This artifact is the ultimate psionic nullifier. Forged to keep enemies of vast psionic power at bay, the Annulus is an artifact that any psionic being should fear. It has been forgotten in the modern age, and merely finding it would precipitate a great upheaval across the planes.
The Annulus is a 1-foot-diameter ring of silvery material. Tiny slots, antennae, spheres, and other intricate projections decorate the exterior of the hoop; however, two smoothed lengths of the ring provide an adequate surface for grasping the item.
The Annulus has several powers, all of which require a wielder to tightly grasp the ring with at least one hand. When it is first grasped, knowledge of the artifact’s powers immediately flood the wielder’s mind.
The primary power of the Annulus, however, is psionic nullification. Once per year, the wielder can trigger this effect as a special action requiring 10 rounds of continuous concentration to complete. The wielder specifies a target or targets within a 100-foot radius, ranging from a specific psionic individual or item to a group of psionic beings that share the same philosophy. The nullification effect is accompanied by blasts of light, heat, and sound from the Annulus. Nonpsionic creatures and items are unaffected, as are nontargeted beings, but any psionic target—regardless of any protection it may possess—disintegrates in a terrific explosion. Nothing is left but floating dust.
It is relatively easy to nullify a single target or a small group of targets, but nullifying a more powerful being (such as a demigod or greater entity) or another major artifact taxes the Annulus to its limits. If it is used to nullify such a target, the artifact succeeds but is destroyed in the process and cannot be retrieved by any means.
