Eye of Night

The Eye of Night was an ancient artefact of unknown provenance linked to the xenos artefact named the Hand of Darkness originally located on the Ratling world of Ornsworld in the Gothic Sector. It was a multifaceted obsidian gem which emitted a cloaking haze of darkness and could unleash a beam of pure black energy capable of causing massive power failures or catastrophic internal damage. The Eye of Night was stolen by the Forces of Chaos during the Gothic War and used by Abaddon the Despoiler to shut down the Imperial defences on three Blackstone Fortresses so that his troops could take control of them. The gem eventually made its way into the hands of the Chaos seer Moriana, who lost control of it to a Daemon Prince of Tzeentch. It was eventually recovered from this Daemon Prince's home, the tower known as the Pillar of Spite Fulfilled, on an unknown Daemon World in the Eye of Terror by the Inquistor Katarinya Greyfax, a squad of Grey Knights and the undead Inquisitor Phaedus Falconet Horst of the Ordo Malleus in 999.M41. Greyfax returned it to the resurrected Primarch Roboute Guilliman, who believed it held clues as to how to close the great Rift that had divided the Imperium of Man in half in the wake of the 13th Black Crusade and the fall of Cadia.
