I don't like your tone.

Well, excuse me, but what tone should I have towards someone so brazenly suggesting they gut me?

Seriously? Am I supposed to post in the thread about every single one of my "heroic" feats, like some people do?

Oh, right, it's better to pretend to be the smartest, organizing the peaceful players and supposedly searching for clues behind the scenes.

Alright, now about the suspicions.
I trust Tizetrium the most because of his deduction, but we can't rule out the possibility that he's a conspirator who exposed the murderer.
I somewhat trust His Majesty because he always spoke to the point and was clear.
I didn't trust Arisu initially – he acted in direct opposition to the king, only causing confusion. But now, my gut tells me that he's just a confused innocent.
I'm inclined to trust Ophelia because someone tried to kill her, and it was likely the conspirators.
Also, Ormhild – I haven't noticed any strange actions from her, and my gut feeling is the same.
Sir Gor and Lady Aravella... I distrust them more because of their lower activity; they might just be cautious conspirators.
Navirius also doesn't inspire confidence, especially because of his almost baseless vote to execute Amael.
And, of course, my dear Amael! I'll keep suspecting you until you finally explain the basis for suspecting me! And also, that performance of yours with Hasumi on the first day...

Cancel the autopsy of Amael, execute Navirius. Now, this seems more justified to me.
