Baruk-Agan, a segment of the Earth Seam, serves as a Seam Portal. After traversing it, travelers are teleported 6500 miles northward, beyond Morwuld Briin, to the Underdark domains of the Brucrumus continent, emerging at the Baruk-Sigil exit portal.
In the God Era, diminutive gnomes fleeing the vicious demon hordes of Jurusalax ventured into the depths of Krephus Sink. They navigated the winding Krephus Passage, ultimately escaping through the Baruk-Agan portal along the Earth Seam.
