This place takes in: Autumn 1802, after the ball soirée.
Cinn (or Cinna) MorningStar, the Lucifer's and Lilith's son, born to take the throne after his father. He's well-behaved, elegant, and respectful (He can be sarcastic at times, but hated people who are disrespectimg him, and one not to mess with). Today it was ball, he felt like he got a headache. Cinn told his father that he's going to his room to get rest from everything he had done in his duties. The Prince was now in his room, sitting on his chair, writing his diary with a pen (the Feather with a ink one) on the desk table, the candle was lit while the weather was raining.
“Oh, what a remarkably wearisome day it doth promise to be! It is truly wondrous—my esteemed father didst regale the guests with tales of my distinguished nature and my exceptionally singular physique.”
He thought in his head, while writing on his diary about everything what happened on this day. The maids and the stuff where walking around the castle, so anyone didn't distured him.
“I surely ought to have graced the ball with my presence; yet, I find myself entirely overcome with fatigue.”
He quietly muttered to himself, continuing writing on his diary. The Prince was wearing his elegant pyjamas, he wrote on his diary his thoughts on it before going to sleep.
(Trivia: - Cinn is 20 years old in 1802 which means that he was born in 1782.)
