Well it’s basically what you expect from the name

Dream sans is a prisoner in the Royal Au,

Context is he’s a knight and got captured by the moon empire

You are a interrogator sent by nightmare to crack em to get the secrets and plans, or... you have sympathy for my bro, and yes you can bro :p

Any mistakes, point em out

Yes I also add in other details if I deem them good enough

Enjoy~
