Psi-Resonant Pentacle

Psi-Resonant Pentacles were a type of anti-Psyker device used by the Imperium during the Great Crusade and Horus Heresy.^[1]

Recovered from the Vrant Cluster's Reclaimants by the Thousand Sons, these devices typically appeared as crowns or protective armor pieces and were inscribed with sigils and runes of warding. They projected an aura around themselves which may slow the passage of time or project waves of force, in addition to allowing the wearer to turn the gaze of the Warp back upon psykers. Though the Thousand Sons who recovered these artifacts ordered them destroyed with the support of the Adeptus Astronomica and the Navis Nobilite, Malcador the Sigillite dictated that they were instead to be prohibited from use and remain on Terra for further studies. The barge carrying these devices was lost during the trip to Journey, and the Pentacles appeared on battlefields throughout the galaxy during the Horus Heresy.^[1]
