Erected by Heretic Astartes to systematically erode the boundaries of realspace, the Noctilith Crown is a colossal, arching structure engineered for warp-attunement. Cast entirely from blackstone—the mysterious, warp-reactive substance known as noctilith—this ominous edifice functions as a massive psychic amplifier, siphoning energies directly from the Immaterium to thin the veil of reality. As the Crown pulses with chaotic power, it manifests a protective warp-shield around nearby Heretic Astartes while simultaneously enhancing the powers of Chaos sorcerers and causing havoc among enemy psykers. By anchoring the corruption of the Warp directly into the physical realm, the Noctilith Crown turns any battlefield into a localised hellscape, smoothing the way for daemon manifestations and the relentless advance of the Chaos Space Marines.
