Ptoh

is a narrative entity who is mentioned in several pieces of in-game literature, as well as referenced by several of Qud's denizens. It is not directly represented in-game mechanically, but its influence can be felt through such mechanics as Glimmer and the.

Overview
Ptoh is, presumably, an alien creature whose exact species and specific characteristics are unknown. It is described as a "spacefolder", able to "fold the fabric of space and time" using its mind. It apparently can perform such feats on the sub-atomic level. It does not hail from Qud, and instead is stated to come from a "bleak" star, most commonly referred to as the darkling star.

Ptoh is said to have once been a part of a coven of spacefaring beings, which also included the Eaters of Earth, Qud's precursor race. For reasons unknown, the coven ordained that Ptoh would be imprisoned on the Eaters' home planet, within a prison that "it could not fold itself away" from. Ptoh was apparently held there for "eons", and is still there to this day. Though locked away, Ptoh is still able to exert its influence on Qud, most notably through its servants, Espers who hunt other powerful Espers to absorb their minds. Ptoh is also responsible for the creation of the ; the prism is said to induce madness in those who look into it, as it allows them to "see the world by the light of Ptoh's star, and see themselves as Ptoh does".

Ptoh appears to be held in high regard by several groups throughout Qud and other regions. The Seekers of the Sightless Way are notably interested in trading secrets about Ptoh, or more specifically, the darkling star. Catu refers to Ptoh as "the Elder", and Ptoh's pronouns in The Black Glass are capitalized, possibly as a show of respect or reverance.
