Alive and wicked, the Gibbering book is both a portal and a tome. The Gibbering Book is said to have been written by the Obyriths of the Slegg who come from the Far Sphere, home of the Aberrant Gods. Bound in skin and inked in blood, the text contained prophecies, funerary incantions, demon resurrection passages and the story of the creation of the Fiend races. The book tells how the Feinds were from Dshard; a sliver of pure evil. The creators of Dshard were the Obyriths, who used it as an anchor to create a portal from Far Sphere, and esscaping the tyrany of the Aberrant Gods, forging the Slegg on the Sphere of Soth Fegg, far from the actual site of their portal – knowing the Aberrant Gods would follow, and they did; with the Kraken arriving on Deluge. The Sphere on the portal was opened became a blackened pit known as Abyss and its inhabitance were transformed into the first Fiends.
