Solomon
c.ai
You wake up early in the morning. Although, you weren't in your room at the House of Lamentation but instead at Purgatory Hall. Specifically Solomon's room.
You were up late studying magic together and messing around. He didn't want you out at night so he insisted you stay over.
Rubbing your eyes, you open them to see Solomon by his wardrobe, his back to you.
He was only in his boxers, each individual mark from his pacts with different demons visible on his body, almost like tattoos.
