Answer:
A device for finding furniture in the dark.
A shimmering field that reaches far. Yet it has no tracks, And is crossed without paths.
I am nothing really at all, Yet I am easily foundΝΎ Ignore me at your own peril, and you might end up crowned!
I have rivers without water. Forests without trees. Mountains without rocks. Towns without houses.
Take off my skin, I won't cry, but you will.
I am a band that does not perform, sing, or act. What am I?
