Prophecy Tablets contained verses of Osiris' lost prophecies. They were provided by Brother Vance to The Young Wolf following the destruction of Panoptes, Infinite Mind on Mercury to that the Guardian could utilize them to craft weapons in The Infinite Forge. Each verse references a event that would occur in the future, or a past event that would influence the future, at the time which Osiris wrote them. Several of the prophecies on the tablets have come true since they were written, although some scholars debate whether these events truly fit the text of the prophecy, and how Osiris used the Infinite Forest to create the prophecies if they Vex cannot simulate Light.
- "Two siblings cleaved by time and space, reflections never found alone, The ending of the eldritch race—a path long seen but never known."
- "To Tower comes a war in red; an orphan sounds the empire's call. Mortal angels mourn the dead while lightless light wraps night in pall."
- "An army meets, and stands, and falls. Three nobles wage their hopeless war. In shifting madness, evil crawls. One stands above the battle's roar."
- "A charnel but effulgent orb—beacon in a loathsome dark— Fêted, fetid corpses rise—a too-long-absent gibbous spark."
- "A visitor ignites the sky, and in the truth of light it dreams: Above the dead and yet-to-die, a legion's blade with fire screams."
- "Amid the endless death one flew—Unnatural all-consuming need— And in the space between the two, accursed comprehension freed."
- "A spark of knowledge with each fall, the purpose of the endless youth. No longer shunned, dark's nameless call now brings about tenebrous truth."
- "They sowed the First, now reap the Last; forever narrows to a line Where Light will fade into the past—when all's converted, nothing shines."
- "A sacred eye that speaks in lies—upending futures in its path. The way before us to the skies shall see itself in ancient wrath."
- "A tale that's different from the rest: the thread unfurls against the clocks. The one the Speaker loved the best must have a perfect paradox."
