GR translation: social eye

[Mike Jing]

P148.6-9  Had he felt her, even then, beginning to recede...called up the control from across the Wall as a way of holding on?  She was deepening from his waking, his social eye like light at the edge of the evening when, for perhaps a perilous ten minutes, nothing helps: ...

Lots of questions here, so please bear with me:

Here "she" refers to Nora Dodson-Truck, is that correct?

Who called up the control as a way of holding on, "she" or Eventyr?

What is her "deepening"?  Is his "waking" referring to the awakening of his talent?

What is "his social eye"?

Thanks in advance.
