Jörðgarð Map of the Week #396 - Black Fortress Dungeon Juggeraut Trap - GM's Map

Map of the Week No. 396 is from the forthcoming Jörðgarð Trails adventure "A Tale of 2 Books." This week we see the game master's zoom view of the juggernaut trap on the second dungeon level. The arrrow shows the upward grade of the trap's floor.

  1. The Spiral Stairway from Level 1.

  2. The Pressure Plate.

  3. Portcullis Locations.

  4. The Catch.

  5. The Juggernaut Ball.

The metal plate in the floor is a trigger plate for the juggernaut trap. Once the pressure plate trigger is released, the two portcullis gates will fall from above. At the same time, one will hear a thundering sound to the left and from higher above. This is the sound of the juggernaut ball rolling.

The battlemap above is reduced in size. You can get the full-sized batlemap in two versions:

  1. The Fractal Mapper (TM) 8 version in FMP format (2 MB) from the Jörðgarð website.

  2. As a JPG flat map of 1360 x 910 Pixels (500 KB) available from the NBOS website at:


Both versions are released for personal and commercial use under the Open Game License Version 1.0a, which you can read on the Jörðgarð website at:
