Odds are that it will be someone who has influence or pull in the palace, that or they have the royals trust. I think it won't be a direct attack.
Or someone with a hella grudge.
Those types always seem unstoppable in these genres (￣∇￣")
Although I agree. I don’t think someone like that would be introduced so early into the storyline. Hopefully it’s someone underestimating and not someone with a heck of a grudge.
Hopefully. (⊙…⊙ )
three princes and an emperor good luck with that assassination idiot
