Burning a hole through existence

Creating an interplanar portal

The border to other planes is thin in Shaema. If you wanted to make a hole in said border, this would be the ideal land to drill.

Zebris qe Mrak infused bones with evil-natured spirits and made a circular gate out of them. After this was done she released the biggest part of the spirits from the bones. The high concentration of spirit punched a passage to whatever plane seemed appropriate. The remaining spirit in the bones kept contact with its whole. The hole in the border quickly closed off, except where the bones framed the gate.

The gate now leads practically nowhere. A cyst of existence in the fabric of nothing. A micro-plane of its own. A hole inside a crater that is Shaema.

As water seeks the point of lowest elevation, so does spirit seek the point of least resistance as it tries to pass on. Any spirit that comes near this cyst is in danger of being sucked in. This is exactly what Zebris needs; a lot of spirit to fuel a fire. A fire capable of burning a hole through to the other side of her cyst.

But it takes a special kind of flame to ignite spirit. Witches tell stories that purge-fire can be found in many lower planes, but Zebris knows no way to transfer it here. However, she does know how to transfer messages. She writes a message on spirit matter and hopes for the best/worst. Some creature answers her call and sends her a message on a peculiar spirit. It took time to decipher the strange runes and symbols. The message tells her to graft the spirit on an embryo, bathe it in spirit-infused sulfur and perform a few rituals. She does this with a kobold egg.

It took months for the egg to hatch. The creature that came out was similar to a kobold, but black, with pearl eyes that could not see. It ceaselessly gasped and grabbed with its four claws. Zebris was afraid it would die. She brought it inside the cyst and the thing went frantic, grabbing even faster towards the wall of the micro-plane. It struggled out of the witch's arms and dug its taloned arms and legs firmly inside the wall. It threw back its head, heaving painfully until it coughed out something. A hairy gray flap hung out of its mouth and began expanding as it breathed. The membrane inflated until it looked like a balloon covered in gray mold. The creature's breath normalized. It just hung there, stuck to a wall of nothing, its head hanging at a painful angle, a bulbous membrane hanging from its mouth.

In mere seconds it started feeding. Spirits got sucked into the cyst and then again into the creature through the gray-haired balloon. As it fed, its body glowed a dim blue. Blue veins appeared on its arms and legs and its claws were engulfed in blue flames. The wall around the creature slowly started to burn, leaving white ash behind. As a claw burned itself free, the creature would dig it in deeper.

Only a matter of time now.

The cyst

An artificial clearing, judging by the freshly cut stumps. In the middle, protruding from the shallow water stands an arch. A perfect three-meter tall half circle made from hundreds of pieces of bone. Even though the bones are tied together with string, the construction seems sturdy. The inside of this gate is completely black with just a hint of swirling motion. The image in the water makes it look like a complete circle, a gate into nothingness.

Inside, the cyst is a dark sphere. The black walls pick up no light from the outside world, or from the blue-burning monster thing hanging on the far side.
