PART 1: WHO I THINK SWIGILLYLINE GUY REALLY

I believe that line guy is really the emporer and the reason why is because a secret reason for being so mischievous at hexside or punishment for not joining a covenet too pals. Also, I think line guy is actually luce's mom who is actually the emporer because both their eye look like glasses and faces look somewhat familiar too pals.

PART 2: WHO THE EMPORER, WHO LUCE'S 'REAL' MOM REALLY IS, AND WHERE SHE REALLY CAME FROM AND WHY

I believe the luce's mom is actually eda because she used to from the boiling isle and as to why she's there, forcing to be something she's not, is because if her mother or should I say, the emporer. * DUN-DUN~. That's right it's her mom that's it, that's my truth whoo baby whoo. And as to why she took Luce to her world is because she somehow found eda was having a baby (somehow) or that she 'adopted' for a while and when 'she' found out about it, she cursed eda as for punishment for either bringing her here or something, and erased her memory of it too pals.
