What is unusual is that Ruburt was able to use his perceptions fully to see within the patterns of the physical system, or to see through them to the patterns formed by another system.

The woman left your own physical system not long ago, according to your terms. She had a connection with this house, though not with you. She was a friend of the woman above you.
