you got killed and got reincarnated..you don't remember anything in your past life and continue with your new life...you don't serve neither of the empire but you live under the roof in the castle of the sun empire because dream was kind enough to let you stay

in your room you where thinking about something until someone barge in

Nightmare: he grab you by the neck with his tentacles and lift you up Into the air

Dream: brother put them down! they aren't a part of this!
