Nah, Queens/Ladies are fine, so long as they're absolute. They need a clear line of succession, and as I said, they need to either get with another family member, themselves being the main ruler and the other just a Lord, yet not in real power, or matrilineally marry. Even bastards could join in, and solve this problem, ironically.

For Rhaenyra, that could even be Trevan Waters. A bastard, solemnly proclaimed by Rhaenyra to be a Blackfyre, marrying in, would lead to a Targaryen spawn. Or, just matrilineally marrying a minor noble, like literally a nobody, would work.

Shit, I might have given up a bit of your gig, haven't I?
