of the colours if you want to. The Nazgul has one as well, but it's long instead of short and round, and on the blue/green spectrum.
