Editing Burning a hole through existence (section)

===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.
