How does Robert Jordan use imagery in The Dragon Reborn?

Example of Imagery:

"'My poor Perrin,' she said softly. 'My poor blacksmith. You are hurt so badly.'
With an effort that cost more pain, he turned his head. This was the private dining room in the Star, and near one leg of the table lay a wooden carving of a hedgehog, broken in half.
'Faile,' he whispered to her. 'My falcon.'"
