Godhorrors

In the depths of the Deepest Dreaming, there lie Godhorrors: leviathans that lurk beneath seas of thoughts and dreams. Godhorrors embody the greatest fears of the world, influencing minds to increase their spread across reality.

No Physical Existence
Unlike most Higher Beings, Godhorrors are entirely conceptual - they exist only in the mind, and cannot manifest in physical reality. Instead they take hold in the minds of their emissaries: often beings of aberrant nature, occasionally ones associated with Deep Dreaming, like Dream Eaters and psychics. Because of this they are incredibly difficult to study, and much of the nature of Godhorrors is the subject of speculation.

Namesake
While most hypothesised Godhorrors reflect culture-wide fears, a small subset of them reflect those of the god, as the name implies. It is thought that, contrary to the usual nature of Godhorrors, these entities possessed greater degrees of personality and autonomy due to their connection to a specific, powerful mind. These Godhorrors are believed to have left the world along with their respective gods. Little trace of them remains.

No evidence of Godhorrors for 'folk gods', such as the Leviathan, the Four Winds, and the Evil Eye, has yet been found.

Godhorrors and Shadowmire
Since the Black Bog is a realm where nightmares can manifest, it is also a place where Godhorrors hold more power. Having said this, they still only manifest through emissaries.

Mind Flayers are associated with a Godhorror from which they are believed to have originated: 'You Know Not I', associated most strongly with fear of the unknown.

The Shadowmire, as a realm where nightmares can manifest, is a place where Godhorrors hold more power, though this manifests entirely through third parties.

You Know Not I
Associated most strongly with fear of the unknown, this Godhorror is associated with Mind Flayers, from which they are believed to have in some way originated.
