During a festival, a mysterious dancing curse struck Stormhaven. People afflicted would dance until they collapsed from exhaustion and eventually died. The curse could spread from person to person, and the city was placed under lockdown.
After a number of days, a group of adventurers managed to track down and confront the person responsible, a pink tiefling bard by the name of Twinkletoes. She challenged the group to a dance-off, but when one of their number (a halfling named Magda) bested her, she erupted in a rage and a fight broke out. Another bard, an elf named Dorian Merrick, showed up partway through and managed to talk her down. Subsequently, she was hauled off in chains by the city guard.
