  === Alys Karstark ===
  Alys Karstark is the only daughter and youngest child of Lord Rickard Karstark. She is betrothed to Daryn Hornwood, heir to the Hornwood, but Jaime Lannister kills him alongside two of her brothers. Her father offers her to whomever captures Jaime Lannister, so the sadistic sellsword Vargo Hoat captures Jaime in the hope of becoming Lord of Karhold. However, after Rickard's death his uncle Arnolf Karstark plots to take control of Karhold. He declares for Stannis when he comes North in the hope this will mean the Lannisters execute his great-nephew Harrion Karstark, so Karhold will pass to Alys, whom Arnolf intends to force into marriage with his son Cregan Karstark. Arnolf also intends to betray Stannis when the Boltons attack. However, Alys (pursued by Cregan) flees to the Wall seeking Jon Snow's help and reveals her uncles' plans. To protect her Jon imprisons Cregan and arranges for Alys to marry the Wildling leader Sigorn, Magnar of Thenn, in a ceremony performed by Melisandre, which will aid Wildling integration into the North. If Harrion dies childless, Karhold will pass to the newly formed House Thenn.
  In the HBO television adaptation, she is portrayed by Megan Parkinson.
