The Great Realm needs you! Yes you!
The Great Realm's conquests are going to be in need of a lot of dungeons and ideas for them. A dungeon can mean an actual dungeon or a crypt or a tree top village, etc. You can be as detailed or vague as you like offering a simple one sentence idea or a paragraph including back story and named bosses. I've always tried my best to include the players in the development of Pit of War, so if you are so inclined why don't you see what you can come up with! Try and keep things in the theme of the game using the game's races etc.
Good luck in the Pit!
