The thread Wren established through the permeable door changed things.
Not dramatically. Not overnight. The specific incremental change of a new channel opening where no channel had been — information flowing through it, slowly at first, then more steadily as the threading quality improved with use.
What the thread carried was not language.
Not even the System's between-frequency transmission register.
The thread carried — quality.
The specific quality of the between-space on the other side of the door expressing itself through the established connection. Not communication in the sense of content. Communication in the sense of presence — the between-space that had withdrawn making itself present through the thread the way a river makes itself present through the channel it flows in.
Wren described it to the group on the first morning after the door became permeable.
