Do you know the word "vengeful spirit"? This is not even 1/100 of it.
Thankfully, the spirits still have a peaceful mind so they didn't avenge the Royal Family yet.
Normally, the spirits will crush the whole Royal Family to dust.
(Change from power to money because real life doesn't have power)
Just thinking, in real life, if your family had "money", a poor person begged your family to give him some "money" to live.
Your ancestor refused him. He went and killed other members of your family to beg/rob for "money"
"Your killed family members" hate that man and tell the descendants to
avenge them by not to do any "business" with that man's family anymore. Eternally.
See? Too peaceful for Avengers.
And now what, that criminal's family is planning to kill anyone to beg you for "money" again.
Do you want to forgive them?
If anything, I think that young, innocent and pure prince might be the key to solve this.
