I do like the setting and story. I read it in my most mysterious and savage announcer voice and it sounded great! Also, the title is superb.
It looks like you meant for the sun-heir to also participate in the seeking. There's a little confusion for me in the third to last line of text. Additionally, and I'm sure this is up to the players, there's no clarity on how many rounds of trials should exist. The wording makes it sounds like one trial per player, but with three traits, there is no danger of losing anyone. I would suggest a complicated math of two rounds of trials per player, plus a further number of trials equal to half the number of players, rounded up (2x+1/2x). That guarantees at least more than one death. Haha!
