You decide to accept Sun-nut's compromise.
6.8 CS:
A very solemn looking Cherub enters your court and bows low.
"My queen," he states, "I come bearing terrible news. Your son Uzru has been slain!"
"What! How?"
"We are unsure. We just recieved the messenger from Bark-Ark's seat of judgement bearing the news. Your son's soul showed up at his seat two days ago. He cannot recall the manner of his death, but guesses that he was murdered in his sleep; He was rooming in a hostel with a dozen other mercenaries, heroes, and adventurers sent to kill Green Oni Midoriiro as he was. It was likely somebody struck him down to thin out the competition." The Cherub explains.
"And what judgement has Bark-Ark passed on my son's soul?" You ask.
"He has sentenced Uzru to angel training at the Amber Palace, should you consent to taking him back of course."
You sigh. Not only do you have to figure out what to do with your son's soul, but you also have to decide if his death merits further investigation.
As for his soul...
A: Of course I will have it back. I do not abandon family.
B: Moonpetal will not want her failure of a husband returned to her. I decline.
As for his death...
A: He died on Kappa lands, so the responsibility to investigate falls to Ikarinojoō, the mortal queen of Kappa.
B: He died on Kappa lands, so the responsibility to investigate falls to the Abysall Gods worshiped there.
C: I have a spymaster who is also an Abyssal Diety by birth. I will pull Lahara from the case of the missing staff, and put her on this!
D: I have a consort who is also a Kappa! Old age shall not stop Senshinochi from returning to his homeland to investigate the death of his son!
F: I have better things to be doing than worrying about the murder of a mortal.
