The game itself is plot of a final Baratheon, a son, that it is revealed to be part Targaryen. Mors wants to get the child off of his hands but keep her safe, and Alester has a deal with Queen Cersei, to give the baby up for a royal seat. In the end, Mors and Alester duel, following the reveal that Alester had killed Mors' family, whom he was tasked to protect. Based on who you play as, and a dialogue option, there's four endings. Mors can either give the baby to Varys, who brings it to safety, or take it himself, where he raises it in his cottage, but will be followed by the Night's Watch throughout his life. Alester can also give the baby to Varys, and be royally executed, or give the baby to Cersei, after which he lives on his royal throne with depression.
