Nearly all the bars in Velaris have “NO SERVICE TO” posters of Cassian because of how overwhelmingly drunk he’d get during those 50 years the Inner Circle was stuck there knowing what was happening to Rhysand.
Not because he is a violent drunk-
-because he’d hang on as many patrons at once as possible, wailing with booze in hand about how amazing and perfect their High Lord was, shouting “DO YOU KNOW WHAT THAT GLORIOUS BASTARD IS DOING RIGHT NOW FOR ALL OF US?!” as snot and tears drip all over the place.
After Rhysand came back, those first couple days where you KNOW he didn’t leave the house and had to be surrounded by his friends, Cassian stole away to quietly threaten the lives of every single barkeep and patron he could find.
If they didn’t tell Rhys the posters were because he was “too much fun when drunk” or “conquered too many beautiful females with his amazing charm”, he’d bring his own little slice of the Court of Nightmares to Velaris just for them.
As he left each establishment, Azriel faded in from the shadows to bribe them like a CIVILIZED Illyrian.
