In general, the World Building tag captures all of these posts and more.
Economy
Not much work done here yet. I reviewed an excellent gaming supplement that tackles the issue and I may use a similar approach as my foundation.
Fantasy Races
Each post detailing the standard races has some lore in it about their place in the world. I'm proud of the post on Elves and plan on going back to change all the lore to be more dynamic and less generic.
- Kobolds are house spirits that inhabit the homes of those who hold onto pagan believes.
- Goblin tribes form a dying race of raiding nomads living on the fringe of the Empire.
- Orc Khans once ravaged their way through Asia and Europe, but now mostly exist as a legacy of Khanates and Half-Orcs.

Religion
Fertile ground here, I have only broken that ground with a discussion on divine casters and raise dead in the 17th century, plus some very cursory thoughts about the cosmos and deities.
