A one shot that referenced the game world, but players who played in both the one shot and the sustained campaign have asked it to be table canon.  So, Abandominiom, a world that is a literally broken world, in that over a hemisphere of it has fragmented and trail the more intact portion a la a rogue comet with little real world astrophysics informing the phenomenon, is held to together proverbially by the abdicator's once Left Hand Being, a Mapach (from Humblewood) named Vidal, who has taken on the mantle of Sergeant Regent.  Little did the Loyalist Remnant, or Vidal himself, realize that Vidal's jazzy woodwind playing was in fact literally instrumental in keeping the rogue comet into some sort of harmonic line.  That is until a Amethyst Gem dragon had the instrument seized as the comet sped in proximity to a rift into the Far Realm, because the dragon was curious what the implication would be of a mortal world transmitting such a rift.  During the approach many were plagued by nightmares, their unconscious perception foretelling but not comprehending a pending breach beyond prime material reality.  Adventurers of lineages rooted in dreamlands were mustered to intervene and battled fiend and far realm over layers of illusory dreamscape to secure the instrument (who during this period of urgency would spontaneously issue "BRAAAM"s that seemed beyond its realistic musical capacities, the blasts hearkening to a layer of dream deception being broken, though each breach was concurrent with more disastrous spiraling of the unstable comet.  Victory was achieved, the dream adventurers made their way past the abandoned capital that had hidden the instrument, through the parking lot, into the desert to the reclaimed watering hole that the Loyalist Remnant used as a bivouac, the instrument restored to its rightful owner, a performance was played that righted the world to a degree avoiding utter catastrophe.

In short the world was saved when a bassoon was restored to a raccoon who played it by a saloon amidst the dunes.  And yes, Vidal's last name is Sassoon. 

The one game I actually ran was a goofy one-shot which revolved around a group of adventurers hired to protect a castle from an army of orcs that was launching a full-blown siege over a j-walking incident. I've since thrown around the idea that orcs in this world are fanatically obsessed with road safety, to the point where they have extreme punishments for the slightest violations. Things like getting burned at the stake for running a red light, thrown in the stocks and pelted with rotten vegetables for not looking both ways before you cross the street, drawn and quartered for speeding. Maybe having the roads line with gibbet cages containing decomposing skeletal remains with a sign saying something along the lines of "j-walkers ye be warned!"

What do they do to people who turn without signalling?

One of my scrapped worlds that I never got to run had, as part of an incredibly obnoxious pun, recreational drug use as a prominent aspect of high elf culture.

They get put on the rack.

They get whichever arm they didn't signal with stretched, to remind them in future!

 This is honestly the best one here.

So Kayda, my dragonborn, has a pet glow-in-the-dark slug, she asked her warlock friend to poly morph (or wild shift, i can't remember) the slug into a crab. Kayda proceeded to teach the crab how to do the crab rave and showed the rest of the part.

The Chorzhoi Orcs of the Middlemarches are one of the most dreaded enemies of the Cardendan Empire, not because of their ferocity or skill at arms, although they have all that to spare.  It’s because of their gift for satire.

After they defeat you on the field, they lampoon you in comedic verse.  Their bards have a gift for deft wordplay and hooks for days.  Not every song they write is a banger, but every one is a toe-tapper.  And every general in Castelrouge knows the experience of hearing a song about their worst failure sung innocently by children on the street at least once in their life.  The Chorzoi call this K’tom Lyev, The Final Knife.

Vecna blew up the moon

I Am frightening TBH

I have one eyed, one horned, flying purple people eaters who can be befriended by playing rock n roll music.

I have two different magical items that grant the ability to create and webbing that is essentially Spider-Man based stuff.

One of the most powerful beings is a Warforged-like construct that appears to be a young girl in a maid outfit.

One of the beings who visited the world from one of the other dimensions in ages long past made a huge name for himself before he was discovered in what became a huge scandal. his name was Lepre the Kaun (the people are Kauns), and ever since then all of them are called…

 A good third of my world’s lore is references to in-jokes, movies, films, and books that went into he inspiration of it, even though it is very much nothing like any of them. And when we play, I will take silly things and run with them, playing the straight.

In my group's campaign, we have a goblin named Barrel that was born in a barrel and it doesn't know how to read anything but tavern menus.

A pirate utopia / secret haven. An evolved version of plutocracy called bootycracy, where you get more votes if you donate more booty to the town. Value for different types of booty is set yearly by the elected Booty Council. Registers for voting rights and booty donations are maintained by the Secretary of Booty, commonly known as the Bootytary. 😄

I have too much wacky stuff to include here but here are a few:

There is a god of buckets who wants everyone in the world to stick their head in a tin can.

The demon lord of chaos is a bumblebee.

There is a "god" of everything that starts with the letter B.

Aaracokra and other bird folk are ravaged by a disease called Chicken Pox that turns them into chickens.

Yo-yo's were invented in the land of the dead because it is really boring down there. 

When you die the Grim Sweeper comes for your soul. He sweeps away your spirit with his broom.

Mimic-sharks exist. They are mimics that resemble sharks and when you get close to them they eat you. Surprise! I bet you weren't expecting that!

The god of life is a porpoise. This is a pun on the purpose of life. 

Just spotted another one: I have "Towel" in my equipment lists.

Folks who buy it always say that they are ready. The younger folks look at them like they are nuts -- and then buy a towel.

Edited: found another one, referencing the way life after death works:

In rare or unusual circumstances, someone may be summoned or incarnated from outside the Cycle, outside the Cosmos. They are Incarnates, and are considered uniformly weird, but they, too, are subject to the Cycle thereafter. Antelle calls it the “hotel kalifornya” complex.

On one of the three continents, there's a region where the economy is dependent on the herding of fire-breathing...

Sheep.

Their meat is universally (across the continent, at least) considered one of the finest delicacies there is.

Another found, this time in my older "house rules" spells. Lordy, we had to have made this back in like '02, '03, lol.

That's at least how long the Towel has been in the equipment lists.

Conjure Towel

Level:	1	Complexity:	Simple	School:	Evocation	Cast Time:	1	Attack:	--
Duration:	0	Range:	Self	Area:	Self	Effect:	Towel	Save:	--
Space:	20'	Time:	2 hours	Circle:	5'			Targets:	--

You create a white, cotton terrycloth towel measuring 2 feet wide and 3 feet long, weighing 1.5 pounds.

You are now ready.

That's it. That's the whole spell. Ignore the odd structure, please, lol. It references some rules for rituals and such for the new game.

I'm beginning to think that AEDorsay is one hoopy frood.
