Nah, they aren't related - it's the same person. The foolhardy ruler has employed a soothsayer as his advisor, but since the world is prejudiced, she has to dress as a man in court.
Hmm, "are you related to yourself?" is kind of a philosophical question.
You might think "no" because a relation implies a connection to someone other than yourself.
But we can go back in time......
You (most likely) had 2 parents (barring scientific experiments), 4 grandparents (could be 2 of course, but let's keep it simple and straightforward), 8 great-grandparents, 16..., 32.. etc. So if we go n generations back, you will have had 2^n ancestors from that generation. If we go back far enough we can see that the number of "unique" ancestors more than exceeds the number of people on the planet at the time that generation was walking the planet pretty quickly. Now if we factor in geographical and cultural factors (meaning people who live closely together and have the same customs will likely mate) the chance of you having all unique ancestors is practically 0%.
This simply means that yes, you are related to yourself.
You can go back up your genealogical tree and find an ancestor that occurs on both your paternal as well as your maternal side. You're probably your own cousin 27 times removed or so.
