Ptoh is an interplanetary being imprisoned on Qud for millennia.
“When the Eaters lived and skirred the stars, they visited the worlds of a thousand thousand different beings, and those beings likewise visited our own world. Several of those beings had assembled a coven that spanned the firmament, and they welcomed the Eaters into its fold. For ages the civilizations of the coven knew kindness and prosperity, and to all reaches of the clustered cosmos did the domain of the coven stretch. One of the beings of the coven hailed from a faraway and darkling star. With Its mind It could fold the fabric of space and time as you or I might fold a supper cloth. To the coven It was known as Ptoh.”
“For reasons we can but fathom the civilizations of the stars indicted Ptoh. It was the will of the coven that It be held on our very world in the bondage of the Eaters. They contrived for Ptoh a prison from which It could not fold Itself away, and there Ptoh languished for eons. In time, the Eaters left or perished, and the coven was forgotten to our world. Yet here Ptoh remains imprisoned.”
