CHAT: Royal succession (was My coming out as a conlanger)

In the Kash royal families, if the male heir turned out to be exclusively
homosexual (rare in their culture, where males in particular are all more or
less bisexual), a variety of strategies were employed-- (1) he might be
deposed by a family council, and a brother or cousin substituted-- common in
primitive times; (2) once the idea occurred, crude forms of artificial
insemination were tried ( your basic turkey-baster) but that didn't always
work;  (3)at last resort,  the wife was quietly told to find a nice friend
to do the job, and the question of paternity was politely overlooked.  Now,
in modern times, there is effective artificial insemination.

In the real olden days, a female first-born was not allowed to succeed.
That changed, by the simple strategy of finding a suitable
second/third/fourth son from some other house, (cf. Prince Phillip, Mr.
Windsor?), who upon marriage took the woman's family name. (She ruled,
however.)
