Dorian's a smidge easier to find. He keeps a place to return to when he's between victims and such. The mail often piles up since he's not there regularly, but he still gets his invitation there. Maybe if Sivan mentions it to him, Dorian can make a mental note to let his friend and mentor know whenever he's aware of something going on that might interest Sivan.

He wouldn't say he's friends with many of the guests. He knows a handful from simply being around. He's friendly enough with most, but he's not really interested in most people if he can't make a plaything of them at some point. Maybe that's just his nature as a demon. He's also dressed primarily in black, the blazer of his suit embroidered with a golden sun on one shoulder and on the opposite hip. He's grabbing some refreshment when he spots a familiar face among the other guests and positively ignites. He quickly grabs a second glass of champagne and scampers over, all eagerness and smiles.

"Well, well, well! The Great and Amazing Sivan graces us with his presence," he declares as he hands the drink to him.
