The Underearth is the seventh and Secret Level of The Realm of Black Magic. The exit is very close to the start, yet players will have to "go for a swim" in the nearby River first. An underwater passage leads to the rest of the level. It's composed of many types of areas - moss-covered caverns, castle-like hallways, and dark crypt-like passages. Numerous Slime pits threaten the unwary and there are a few more unusual traps as well such as Nail Traps.

This level brings back Scrags. The player must search for the Gold Key in order to proceed. This is the hardest level of the Realm of Black Magic, as there is a great amount of enemies and a lesser number of supplies, like the later episodes will have.

The level contains another Easter Egg - a hidden room with a logo and the initials of Tim Willits and Theresa Chasar in it.

At 11 spawn points, E2M7 has the most out of any vanilla level.

When all the Buttons are pushed, exit through the newly unlocked Door to the left. Collect a 15 Health and 25 Health to the left in the next hallway, and a 25 Health, Shells, and Nails to the right.

The final alcove has nothing besides a Button, which the opposite alcove has as well to unlock the Bars leading to the exit room, the Arch will be Unbarred as well.

Also in this level is an Easter Egg opened by shooting all the gargoyle walls in the level. After it is shot, go to the second sunken wall in the sunken wall room and shoot the Wall. Inside is just a symbol of a raven based on the maps of Tim Willits and Theresa Chasar for Doom. The initials of them are located below the symbol. The Gargoyles' locations are noted below:
