Queen Abigail Blackfyre née Lannister's last child, this time with her second husband, Osferth Hill.

Princess Scylla Blackfyre, The Two Tounged

Scylla Blackfyre

I've been meaning to make boards for all of Abigail's children and @omnipotent-scient kinda reminded me by mentioning Scylla so thank you!! (I tried to save this as a gif but it wouldn't lol)

Princess Scylla Blackfyre is the youngest of her siblings. She was born to Abigail Blackfyre and Osferth Hill, and by the time she came along her siblings were in their teens/adulthood. She preferred to stick to herself, studying history with special focuses on her favorite distant relatives like Visenya Targaryen, Tyanna of the Tower and Shiera Seastar, for most of her childhood despite having several friends. Her best friend however, Lynul Beesbury was not one to leave her be. The two of them were basically attached at the hip, when you saw one you saw the other. When they were in their mid teens they started sleeping together, they figured, why not? At 17 Scylla found out she was pregnant, both her and Lynul were every excited. They told Abigail and requested a marriage, which Abigail reluctantly agreed and after the wedding Scylla moved away to live at Honeyholt. Unfortunately for Scylla, Lynul wasn't near as good of a husband as he had been a friend. Scylla slowly started to resent him, especially after their son, Caspian, was born because Lynul immediately wanted another child even though he payed no mind to the one they had. Over the next year Scylla and Lynul grew distant, Caspian being the biggest point of argument between the two of them. On Caspian's first name day, Scylla had persuaded Lynul to host a hunt. All went well until Lynul fell off his horse, cracked open his scull on a rock and died. Scylla did not stay at Honeyholt after her husband's death, it's said she didn't wait a day to start packing. She took Caspian to The Red Keep to once again live with her family, at least those who still lived there. In a matter of months Scylla had found herself a new lover, Lord Enber Royce, who was aspiring to be a knight. After waiting less than a year the two of them wed and any and all could see they were happy with each other. Scylla and Enber decided to stay in The Red Keep and over the course of five years, they had three daughters, Jaehaera, Abigail and Naerys.

What are the fates of all of Abigail’s children? Also how is she related to Daemon Blackfyre (great great great granddaughter or?)

I haven't made ALL of her children yet but im pretty close so there are a couple names on this list that haven't been introduced yet and some are more developed than others but here we go! (I'll also put a little 🔥 next to the dragon riders)

Helaena 🔥 and Gannon 🔥 have an arranged marriage, Helaena becomes the queen and Gannon becomes the prince consort.

Daena 🔥 falls in love with and gets married to Darus Martell (Myrcella and Trystane's son) and becomes the princess of Dorne. (Myrcella lives because in this Oberyn is just blinded)

Piria is set to inherit The White Lion Company from Abigail so she mainly focuses on managing it while her mother rules, she marries Monterys Velaryon and moves to DriftMark at 26.

Jaron is the captain of the city watch when i introduce him to you all but be does eventually become the lord commander, he gets married to Ivona Brighthill (daughter of Eragon Hill so his 3rd cousin)

Loyna 🔥 is a dragon dreamer, she studies along side the Grand Maester of the Red Keep. In her 30's she marries a knight named Galleon Hightower.

Scylla (hasn't been introduced yet) has a marriage of convince to a lord named Lynul Beesbury, they have a son, Lynul dies a year after they get married in a hunting accident and Scylla returns to the Red Keep and immediately marries lord Enber Royce. The two of them remain in the Red Keep and have three daughters.

As for Abigail's relation to Daemon Blackfyre she is his great-something granddaughter through her grandmother.
