History[edit | edit source]


What we call the "Demons of the Plane of Shadows" are beings from the 2nd Prime Material Plane.

The 2nd Prime Material Plane was created to be imperfect so the creatures there would need the gods in their daily lives. These creatures of weak will and great desire proved nightmarish and chaotic. They switched gods too quickly and were almost entirely dependent upon the gods for survival.

In the end, the gods got tired of micromanaging these lowly, pathetic creatures and abandoned their world, leaving them all to die.

But they didn’t die. Over the millennia they’ve twisted themselves into beings of hate and spite. They’ve changed their physical form, and unlocked the secrets of the universe through powerful magics. They become what are know known as "Demons".

The God, Malkis, may be involved with the "Demons" traveling from the 2nd Prime Material Plane to the Plane of Shadows, but his involvement is currently unknown.

After the Portal to Shadow Plane was left open by Georg and Malakai, a number of demons managed to enter the 3rd Prime Material Plane and slaughter many people in Eridon before regrouping at Heatstroke. A "pestilence" has been radiating from Heatstroke in the time since, known as a Demon Colony made of taken Flesh and Souls, growing outwards, covering turning the a fleshy substance. It is unknown what the goal of this "Demon Colony" is.

Demons have long been envious of the Prime Material Plane and its connection to the gods, and presumably wish it for themselves.

Craftsman by Matthew Burger

Humanoid. Six and a half feet tall, 250 pounds, it doesn't have sharp protruding bony plantes like many demons. It has a cool rocky-fleshy exterior. It has internal illumination like the firewyrm. Its arms are made out of some sort of malleable flesh. One of the Demons has changed one of its arms into the shape of a hammer and the other arm into the shape of a blade. The Demon is pulling something out of a forge and then beating on it with their hammer arm, then shift into the shape of another blade, and with 2 blade arms, lift the object and put it back in the forge.

Tall and muscular, these unarmored demons are unconcerned with battle, instead spending their time creating weapons and armor to aid their faction.

Beholder[edit | edit source]

Fire Wyrm[edit | edit source]

Fire Wyrm by Matthew Burger

80’ long and 5’ across, the Wyrm’s body is covered in massive plate like scales that have the texture of rough hewn limestone. When the creature is dormant or moving slowly its dark scales dominate its color pallet. But as the Fire Wyrm begins to get aggressive, it heats up, eventually hot enough to burn those that touch it, and cause the inside to glow orange and red against the dark black bones. This gives the Fire Wyrm a burning embers / burning coals look to it when its in action, and sheds light for 60’.

Breath weapon deals 20d10 magical fire damage, save for half. 35% chance for breath weapon to recharge.

Living Wall[edit | edit source]

A fleshy wall of eyes, mouths, arms, legs, tentacles, bones, teeth, scales, chitin, and hair. Can slowly move, but usually stays in place as ordered.

The wall grows and extends. Each 10’ section has its own set of HP, but is not its own creature. Someone fighting a section of flat wall is exposed to 3 attacks: 1 from directly in front, 1 from the left, and 1 from the right. If the left & right grab, the middle succeeds automatically.

Demon Colony[edit | edit source]

A sarlacc pit that devours and creates demons. From it grows a fleshy creep that expands to cover everything it comes across. Eyes may spawn on the fleshy ground, alerting the Demon Colony to the movement of inverlopers. The Demon Colony seems to eat both biomass and souls, which are both used to fuel its fleshy-ground and the creation of new Demons.

The intellect and power of the Demon Colony is unknown. Able to cast Arcane spells, has cast Chain Lightning at 12th level or greater.
