There is a megadungeon beneath the Magic City of Booezor that stretches down through the Sculpted Mountain and deep into the earth below. It is unknown for how many levels the structure continues underground, but there are six entry points and each is a dungeon of its own: a giant magnetic termite mound, the sewer system, the tomb of the mountain's heart, the magically accelerated dumping grounds, the moonmetal mine, and the partially physical prison space the Labrynthyne.
Booezor is divided into eight "tiers", the first three are accessible to anyone (like 1st level PCs), while the other five are unlocked by amassing wealth or otherwise raising your social station:
The Weave, a hanging shantytown and scattered caves hung from the side of the sculpted mountain, difficult to get to, many entrances exist not considered part of the city proper.
Bottomshelf / Beastmile, lower cliff villages each with their own name, difficult to get to, many entrances exist, not considered part of the city proper, and the city's external animal market, a town in itself.
Fruitbasket / Waspnest / the Sprawl, the lowest main level of the city, street after street of markets, shops, residences, taverns, lodging, and assorted frantic industry.
Secondmarket / Cindiband, the higher classed and more specialized markets and shops are here, the residences higher, the entertainment more elaborate.
Lighttown, high class everything, hotels, night life, gambling, street noble culture, everyone wears disposable magic light junk and revels in excess.
Stoneforest, bridge-connected highspires house the super-rich, the mage elite, and their clustered entertainments.
Precious Pillars, the highest and most improbable towers belong to the most venerable Children, unaligned magi, and the ultra-rich (1%).
The Egg, a permanent physical extrusion, made of pure magic, of a vast extradimensional space that serves as the campus of the Children. Truly there is a palace within the space the Egg describes.
So I need to continue to work on Booezor enough to comfortably run it without getting completely carried away. A bunch of boring work is done, tentative tables of item, armor, and weapon prices and which tiers of the city they are available in. Started a table for animal prices. Got an easy d100 table of types of buildings in the city. And I am waist deep in a d100 table of city rumors and another of specific NPCs, which are super cool. Oh, and this fun motivation table:
d20 Reasons to Seek the Depths
1 you seek an ancestor's spirit trapped within a soul crystal you will know by touch, such crystals were popular in ages past, and are found in the deeper areas.
2 you seek to confront a specific powerful undead creature, whom you have a (personal) connection to, and who lairs in the deepest depths.
3 you seek the water at the source of the Haelix, one of the twin rivers that flow beneath the city, whose current flows in an upward spiral.
4 you seek the land of the subterranean sea fed by the mouth of the Xeeres, one of the twin rivers that flow beneath the city, whose current flows in a downward spiral.
5 you seek to recapture seven unbound demons, who have installed themselves as lords of the deeper dungeon.
6 you seek access to the insane civilizations and beings of the 'Veins of the Earth', which can be found through the lowest levels of the megadungeon.
