As we know according to the book, Maege is the Lady of Bear Island, with five daughters; Dacey, Alysane, Lyra, Jorelle, and Lyanna. Dacey dies at the Red Wedding, Alysane leaves with Ironborn, the whereabouts of Maege, Lyra, and Jorelle are unknown, even though they were together, while Lyanna was at home. Alysane is her mother's heir, and she has two children: a nine-year-old daughter and a two-year-old son.
So, the order of Bear Island heirs is:
- Maege
- Alysane
- her son
- her daughter
- Lyra
- Jorelle
- Lyanna
Lyanna and Alysanne's daughter are almost the same age, while Alysane's son is about seven years younger. The question is, what happens if Maege, Alysane, Lyra, and Jorelle all die in less than six years? Alysane's son would become Lord of Bear Island, and since he had not reached maturity (sixteen), he needed regent. However, in my case, the aunt (who would ideally be a regent) all that's left is Lyanna, who has also not reached maturity.
Who would be regent for him, considering all adult are dead? Or he just got advisors, like Bran when Robb went to war?
