I kept it vague because I wanted it to be flexible. How about a male and a female dragoness, each with their own lairs, servants, and territory. Each territory would have tribute-paying subjects, and although the dragon and dragoness would become mates, this would not be a straight-up romance. Rather, it would be as much a political matter as a matter of love, as it would require that both territories be merged into one realm.
I can play the dragoness if you want.
