Zilcher
Thing that is known to be inter-dimensional and/or inter-dimensionless creatures that can summon you to the zilch dimension. These creatures are said to be the most powerful "things" in the realm of existence as we know it. They have the ability to contort and confine any part of reality, morph to different dimensions that are higher than the current 3rd dimension that humans are most fond of; making them impossible to even comprehend. Finally, sense they are able to contort and morph reality as they choose, they can blend in with any society, travel trough time, be omnipresent, control immortality, control prophecy, and warp space-time. They are not one to be messed with...
