If she dies the contry dies with her cause of lucas(⊙…⊙ ) Whit gun
But would Lucas destroy the country when he is the on that showed the branch of world tree, it is mostly his fault. But if she dies because of the shitty noble of the empire it will be obliterated.
He probably would cause it true it's because he showed her the world tree,but it's all because of the noble he might lose control of hes emotion and go on a rampage if you see what i meen
I'm telling you, if the princess dies for the emperor to be healed, I will haunt the writer of this manhwa.
