|Allegiance|| House Stackspear|
|Died||In 244 AC or 245 AC|
|Spouse||Ser Jason Lannister|
|Book(s)||The World of Ice & Fire (appendix)|
According to semi-canon sources, Jason Lannister deflowered Alys in 244 AC, getting her pregnant. Jason and Alys were married because of this, but Alys would eventually die giving birth to the child, named Damon. Alys's death in childbirth, however, is not described in the final edition of The World of Ice and Fire, and is thereby semi-canon.
