FYI, anyone worried about background length does NOT need to follow my example (I just like to write). However, you're welcome to look at it and even get ideas from it. Just keep in mind you don't know it
Also, several of the things I touched on were from the first game.
A few I can remember:
There is at least one small comunity of sewer farmers, likely several throught the sewer. There are also legends of a rather large dire rat patrolling the sewers and protecting the farmers.
The Apartments is a HUGE complex of rooms, places to live, offices, places of business, etc. Large enough to have it's own underworld (several in fact), and at least one minor government.
I'm not sure if they are still around, but there is at least one religion that uses the undead to farm, which solves the problem of what to do with the dead. However, since people actualy started dying and staying dead again, this may have subsided.
There are several newspapers in circulation in the city, depending on where you are.
There is a canal system on the surface over parts of the city.
There are Numerous underworld organizations, as well as numerous noble houses (or those who call themselves nobles at least).
One result from the first game:
The Church of the Heart
A church celebrating the sacrifice of a brave soul long ago, who gave his heart to the city. It is said his lifeblood pumps through the sewers, and his spirit wanders them and watches over the people.
The church strives to do good by the city, tending to those it can, offering it's services to the needy, and runs many orphanages.

There's another church of the God of Death, but you'd have to ask Fernis to write it up.
