Each Material Plane has its own Shadow Plane, a shadow of the world it is connected to. This article is about the known monsters of the Shadow Plane connected to the The World aka "Third Material Plane" (3MP).

While Demons from the Demon Homeworld have come to inhabit the 3MP's Shadow Plane, they are not native to this Plane, and not the subject of this article. Those demons who do live on this place do develop shadowy traits that are unusual for their species, theorised to be caused by their diet.

Blood Mist[]

Crimson Death 2e

Crimson Death 2e from the AD&D 2nd Edition Monstrous Compendium Forgotten Realms Appendix

Blood Mist, also known as vampiric mist, crimson mist, or crimson death, is a malevolent, vaporous creature that feeds on the bodily fluids of its victims.

The body of the crimson death is a cloud of pale color. It is difficult to distinguish if seen against fog and nearly invisible to infravision. When the creature is fed, it develops a crimson flush that is easily visible by normal or infravision.

The crimson death is a secretive creature. It prefers to feed on solitary beings, since these are easy to sneak up on and have no allies to lend them support. If several people are present, the crimson death tries to pick off the guard while the others sleep; it then feeds on the others at its leisure.

(Could also be based on the Scarlet Dancer Mist, which is like the Crimson Death, except doesn't have the intelligence or humanoid appearance).


Chomper - Lichbrush

Chomper by Lichbrush

Also known as a Vombat. "You can see these bizarrely shaped creatures. They are black oval shaped (like a football) with large leathery bat wings on either side. Where there ought to be a face is an open maw with sharp pointy teeth, no eyes, very little to a body anywhere." Fuzzy skin. (Hardcore Heroes Otherside: Episode 2)

Chompers do not seem to have organised attacks, will attack anything that comes into its path and will not coordinate with the rest of the swarm.

AC: 10 when biting someone. Has AC: 13 when freely moving around.

Gelatinous Cubes[]

Gelatinous Cube 2e

Gelatinous Cube from the from 2nd Edition Monstrous Manual

So nearly transparent that they are difficult to see, these cubes travel down dungeon corridors, absorbing carrion and trash along the way. Their sides glisten, tending to leave a slimy trail, but gelatinous cubes cannot climb walls or cling to ceilings. Very large cubes grow tall to garner mosses and the like from ceilings.

Ooze 2e

Ooze from the from 2nd Edition Monstrous Manual

A slimy horror that looks like wet stone or a sedimentary rock formation, the grey ooze is rarely thicker than six or eight inches, but sometimes grows to a length of 12 feet. It cannot climb walls or ceilings, so it slides, drips, and oozes along cavern floors.
