Bryllon is the ship of IDKHBTFM's Dallon Weekes Panic! At The Disco's current member Mr. Disco.....I mean Brendon Urie and Panic! At The Disco's previous member Ryan Ross.

This ship is 100% fictional because Ryan and Dallon have never met and Dallon was married three years before he joined Panic! as a touring member in 2008.

To summarize:
Bryllon is a fictional relationship between Brendon Boyd Urie, Dallon James Weekes, and George Ryan Ross III

No photos could be found but there is some fanart on hesitant-vampire's tumblr but they specifically ask not to repost without permission and this was a joke book so I'm not gonna go through with that much effort. Sorry.
