This is a foolproof and highly untested world-building exercise where you only need a bathroom and some imagination. The more people you share the household with the better, since that will give you all sorts of strange artefacts (i.e. shampoo bottles) to get ideas from.
The idea is to just wander around aimlessly in the bathroom and use whatever is written on the bottles to give you a place, a magic item, a person, a villain, a whatever, and so on.
(I'm using the word "bottle" here very broadly; in reality, I mean any product you can find in your bathroom.)
If you're feeling hardcore you can use the relative locations of the bottles (products) to place them in your world, but that's really next level.
(I'm at home today with a cold so that may explain this idea.)
With that, let's head off to the loo...
-------------------------------------------
FOOT MENDER
A sturdy tower at the edge of a cliff, built in yellow bricks. A thick fog covers its top, dome-shaped. At night the dome pulsates with flashes of lights in a steady beat. There's always a wizard living here, whose sole purpose is to teach the spell of Foot Mend, which when cast will mend a creatures feet together into one for an hour.
MICELLAR
A hamlet home to so called "skin actives"; people that treats impurities using cloths and buckets of "holy water" (their words). After a treatment a person feel refreshed and clean, but is then chased out of the hamlet.
Afterwards, the used cloths and water is then thrown into an old well hidden away in the hamlet, home to the skin-devourer demon known as Micellar, from which the hamlet's got its name from.
GOMMAGE
A pillar of utter darkness, ten metres in diameter, that stretches from the ground high up into the air for as long as the eye can see. There's a faint smell of burnt-out bonfire. Anyone entering the darkness will have to endure 1d4 points of sandblasting damage for every round they remain there.
THE BODY SHOP
This is just three large carriages operated by three small, old women. They are non-practising necromancers that deal with body parts from a wide variation of different beings (all collected legally, of course). They keep these parts in glass jars, or, for larger pieces, in wooden barrels in their carriages. Regular customers include golem builders and eerie folks.
The women are very friendly, and strong, for some reason. If attacked, they will defend themselves using spells and bone saws.
EYE SHADOW QUARTET
A gang of thieves (if you can call four people a "gang"). They are known for their not so discrete method of throwing some kind of black powder in the face of their victims, which will cause immediate but temporary blindness, during which they steal whatever they can, before quickly disappearing. The victims are left with dark shadows and claw marks around their eyes.
It is believed that the black powder originates in some sort from GOMMAGE (see above), although it is not known how it is harvested.
SCULPTING WAX
Another small hamlet, named so because one of its locals - a young gentleman called Loreal Paris - can heal serious wounds and mend broken bones using an invention of his own: a sticky goo that the locals calls the sculpting wax. The wax is smeared upon and into the wound, no matter how large, and wrapped in linen, and after 1d4 nights the wound is healed.
His prices are pretty steep but the results are nearly always perfect.
No one knows where he gets the wax, and no one knows he's building a wax golem in a nearby cave.
