UAC REPORT FILE FVS1EC3F
The first Project Lazarus Tethering Operation (MTC 2146/351) retrieved a small compendium from the Umbral Plains in the crypt of a destroyed tower of unknown construction (artifact reference PL E2M8). This "vade mecum" was mostly illegible, but it did contain one of the rare references to the Aranea Imperatrix - a mystical demon that is still largely unknown.
"When the gate is opened, in the fourth age, when we have risen and the masters have shown us the path, she will be come. A great blessing will be given to the key holder, for they will become one with the master, and in that holy union the power of the dark priest will be unleashed upon the heretics of the Penumbral Plain. The Aranea Imperatrix. Carried in the mind of all who follow, fed from the blood of those who fell, made with bone of rock, iron, steel and sinew. A mighty god to rule over all other gods. One become two become legion."
