Local boy runs up to you, tells you the news, demands you pay him two coppers for info.
 Group of rambunctious youths are gathering all their friends together.
 The crowd is so loud you can hear it from a street and a half over.
 Town guard telling people to stay back- they don't want to make it even more chaotic.
 Local wizard has ensorcelled several parrots made of paper to life. They squawk the news.
 Stray dogs run from the butcher's stalls with bones in their mouth. Nobody is chasing them- that's odd. Better go see what that's about.
What's the atmosphere of the crowd surrounding it?
 Concerned, whispering. What will the neighboring town think?
 Violent, bloodthirsty. Angry mob may be forming- they throw stones.
 Depressed, almost sad. How could this happen here? The elders shake their heads.
 Jovial, festival like. People are trying to sell snacks and crates to stand on for a better view.
 Angry, accusing. They're piling up the shame on people; somebody is going to get exiled.
 Casual, giggly enjoyment. People are laughing- this is hilarious. Like gossiping schoolgirls. If you see someone prim and proper joining in, they'll be embarrassed afterwards.
Who or What is the primary target of all this hubbub?
 Some weird, smoking rock that fell from space
 It's a goblin or little orc boy- he was found hiding under a fruit cart. Verge of tears.
 It's a parchment nailed to a wall. On it are outrageous laws and their exorbitant fines.
 Fat little merchant is panicking- he dropped a padded case which contained the King's sword. Now it has a tiny nick in the blade and he's desperately trying to find the little piece in the gutters.
 Young girl pulled the magic wand out from a magician's sleeve- they're supposed to use slight of hand, not actual magic! That's cheating! He's desperately trying to persuade her to return it.
 Snooty shrew of a woman is throwing down her lover's pearl necklace and crushing them under her heels- while he is right there trying to get her to stop and keep her voice down.
What big official has to come and stick their nose in it?
 It's the Prince! He's observing silently, rubbing his peach fuzz in thought.
 Richest local merchant, tries very hard to act like he's one of the “common people”.
 Leader of the Mage's Hall. Offers to amend situation with magic, WILL fuck it up.
 Wise man or respected elder. They say something vague and mildly prophetic.
 Captain of the Guard. Screeches about violations. No loitering! No crowding! No gossiping! No having this-much-fun without a license!
 Priest from the local temple. Swings around a holy symbol accusing everyone of sinning, even if he was caught up with the crowd of a moment ago.
(Optional) How does the party get roped into this?
 Hey you're a bunch of adventurers right? Go “adventure” this problem away.
 Whatever is going on is somehow involved in your main quest.
 The big official has it out for you. He instantly accuses you all of involvement.
 Superstitious townsfolk blame outsiders like you for the trouble.
 The target is somehow related to the past or recent events of one of the characters.
 Some very contrived reason- your birthmark happens to match the cobblestones right under the feet of this event. Everyone shrieks about faith for a second as you roll your eyes.
