YES THE king is unless.
they want full control of them and they don't want them using the dragon's blessing/power...
...the forest is one of the dragon's blessing and i think it grants wish/prayers
(i think it's mentioned in the early chaps)
...as stated by the records left by their seniors it seems that yes they've been doing so from the previous kings to the little prince now, in the forest is where they kill the regas of the king now (the king is into blonde regas replacement because of that)(i think it was also mentioned that the duke? is also into blondes, maybe there is more into this sorry this is all i can recall)
Help me to recall
What is the villain’s end goal? To make the prince a puppet? What does it have to do with the forest? Why they tried so hard to make the forest a scary place? Did the current king also being manipulated?
