510 AD, Summer
You look at the gathering of elderly men that appeared in your chamber alongside the Advisor. They look very fidgety and they have grimaces darkening their faces. You rarely see these three, and even more rarely you speak with them, as they spend time with your children, instead at the court. Them showing up like this is quite foreboding.
"Yes?" You ask, placing your hands on the desk.
"My liege, don't take it personally, or, Creator forbid, hold what we want to say against your family." Says the man who is teaching your kids language.
"But we believe that there's slight problem with your eldest son and heir to the throne, Len. He has, ah, slight trouble learning new things, and remembering what he has learned so far." Says the man who is teaching your kids heraldry and religion.
"Younger children of other noblemen are already more focused, smarter and learned than Len is, which, well, does not put him in good light as an heir..." Says the man who is teaching your kids numbers and laws.
They look at each other, and then at the Advisor, who steps closer.
"My liege, my esteemed colleagues wanted to say that your son, Len, is
dim-witted, and will not make a fine King." The Advisor puts it bluntly for you, stroking his beard.
A) "Surely you can find some other quality about him! Go ask others for their help to find it. And you better find it, and fast!"
B) "A failure like that will not rule the Kingdom. Prepare the parchment! Len is no longer my son and heir!"
C) "This is the first and last time we're talking about it. Len is my heir, and that is set in laws! Begone!!"
D) "Call for Archdruid. We need the spirits and the Creator to lift the fog from my son's mind!"
