Stitch in Time

The Stitch in Time is a magical anomaly created by the Eldest in their prehistorical war with the Firstborn.

Origin
The mythic history of the Eldest from the Codex Baruc tells that the Eldest and Firstborn had a war in the distant past. The Eldest initially had the upper hand, but the Goddess Ogdillah, creator of the Firstborn, intervened. The Firstborn built a city upon her advice, synchronizing their culture for the first time.

As the war continued, the Eldest began losing ground. Eventually, only a handful of Eldest remained. They banded together and teleported into the heart of the Firstborn city. Using the height of their magical prowess, they tore open a hole in the world, leading to some unknown else.  The city, its outskirts, and every living being within were sucked into the hole, leaving behind a place that humans would eventually name the Stitch in Time.

Known Properties
The area around the Stitch is saturated with strange magic. Unlike all other documented magic, it acts of its own accord, not requiring the action of a wizard. This magic has a tendency to unpredictably twist any object or being within its reach, with effects growing stronger and more frequent the closer one proceeds to the epicenter of the Stitch.

The Stitch is constantly surrounded by harsh winds and is site of a permanent zone of low atmospheric pressure. The river Connacht flows into the Stitch and does not leave it.

Speculated Properties
The prevailing theory is that the Stitch leads somewhere. The disappearance of the Connacht combined with the low pressure system implies that the Stitch has been constantly sucking water and atmosphere out of Ethos since it was created. This is backed up by the apocryphal "Ceskan Incident" story of a surviving Eldest asphyxiating in the open air when it was much thinner than in prehistoric times.

Prevailing theory is that wherever the Stitch leads is not part of Ethos. Attempts to probe the Stitch have been few, and with even fewer survivors .The handful of reports of the Stitch's interior all mention a dully gleaming city in the distance. Its buildings are impossibly tall and seem to be made of metal, perhaps iron or steel, with exteriors unbroken by windows.

As the Eldest were known to command magics currently unavailable to humanity, the mechanics of the Stitch and its creation are purely theoretical.
