The Nexus Stone was a significant artifact featured in Blood Omen 2. The artifact was a brightly colored gemstone, that was capable of opening 'portals' to other locations within Nosgoth. Alongside this, the stone could be worn on the chest which allowed its user to be protected from the physical attacks of the Soul Reaver. During the course of Blood Omen 2, Kain stole the Nexus Stone from the Industrial Quarter and used it to protect himself in the final battle with the Sarafan Lord - At Janos' suggestion, Kain dropped the stone into the Hylden Gate to close it and destroy the Hylden invading Nosgoth's Material Plane.
