Susa Wynn is a gaunt woman who has dark circles under her eyes. This may be due to the poor living conditions under which she suffers at the time.
Susa Wynn applies to Moiraine for the White Tower bounty as she and Siuan take information from women who have given birth around Dragonmount near the end of the Aiel War. Her infant son's name is Cyril.
While Cyril is way too old to receive the White Tower bounty, with Siuan's quiet encouragement Moiraine takes pity on her and adds her to the list after noticing that the woman is starving and her child looks sick.
