Bythos

The bythos is a guardian of space and time and ever seeks those who misuse planar and temporal magic. A bythos is a roughly humanoid creature with four arms and a body made of swirling clouds and mist. Despite their appearance, their body feels like dry stone. A bythos seeks out paradoxes caused by irresponsible planar or dimensional travelers and repairs breaches where the barriers between planes have become thin or damaged. If the mortals responsible remain in the area and cannot be convinced to cease their activities, the bythos has no qualms about removing them. Using their ability to manipulate time, a bythos might cause an opponent to quickly die of old age as time speeds up around them or cause a target to disappear from time and space.
