I have currently run 5 ongoing campaigns:
  • The Lighthouse o'er Brotheldeep
  • The Forsaken City
  • The Gloamwood Job
  • Wild West Water Shortage
  • Shipwrecked!
and several 1-shots.

Technically, they have all taken place in the same world:

Ker'ether

My world, to allow the greatest possible diversity, generally includes all material from the Forgotten Realms Campaign Setting, Dragonlance Campaign Setting, and Eberron Campaign Setting. This means that there are many wild places in the world where terrifying evil can be found alongside both newly destroyed and long-lost ruins, but also that the civilized cities have had the time and stability to advance to the more magically modernized setting exemplified by Eberron.
I have listed generally interesting and useful options for my campaign here, to highlight the most unique ones. Much more information about my world can be found on the Ker'ether page, linked above.

Specifically Utilized Gods:
While you can request to serve almost any deity in any published D&D material (or otherwise, I like gods), these are ones I have specifically used in Campaigns, meaning there may be some support for these deities already within the world.
Three deities have the designation of "Reaper," which means they are the gods who specifically collect the souls of those who die. What happens to those souls, where they ultimately reside and the cost of a benevolent end, depends on the Reaper and the soul's bargaining power (and that of its deific patrons).
