Something I've been pondering is, what if during the year long marriage between the Phoenix King and Everqueen of Ulthuan, their only child, or children were sons? While the Phoenix King is an elective title, the Everqueen is a hereditary one from mother to daughter.
So, if the only children the Phoenix King and Everqueen had were sons, who would be the next Everqueen? I can see two likely scenarios.
The next Everqueen is the wife of the Phoenix King and Everqueen's eldest son.
The next Everqueen is then daughter of the Everqueen'sm consort AFTER her marriage with the Phoenix King.
Which do you think is more likely? What do YOU think would happen?
