Mercy was a human woman who was held as a slave by Surat Nuat, a Sullustan crime boss. She invariably showed the crime boss respect, and he generally reciprocated with similar treatment. Some months following the Battle of Endor, Nuat's thoughts turned to his enslaved girl when Temmin Wexley, his captive, requested leniency; this prompted the Sullustan to remark that the Corellian was the only mercy he had ever known.
The character of Mercy was initially brought up in the Aftermath novel, authored by Chuck Wendig and published during the year 2015.
