CONVERGENCE 20: THE DUNGEON CRAWLER’S BALL Halloween Night • October 31 • Historic Oddfellows Hall • Boulder NEW ACHIEVEMENT UNLOCKED: YOU’VE SURVIVED LONG ENOUGH TO PARTY. Congratulations, Crawler. Against all reasonable expectations, you’re still alive. Your reward? One night inside The Dungeon Crawler’s Ball—a Halloween descent into electronic music, live bands, strange creatures, questionable decisions, pounding bass, and several hundred people dressed as if civilization has already collapsed. On October 31st, the Historic Oddfellows Hall transforms into a multi-level dungeon where DJs, electronic artists, and live musicians battle for control of the sound system while Crawlers, monsters, royalty, assassins, aliens, gods, demons, and whatever the hell you came dressed as take over the dance floor. Expect deep bass. Live instrumentation. Electronic mayhem. Lights. Costumes. Dancing. Hidden surprises. And the increasingly strong possibility that nobody bothered to read the dungeon rules. SYSTEM ANNOUNCEMENT: Costumes are strongly encouraged. Actually, forget that. Costumes are practically mandatory. This is Level 20. Show some commitment. Come as a Crawler. Come as a boss monster. Come as something beautiful, terrifying, ridiculous, or completely inexplicable. Just remember: the Dungeon rewards creativity. And yes, there will be consequences.
