The Ebon Fortress is the fourth level of The Realm of Black Magic. It's a large and complex castle, composed of numerous corridors, some outdoor areas, Slime-filled moats, and a number of Flooded areas. This level can be very confusing and it is easy to get lost. Most of the fighting takes place in close proximity to the Player.

This level brings back the Rocket Launcher, as well as the Scrag if the player did not enter the level through E2M7. The player must search for the Silver Key in order to proceed, and can collect the Gold Key to get Yellow Armor and Nails.
