E2M6: The Dismal Oubliette

The Dismal Oubliette is the sixth and final level of The Realm of Black Magic. The level is divided into four parts, accessible from a central bridge above a pit of Water. After leaving the small starting area, players encounter a small fortress-like structure built entirely underground (shown in the screenshot). The third area of the Oubliette is a multi-story tower with several rooms on each floor and an Elevator perpetually moving between them. The final area is a slow Elevator descent into a deep shaft, leading the player towards the final confrontation against a Vore and the second Rune.

It is second map to contain a Rune. In this level the player must collect the Gold Key and the Rune. This level introduces the Vore as a boss guarding the Rune. On normal and higher skills, there are 2 Vores at the end. As the Vore later becomes a regular enemy, it is made to be like the introduction of the Baron of Hell in Doom. The map is made around a central bridge in the center of the map, which must be changed a couple of times to get to the slow moving Elevator leading to the Rune.

Jump into the Water and go to the right under the platform you were on to find a small room  (#1) .

Drop into the room at the end to get to the window of the right tower while collecting the Rockets and pushing the Pillar changing the platform setup of the center bridge. A Wall shall open to the right to allow you to return to the second floor platform of the right tower. A Wall has opened up on this platform to the right to a new passageway. Collect a 25 Health and go up the stairs to the right. At the top collect the Shells and Nails, and kill the Zombie. Follow the signpost to the right to drop to the ground overlooking the two towers. Return to the center bridge.

Take the straight way from the starting position, which cannot be returned to as the position of the bridge has shifted, of the center bridge. Collect the Yellow Armor and kill the Death Knight to the right, as well as collect the Nails to the right. The Door is locked, so follow the left passageway down the stairs to the right to an Ogre and an Elevator with a signpost showing the way to the Gold Key. At the bottom turn to the right and collect the Shells and Nails. Take the left or right passageway and collect the two 25 Health, one for each side, and kill the Death Knight that patrols this room.

Collect a 100 Health, Nails, and Rockets by the column in the middle of the room, and kill the Zombie. Collect the Cells on the far side by the column, and the room will lock you in with a Fiend. As the room descends, it will get to an area with 4 Nail Traps on the column, and a Fiend will spawn in. A little later 2 Zombies will spawn in. Eventually the Elevator will stop. Go to the far wall from where you entered the Elevator and the Wall will move, revealing the room with the Rune. It is however guarded by a Vore, the boss of The Realm of Black Magic.

Differences in Quake 64

 * 2) Frames around the central hub's archways were removed, making rocketjumping across the gaps easier.

Trivia

 * This map originally had a large, watery cavernous area before what is now the starting room: an actual oubliette. According to John Romero, this was removed because the final compiled map was too large to fit onto a floppy disk (presumably for ease of transfer during development). This area was later released as E2M10: Lost Entrance of the Dismal Oubliette.
 * In the enhanced version, this part of the original map was implemented into the level.
 * John Romero considers the corridors around the Elevator leading to the Gold Key to be a good example of his perception being off in terms of visual space due to the differences of Quake and Doom. This caused those corridors to be very cramped and dangerous. Even upon release, he knew the scale was incorrect but didn't have the time to fix it.
