I dunno...Sorrow kinda IS Fear, though. A lot of the King of Sorrow's actions were done in the FEAR of being forgotten...
Nah, I don't think fear and sorrow are the same at all. Lolo was from the Kingdom of Tranquility and felt sorrow, does that make those the same? (I'm not trying to tear you down btw)
The King's actions were a mix of frustration, bitterness, fear and sorrow if you ask me. But I'm talking like..the Kingdom of Unmitigated-Existential-Terror, here. Citizens are afraid to leave their homes because of what might
happen. They're distrusting, jumpy, irrational, anxiety-prone messes and it's a wonder how their society even functions. Whether or not there would be something to actually fear in this kingdom I dunno, I haven't thought that far.
