|First appearance:||All Change|
Aslaug is the second wife of Ragnar Lothbrok and the mother of his younger children. Aslaug has a "gift": like a völva, Aslaug is some form of a seeress who sees the future through visions or prophecies.
Ragnar, distressed and upset over the loss of his son with Lagertha due to a miscarriage, takes a pilgrimage to Uppsala, hoping to seek answers from the gods. Ragnar also begins to wonder who will be the mother of the many sons the gods promised him if it wasn't his wife Lagertha, who appears unable to give him anymore children.
Acting upon the wishes of King Horik, Ragnar and a small party of his followers travel to Gotaland (modern day Sweden) to resolve a land dispute. While there, two of Ragnar's men, Arne and Torstein, stumble upon the beautiful and clever Aslaug. The men are reprimanded by a group of shield maidens, and Aslaug demands an apology from their Earl on their behalf.
Intrigued, Ragnar sees her as a challenge the gods have given him. Interested less in her beauty and more in her wit, Ragnar agrees to meet with her if she comes to them "neither dressed nor undressed, neither hungry nor full, and neither in company nor alone." Aslaug obliges, arriving dressed in a net, biting an onion, and with only a dog as a companion. Impressed by her ingenuity, Ragnar fulfills his end in the bargain and apologizes.
Smitten with each other, the two soon become lovers, much to the chagrin of his son Bjorn, who has travelled with his father and is intensely loyal to his mother. Short thereafter Aslaug tells Ragnar that she is carrying his child, and after asking Odin what he should do, he goes to visit her in her room. Bjorn almost stops him, but doesn't when he sees a raven in the window, which throughout the season has foretold the beginning of an important event.
Ragnar returns to Lagertha and admits his affair with Aslaug. Though clearly upset, Lagertha decides to set aside her anger. This changes, however, when the heavily pregnant Aslaug arrives in Kattegat. The two women, understandably, do not get along. Ragnar suggests that the he could be married to both Lagertha and Aslaug; Lagertha is insulted and, with Bjorn, decides to leave instead.
Four years after, Aslaug is living comfortably with Ragnar, having given birth to two sons, and pregnant with a third. Aslaug becomes suspicious when Ragnar starts a conversation with a new, young servant girl. Aslaug later warns the girl to be careful with whom she is familiar.
Later that night, Aslaug confronts Ragnar, claiming that he wants to sleep with the servant, amongst other women, which he denies. Aslaug then claims to be a völva. To convince Ragnar, she prophesizes that their next son will bear the image of the dragon Fafnir in his eye.
While Ragnar and his men raid England, Aslaug has given birth to a healthy son she named Sigurd Snake-in-the-Eye, after her father. As she had prophesized, the child bore the image of Fafnir in his eye.
Ragnar sets his sights on England once more and sets off to raid the country, leaving Aslaug to care for their children. While away, Jarl Borg invades Kattegat in revenge - Aslaug and her children, as well as Siggy and Rollo, manage to escape into the countryside. Aslaug is extremely unhappy about her new living conditions, saying the filth is bad for her children.
Word soon reaches Ragnar of Jarl Borg's invasion and he immediately heads back home, glad to find his wife safe. He is able to sneak into Kattegat with the help of Lagertha, who has brought both warriors and their son, Bjorn, and destroy their grain stores, thus pushing Jarl Borg out. Ragnar is thrilled to see his son again, but is conflicted about seeing Lagertha - he later tells the seer he wants both women. Lagertha, married to an Earl elsewhere, returns home, though her son remains in Kattegat. Aslaug and Lagertha exchange farewells and appear to harbor no resentment towards each other.
Not long after taking over Kattegat, Aslaug finds her self pregnant once more. She warned Ragnar not to force himself upon her for three days after his return or the child would be a monster. After a particularly difficult pregnancy and a birth that nearly killed both mother and child, Aslaug deliveries of a another son. As prophesied, the child is deformed.
Ragnar tells Aslaug that their son should be killed, as he won't live long with a deformity, though he is clearly upset at the thought. Aslaug refuses and although Ragnar steals the child away, he is unable to kill him. They name him Ivar, though others in the village are starting to whisper about the new child and what may be wrong with him.
- Aslaug's father, Sigurd the Dragonslayer, was a king of Gautland and a scion of the Volsung clan (descendants of Odin). And her mother was the shieldmaiden Brynhildr, daughter to King Budli of the Svear (Swedes). The Asmundar Saga mentions King Budli's ties with the Huns through his daughter Hildir's marriage to Helgi, son of Hildebrand.
- As of her husband Ragnar's successful coup against King Horik, Aslaug may be considered the Drottning (queen) of Denmark.
