Yog-Sothoth (yawg-SO-thoth)

“Past, present, future, all are one in Yog-Sothoth.”
  Yog-Sothoth is the Outer God of gates, space, and time. One of the most powerful and enigmatic deities of the Elder Mythos, he is said to be a terrible, self-aware manifestation of the Dimension of Time, or even the Dark Tapestry.  

Appearance

Certainly Yog-Sothoth has great power over time and space, and can exist at multiple times in multiple realities. Distance has no meaning to Yog-Sothoth, yet the entity also seems unable to properly exist in the reality shared by most mortal life. It can only partially intrude upon this reality, taking on the shape of a slithering mass of iridescent spheres or glowing motes of light when it does. Or perhaps Yog-Sothoth can exist in this world, yet it has no real reason to do so, and what mortals see and worship and tremble before is but its shadow casting ripples into their reality.  

Worshippers

The cult of Yog-Sothoth believes that it is slowly preparing the many worlds of the universe for a new era—a new age presaged by the wakening of the Great Old Ones, during which the current inhabitants of these countless worlds will be wiped away to make way for the true masters of all.   Cults often call upon Yog-Sothoth to bless unborn children, creating monstrous hybrids that, in their own monstrous ways, help to prepare the unsuspecting world for the time when the stars themselves shall be right for the Great Old Ones to rule once again. A cult to Yog-Sothoth, Keepers of the Oldest, once resided in the town of Carrion Hill.
