The Golden Claw is a powerful artifact in the hands of The Necromancer, the beloved rule of Bryn
. The device is a literal demon claw made of iron and covered with gold that holds a purple infernal stone. This stone is literally the nucleus of the Deep One
home plane and was stolen by the current owner centuries ago. The claw makes him eternally young and also grants hime the power to create and control a virtually limitless army of undead slaves as long as he has enough bodies.
The Deep One needs the stone not only to hold its realm into place, but also to create and renovate demons
.Without the artifact, it's only able to corrupt already existing life, creating abominations. This makes its demon more and more reliant on corrupting life than actually using the traditional approach of demon legions. But the consequence it fears the most about the theft is that if the Deep One would be killed before retriebing its precious stone, the body of the demon god would not be able to regenerate itself, efectivelly destroying the god forever.
The infernal stone is unnatural and not meant to exist in our world. Its sole presence on Eden
makes reality unstable, it cracks the barriers between worlds and opens the door for the creatures of the void, wich never went meant to meet the creatures of Eden. This effect is the principle behind the phenomenon known as the Space tear
. Also, as the stone is made of Hakru, also known as demon essence, it calls the Abism to the world, spreading its corruption like a broken vase spreads its content over the floor.
