Shadows Over Ustalav
The Dark Tapestry
Little is known of the Dark Tapestry—the darkness between the stars where inhabitants of Golarion believe true madness lies. The few beings able to survive in the vast, cold void of space are too alien for even the gods to comprehend, and present one of the greatest threats to the known universe should they wish to do so.
The ancient, eldritch horrors of the Dark Tapestry are beings of immense power who—luckily—have thus shown little interest in Golarion or her solar system. Were the Great Old Ones ever to devote even a fraction of their attention to this corner of space, it could very well end existence as gods and mortals know it. While some crazed cultists and power-hungry arcanists contact aspects of the cosmic beings in the hopes that they can harness their cyclopean might for their own purposes, none can control the raw chaos these forces bring and destruction and madness are the ultimate results.
Osiriani legends speak of the mysterious Dominions of the Black and their possible connection to the enigmatic planet of Aucturn.Members of the mythical Dominion serve as emissaries and heralds of their unknowable masters and are said to reside among the darkness between the stars, sustained by the very forces that drive them to madness.
While most who know of the Dark Tapestry assume its denizens reside unimaginable distances away in the void of space, one such race of beings builds an empire beneath their very feet. The intellect devourers of the Darklands are thought to have come from the Dark Tapestry eons ago, though what their ultimate goals and motivations are or were remains a mystery only pondered by the bravest of souls.Similarily there is speculation that the gigantic tentacled creature known as the havero may originate from one of the far corners of the Dark Tapestry.
There are few known works discussing the Dark Tapestry. Notably is a work of starry observations and occult lore entitled On Verified Madness.In addition, a quasi-text of hieroglyphic formulas entitled The Last Theorum relates to the subject of the Aucturn Enigma, which is in turn believed to mysteriously tie in to the Dark Tapestry and the Dominions of the Black.
